How to update ruby linux

Installing Ruby

With package managers or third-party tools, you have plenty of options to install and manage Ruby.

You may already have Ruby installed on your computer. You can check inside a terminal emulator by typing:

This should output some information on the installed Ruby version.

Choose Your Installation Method

There are several ways to install Ruby:

• On a UNIX-like operating system, using your system’s package manager is easiest. However, the packaged Ruby version may not be the newest one.
• Installers can be used to install a specific or multiple Ruby versions. There is also an installer for Windows.
• Managers help you to switch between multiple Ruby versions on your system.
• Finally, you can also build Ruby from source.

On Windows 10, you can also use the Windows Subsystem for Linux to install one of the supported Linux distributions and use any of the installation methods available on that system.

Here are available installation methods:

Package Management Systems

If you cannot compile your own Ruby, and you do not want to use a third-party tool, you can use your system’s package manager to install Ruby.

Some members of the Ruby community feel that you should avoid package managers to install Ruby and that you should use dedicated tools instead.

It is possible that major package managers will install older Ruby versions instead of the latest release. To use the latest Ruby release, check that the package name matches its version number. Or use a dedicated installer.

apt (Debian or Ubuntu)

Debian GNU/Linux and Ubuntu use the apt package manager. You can use it like this:

yum (CentOS, Fedora, or RHEL)

CentOS, Fedora, and RHEL use the yum package manager. You can use it like this:

The installed version is typically the latest version of Ruby available at the release time of the specific distribution version.

snap (Ubuntu or other Linux distributions)

Snap is a package manager developed by Canonical. It is available out-of-the-box on Ubuntu, but snap also works on many other Linux distributions. You can use it like this:

We have several channels per Ruby minor series. For instance, the following commands switch to Ruby 2.3:

portage (Gentoo)

Gentoo uses the portage package manager.

To install a specific version, set RUBY_TARGETS in your make.conf . See the Gentoo Ruby Project website for details.

pacman (Arch Linux)

Arch Linux uses a package manager named pacman. To get Ruby, just do this:

This should install the latest stable Ruby version.

Homebrew (macOS)

Ruby versions 2.0 and above are included by default in macOS releases since at least El Capitan (10.11).

Homebrew is a commonly used package manager on macOS. Installing Ruby using Homebrew is easy:

This should install the latest Ruby version.

FreeBSD

FreeBSD offers both pre-packaged and source-based methods to install Ruby. Prebuilt packages can be installed via the pkg tool:

A source-based method can be used to install Ruby using the Ports Collection. This is useful if you want to customize the build configuration options.

More information about Ruby and its surrounding ecosystem on FreeBSD can be found on the FreeBSD Ruby Project website.

OpenBSD

OpenBSD as well as its distribution adJ has packages for the three major versions of Ruby. The following command allows you to see the available versions and to install one:

You can install multiple major versions side by side, because their binaries have different names (e.g. ruby27 , ruby26 ).

The HEAD branch of the OpenBSD ports collection might have the most recent version of Ruby for this platform some days after it is released, see directory lang/ruby in the most recent ports collection.

Ruby on OpenIndiana

To install Ruby on OpenIndiana, please use the Image Packaging System (IPS) client. This will install the Ruby binaries and RubyGems directly from the OpenIndiana repositories. It’s easy:

However, the third-party tools might be a good way to obtain the latest version of Ruby.

Windows Package Manager

On Windows, you can use the Windows Package Manager CLI to install Ruby:

Other Distributions

On other systems, you can search the package repository of your Linux distribution’s manager for Ruby. Alternatively, you can use a third-party installer.

Installers

If the version of Ruby provided by your system or package manager is out of date, a newer one can be installed using a third-party installer.

Some installers allow you to install multiple versions on the same system; associated managers can help to switch between the different Rubies.

