How To Update and Upgrade Pip?

Pip is a tools or command used to manage Python packages, libraries. With the help of Pip, we can search, install, update, remove Python packages. But what about the Pip itself, “How to update or upgrade Pip?”.

Display and Check Current Python Version

We will start checking the Python version. We will use the -v options or just enter the interactive Python shell in order to display and check the current Python version. We will check both Python2 and Python3 versions like below.

Display and Check Current Python Version

Display and Check Current Pip Version

Before updating the pip we will check already installed pip versions. Like Python versions like 2 and 3 pip has versions which are called pip2 and pip3. We will use the -V option in order to print the pip version. We will use pip2 for Python2 and pip3 for Python3. Only pip command is used for default Python version where it is Python2 in this case.

Display and Check Current Pip Version

Update/Upgrade Pip with Pip Itself

The first and the most popular way to update or upgrade pip tool is using itself. We will update pip like a regular Python package by using the install -U upgrade option and provide the package name as pip. The package name for the Python version is not important but we have to use proper pip command version like pip2 op pip3 .

Upgrade Pip with Pip Itself

We can again check the version of the pip after update/upgrade with the same commands. We will see that their versions are jumped from 9.0.1 to 19.2.3 for both pip2 and pip3. Also, default pip command version is changed to the Python3 or pip3 where we issue the pip -V command.

Update/Upgrade Pip via Python On Windows

We can update the pip with the Python command or interpreter too. We will provide the -m option in order to provide the pip module with the install —upgrade option. At least we will provide the package name as pip. This is the same operation with updating pip but the implementation is a bit different.

Pip with easy_install Command

easy_install is another useful tool provided by Python. We can use easy_install in order to update and upgrade existing pip, pip2 or pip3 command. We just need to provide the package name to easy_update where it will install or upgrade given package. While using this you may need privileges like root or Administrator where you need to open the command line as Administrator in Windows operating systems.

Downgrade Specific Version of Pip with Pip Itself

Up to now we have updated/upgraded to the latest version but this not always the case. We may need to upgrade/update or downgrade to the specific pip version. We can specify the version we want to install/update/upgrade/downgrade like below. We will use a double equation sign after the package name and provide the version number. In this example we will install/update/upgrade/downgrade pip version 18.1 .

How to Upgrade Pip on Mac, Windows, and Linux

Pip is a default standard package manager used to install and manage software packages written in Python. In addition, many packages can be found in the default source for packages and their dependencies, called the Python Package Index.

Most distributions of Python come with pip preinstalled. However, upgrading pip in windows, Mac, or Linux is an important step, and we have to update from time to time to get the latest updates.

Python and OS Compatibility

Python pip works with CPython versions 2.7, 3.5, 3.6, 3.7, 3.8, and PyPy. This meaning is that pip works on the latest patch version of each of these minor versions. Previous patch versions are supported on a best-effort approach.

The pip works on Unix/Linux, macOS, and Windows.

Python in the older version of Mac

Python is the most popular programming language on the earth right now, and beginners and experienced developers widely use it. Modern Mac OS versions come with Python 2.7.x installed (or Python 2.6.1 if an older Mac OS X version), but many Python users may need to update Python in Mac OS to the newer version like Python 3.8.x or newer.

Note that we said install Python 3, not update to Python 3 because how this will work is installing Python 3 while simultaneously maintaining the Python 2 version on the Mac.

This is important because, apparently, some Mac apps rely on Python 2 version, so if you attempt to upgrade the Python 2.x to Python 3.x on Mac OS, you will eventually break some apps, perhaps critical apps.

With that in mind, you should not attempt to upgrade the current preinstalled Python release on the Mac; instead, you will have the co-installation of Python 3 for full compatibility.

Also, one thing to note is that Python 3 and Python 2 can coexist on Mac without any conflict; the usage commands will be slightly different.

How to Install Python 3.8 using Homebrew on Mac

Of course, you will have to install Homebrew on the Mac before using the Homebrew method. Still, if you’re interested in messing around with Python, then Homebrew will probably appeal to you anyway.

To install the latest version of Python 3 with Homebrew, type the following command.

Once the updated Python 3 has been installed on your Mac, you can run the following command.

You can check python 2 and python 3’s versions simultaneously.

Now, if you already have Python but do not have upgraded pip on your Mac, then see the following steps.

Upgrade pip on Mac

Mac OS X latest version with Python version 3, then pip is already installed.

If you are using Python 2.x or Python 3.x downloaded from python.org or working in the Virtual Environment created by virtualenv or pyvenv . Please make sure to upgrade pip .