If you are planning to use RVM as a version manager you don’t need a separate installer, it comes with its own.

ruby-build

ruby-build is a plugin for rbenv that allows you to compile and install different versions of Ruby. ruby-build can also be used as a standalone program without rbenv. It is available for macOS, Linux, and other UNIX-like operating systems.

ruby-install

ruby-install allows you to compile and install different versions of Ruby into arbitrary directories. chruby is a complimentary tool used to switch between Ruby versions. It is available for macOS, Linux, and other UNIX-like operating systems.

RubyInstaller

On Windows, RubyInstaller gives you everything you need to set up a full Ruby development environment.

Just download it, run it, and you are done!

Ruby Stack

If you are installing Ruby in order to use Ruby on Rails, you can use the following installer:

• Bitnami Ruby Stack provides a complete development environment for Rails. It supports macOS, Linux, Windows, virtual machines, and cloud images.

Managers

Many Rubyists use Ruby managers to manage multiple Rubies. They allow easy or even automatic switching between Ruby versions depending on the project and other advantages but are not officially supported. You can however find support within their respective communities.

asdf-vm

asdf-vm is an extendable version manager that can manage multiple language runtime versions on a per-project basis. You will need the asdf-ruby plugin (which in turn uses ruby-build) to install Ruby.

chruby

chruby allows you to switch between multiple Rubies. It can manage Rubies installed by ruby-install or even built from source.

rbenv

rbenv allows you to manage multiple installations of Ruby. While it can’t install Ruby by default, its ruby-build plugin can. Both tools are available for macOS, Linux, or other UNIX-like operating systems.

RVM (“Ruby Version Manager”)

RVM allows you to install and manage multiple installations of Ruby on your system. It can also manage different gemsets. It is available for macOS, Linux, or other UNIX-like operating systems.

Uru is a lightweight, multi-platform command line tool that helps you to use multiple Rubies on macOS, Linux, or Windows systems.

Building from Source

Of course, you can install Ruby from source. Download and unpack a tarball, then just do this:

By default, this will install Ruby into /usr/local . To change, pass the —prefix=DIR option to the ./configure script.

You can find more information about building from source in the Ruby README file.

Using the third-party tools or package managers might be a better idea, though, because the installed Ruby won’t be managed by any tools.

Update RubyMine

By default, RubyMine is configured to check for updates automatically and notify you when a new version is available. Updates are usually patch-based : they are applied to the existing installation and only require you to restart the IDE. However, sometimes patch updates are not available, and a new version of RubyMine must be installed.

When RubyMine updates to a new major release, it opens the What’s New in RubyMine tab in the editor with information about the changes, improvements, and fixes. To open this tab manually, select Help | What’s New in RubyMine .

If RubyMine does not have HTTP access outside your local network, it will not be able to check for updates and apply patches. In this case, you have to download new versions of the IDE and install them manually as described in Standalone installation.

Toolbox App

If you installed RubyMine using the Toolbox App, it will suggest you to update the IDE when a new version is available.

Automatically update all managed tools

Open the Toolbox App and click in the top right corner.

In the Toolbox App Settings dialog, expand Tools and select Update all tools automatically .

If you disable this option, you will need to click Update next to any instance when a newer version comes out.

You can also configure the update policy for every managed IDE instance separately.

Configure the update policy for a specific instance

Open the Toolbox App, click next to the relevant IDE instance, and select Settings .

In the instance settings dialog, select the update channel to use for this IDE instance:

Update to Release : Update only to stable releases that are recommended for production.

To Release and Early Access Program : Includes updates to release candidates, beta releases, and EAP builds, which are not recommended for production and include feature previews.

Standalone instance

If you installed RubyMine manually, the standalone IDE instance will manage its own updates. It will notify you when a new version is available (show you a notification in the Event Log tool window). You can choose to update the current instance, download and install the new version as a separate instance, postpone the notification, or ignore the update entirely.

Configure the update policy

To manage the RubyMine update policy, open Settings/Preferences Ctrl+Alt+S and select Appearance & Behavior | System Settings | Updates .

If the IDE instance is managed by the Toolbox App, these settings will affect only plugin updates.