Still, If pip is not installed or upgraded in your machine, you can use the following steps one by one.

Type the following command one by one.

My current Pip version is the following.

How to upgrade pip on Linux

First, check the version of Python.

Now, if your version is old, then you need to upgrade pip.

To upgrade pip on Linux, type the following command.

The above command will update your pip version.

How to upgrade pip on Windows

To upgrade PIP in Windows, you will have to open the Windows Command Prompt(CMD) and type the command below.

Note that the following way would only work if you already added Python to your Windows path.

If you have the older version of pip, then and then, upgrade the pip.

To upgrade pip on Windows, type the following command.

Conclusion

Upgrade Pip on Windows, Mac, or Linux can be easy, but due to multiple versions of Python running on a machine, sometimes it becomes troublesome.

In this tutorial, we have seen how we can upgrade pip and Python on Mac and Windows and Linux.

Как обновить pip до последней версии?

Я установил пип с использованием get-pip.py после этого pip freeze выдает ниже ошибки

Итак, я проверил 1.7 является самым последним. Если я следовал приведенным ниже шагам, и он не обновляется . Помогите мне здесь .

Обычно я просто запускаю следующие команды для обновления pip2 (= pip по умолчанию) и pip3 :

Вы должны убедиться, что вы обновляете версию (для Python 2 или 3), которую вы хотите отреагировать на команду pip без номера, в последнюю очередь.

Также обратите внимание, что при этом старые упакованные версии apt-get остаются установленными через любой другой менеджер пакетов, но добавляются новые версии, которые не имеют ничего общего с системными пакетами. В pip будут предпочтительнее -установлены пакеты, но вы не должны удалять apt-get -установлены те либо, потому что менеджер пакетов не может знать , что любая pip версия установлена в противном случае.

Команда больше не работает должным образом. Правильная команда должна быть:

скопируйте (или) загрузите ссылку на источник (заканчивается на .tar.gz)

версия должна быть изменена на последнюю версию, а ссылка может быть обновлена ​​с помощью ссылки на последнюю версию

это должно работать

pip install -U pip

Самое короткое, что я знаю.

Я думаю, что стоит упомянуть, что то, что я объясняю ниже, это то, что если вы ожидаете, что pip будет указывать на Python 2, а pip3 будет указывать на Python 3. Причина, по которой я упоминаю это, заключается в том, что когда вы обновляете pip3, он также принимает команду pip как Что ж. Это несколько странное соглашение, потому что по умолчанию python указывает на 2.x, а python3 указывает на 3.x. Что, как говорится.

Если вы хотите, чтобы последние версии Python 2.x pip и Python 3.x pip3 сосуществовали на одном компьютере (используя pip для 2.x и pip3 для 3.x), вам необходимо выполнить следующее:

В других ответах, предоставленных другими, не упоминается, что после запуска sudo pip3 установите pip —upgrade , и в итоге вы получите команду pip для установки пакетов в каталогах python 3.x вместо каталогов python 2.x.

Часть меня думает, что мы должны просто оставить pip be после обновления pip3 (даже если это pip -> pip3), но есть опасность, что люди уже ожидают, что pip функционирует как python — оба указывают на python 2.x. Другими словами, люди, вероятно, обучены использовать pip / python для python 2.x точно так же, как они обучены использовать pip3 / python3 для python 3.x.

How To Update/Upgrade A Python Package with Pip?

Pip is a popular command used to manage Python packages. Pip command is also used for updating/upgrading already installed Python packages.

List Installed Python Packages

Before updating or upgrading an installed Python package we will list already installed packages. We will use the list command which will display the complete name and the version of the installed packages.

Check If A Python Package Is Installed

In the previous example, we have just listed all installed packages and versions. We can also check if a specific python package is already installed. We will also use grep command by providing the name of the package we want to check.

List Outdated Python Packages

Pip command also provides —outdated options with the list command which will list outdated and already installed python packages.

Upgrade/Update Python Package To The Latest Version

We will use the install command with the —upgrade option and also provide the package name. In this example, we will update/upgrade the package named Django to the latest version. We will also provide the —user option. Alternatively to the —upgrade we can use -U which is the short form.

From the screenshot, we see that first the Django version 2.0 is found. Django version 2.0 is uninstalled and then Django version 2.2.5 is installed which will complete the upgrade/update of the Django.

Upgrade/Update Python Package To The Specific Version

In the previous example, we have updated the Django python package to the latest version. We can also update/upgrade a python package into a specific version which is not the latest. In this example, we will upgrade/update a specific version which is not the latest with the equal signs. We will not use the —upgrade option but specify the upgraded version.

We can see that the currently installed version is Django 2.0 but we will upgrade it into version 2.2 .

Downgrade Python Package To The Specific Version

We can also downgrade the installed package into a specific version. We will specify the Python package name with the version we want to downgrade by using equation signs like below. In this example, we will downgrade the Django package to version 2.0.

How to Update All Python Packages

With Python, the best practice of pinning all the packages in an environment at a specific version ensures that the environment can be reproduced months or even years later.

• Pinned packages in a requirements.txt file are denoted by ==. For example, requests==2.21.0. Pinned packages should never be updated except for a very good reason, such as to fix a critical bug or vulnerability.
• Conversely, unpinned packages are typically denoted by >=, which indicates that the package can be replaced by a later version. Unpinned packages are more common in development environments, where the latest version can offer bug fixes, security patches and even new functionality.

As packages age, many of them are likely to have vulnerabilities and bugs logged against them. In order to maintain the security and performance of your application, you’ll need to update these packages to a newer version that fixes the issue.

The pip package manager can be used to update one or more packages system-wide. However, if your deployment is located in a virtual environment, you should use the Pipenv package manager to update all Python packages.

NOTE: be aware that upgrading packages can break your environment by installing incompatible dependencies. This is because pip and pipenv do not resolve dependencies, unlike the ActiveState Platform. To ensure your environment doesn’t break on upgrade, you can sign up for a free ActiveState Platform account and import your current requirements.txt, ready to be upgraded.

Python Package Upgrade Checklist

In general, you can use the following steps to perform a package upgrade:

1. Check that Python is installed

Before packages can be updated, ensure that a Python installation containing the necessary files needed for updating packages is in place by following the steps outlined in Installation Requirements >

2. Get a list of all the outdated packages

To generate a list of all outdated packages:

3. Upgrade outdated packages

Depending on your operating system or virtual environment, refer to the following sections.

Update all Python Packages on Windows

The easiest way to update all packages in a Windows environment is to use pip in conjunction with Windows PowerShell:

1. Open a command shell by typing ‘powershell’ in the Search Box of the Task bar
2. Enter:

This will upgrade all packages system-wide to the latest version available in the Python Package Index (PyPI).

Update all Python Packages on Linux

Linux provides a number of ways to use pip in order to upgrade Python packages, including grep and awk.

To upgrade all packages using pip with grep on Ubuntu Linux:

To upgrade all packages using pip with awk on Ubuntu Linux:

Updating Python Packages on Windows or Linux

Pip can be used to upgrade all packages on either Windows or Linux:

1. Output a list of installed packages into a requirements file (requirements.txt):

1. Edit requirements.txt, and replace all ‘==’ with ‘>=’. Use the ‘Replace All’ command in the editor.
2. Upgrade all outdated packages:

Updating all Packages in a Virtual Environment

The easiest way to update unpinned packages (i.e., packages that do not require a specific version) in a virtual environment is to run the following Python script that makes use of pip:

Updating all Packages in a Pipenv Environment

The simplest way to update all the unpinned packages in a specific virtual environment created with pipenv is to do the following steps:

1. Activate the Pipenv shell that contains the packages to be upgraded:

1. Upgrade all packages:

Modern way to manage Python packages – ActiveState Platform

The ActiveState Platform is a cloud-based build automation and dependency management tool for Python. It provides dependency resolution for:

• Python language cores, including Python 2.7 and Python 3.5+
• Python packages and their dependencies, including:
  • Transitive dependencies (ie., dependencies of dependencies)
  • Linked C and Fortran libraries, so you can build data science packages
  • Operating system-level dependencies for Windows, Linux, and macOS
  • Shared dependencies (ie., OpenSSL)

The ActiveState Platform is the only Python package management solution that not only resolves dependencies but also provides workarounds for dependency conflicts.

Simply following the instruction prompts will resolve the conflict, eliminating dependency hell.

You can try the ActiveState Platform for free by creating an account using your email or your GitHub credentials. Start by creating a new Python project, pick the latest version that applies to your project, your OS and start to add packages. Or start by simply importing your requirements.txt file and creating a Python version with all the packages you need. The Platform will automatically pick the right package versions for your environment to ensure security and reproducibility.

Watch this tutorial to learn how to use the ActiveState Platform to create a Python 3.9 environment, and then use the Platform’s Command-Line Interface (State Tool) to install and manage it.

Ready to see for yourself? You can try the ActiveState Platform by signing up for a free account using your email or GitHub credentials.

Just run the following command to install Python 3.9 and our package manager, the State Tool:

Windows

Linux

Now you can run state install