The Updates page contains the following settings:

Select whether you want RubyMine to check for updates automatically and choose an update channel.

Early Access Program : Provides all updates, including major version EAP builds and minor version Preview builds. This channel is not recommended for production development.

RubyMine can be updated only to a minor Preview version, but not to a major EAP build. For example, you can update RubyMine 2021.1.1 to 2021.1.2 , but not to 2021.2 EAP . The 2021.2 EAP version in this case will be installed as an additional instance.

EAP versions can be updated to both newer EAP and stable RubyMine versions. If an EAP version is updated to a stable version at some point, the name of the original installation directory does not change.

Beta Releases or Public Previews : Includes stable releases, release candidates, and beta releases. Some updates in this channel may contain minor bugs and feature previews.

Stable Releases : Includes only stable releases that are recommended for production.

You can choose the update channel only if you are using a stable version . For EAP builds, the channel is always set to Early Access Program .

Select whether you want RubyMine to check for new versions of plugins automatically.

Check for updates immediately.

Alternatively, from the main menu, select Help | Check for Updates on Windows or Linux, or RubyMine | Check for Updates on macOS.

Show the list of updates that were ignored. These updates will not be suggested until you remove them from the list of ignored updates.

If you remove several updates from the ignored list, only the most recent will be offered for download when you check for updates.

Item	Description

Show What’s New in the editor after an IDE update	Open a tab with information about new features and improvements after a major IDE update.

Snap package

If you installed RubyMine as a snap package, it will manage updates automatically. All snaps are updated automatically in the background every day. You can also get the latest version of all snaps manually at any time by running the following command:

Or if you want to update only the RubyMine snap:

Как обновить ruby ​​на linux (ubuntu)?

Я новичок на рубине и linux, поэтому я уверен, что это тривиально, но я пока не знаю. В настоящее время у меня установлен рубин 1.8.7, и я хочу обновить его до ruby ​​1.9. Как я могу это сделать?

ОТВЕТЫ

Ответ 1

должен сделать трюк.

Вы можете найти, какие библиотеки доступны для установки через

Итак, я просто сделал apt-cache search ruby | grep 9 , чтобы найти его.

Вам, вероятно, придется вызывать новый Ruby как ruby1.9 , потому что Ubuntu, вероятно, по умолчанию будет 1.8, если вы просто наберете ruby .

Ответ 2

На самом деле нет причин удалять ruby1-8, если кто-то еще не знает лучше. Выполните команды ниже, чтобы установить 1.9, а затем связать ruby, чтобы указать на новую версию.

Ответ 3

В Ubuntu 12.04 (Precise Pangolin) я получил эту работу со следующей командой:

Ответ 4

Теперь Ruby теперь v2.0. Такие программы, как Jekyll (и я уверен, многие другие), требуют этого. Я просто побежал:

sudo apt-get install ruby2.0

Надеюсь, что поможет

Ответ 5

Автор в этой статье утверждает, что было бы лучше избегать установки Ruby из локального диспетчера пакетов, но для использования RVM.

Вы можете легко переключаться между различными версиями Ruby:

Ответ 6

приведенное выше неплохо, однако его отличие от 11.10

который установит ruby ​​1.9

при связывании вы просто используете ls /usr/bin | grep ruby он должен выводить ruby1.9.1

а затем вы sudo ln -sf /usr/bin/ruby1.9.1 /usr/bin/ruby , и вы отправитесь на гонки.

Ответ 7

Во-первых, какую версию ubuntu вы используете, может быть проще всего перейти на тот, который имеет ее.

Затем включите backports (системное меню, администратор, источники программного обеспечения) и выполните поиск в синаптическом режиме.

Наконец, найдите ppa для него.

Ответ 8

Если вы похожи на меня, используя ubuntu 10.10 & Амп; не можете найти последнюю версию, которая теперь

или загрузите файл *. deb🙂

& помните, что он не изменит вам старую версию ruby ​​
