Mac os golang update

Go (golang programming language)

Install Golang with Homebrew:

When installed, try to run go version to see the installed version of Go.

Setup the workspace:

Add Environment variables:

Go has a different approach of managing code, you’ll need to create a single Workspace for all your Go projects. For more information consult : How to write Go Code

First, you’ll need to tell Go the location of your workspace.

We’ll add some environment variables into shell config. One of does files located at your home directory bash_profile , bashrc or .zshrc (for Oh My Zsh Army)

Then add those lines to export the required variables

Create your workspace:

Create the workspace directories tree:

Hello world time!

Create a file in your $GOPATH/src , in my case hello.go Hello world program :

Run your first Go program by executing:

You’ll see a sweet hello, world stdout

If you wish to compile it and move it to $GOPATH/bin , then run:

Since we have $GOPATH/bin added to our $PATH , you can run your program from placement :

Prints : hello, world

Some References and utilities:

Import a Go package:

You can create Go package, as well importing shared ones. To do so you’ll need to use go get command

The command above should import github.com/gorilla/mux Go package into this directory $GOPATH/src/github.com/gorilla/mux

You can then use this package in your Go programs by importing it. Example:

Format your Go code

Go has a tool that automatically formats Go source code.

Godoc : The documentation tool

Using the godoc command, you can generate a program documentation.

You need to respect some spec in order to document using godoc . You can read more about : godoc Documenting Go code

Update golang version Linux or macOS

This article will show you how to update Go to the newest version for Linux or macOS.

To update it you need to remove your existing go folder, then reinstall the newest version. The package link provided here is the latest version at the time of this article creation. Please notify me if there is a newer version published so I can update the link.

Remove existing go

First, you need to remove your existing golang.

If you don’t know where your golang is you can use which . It will show you where your go is located.

You should remove the folder containing /bin/go . In my case, I removed /usr/local/go .

Download latest go version

Use curl to download the package. If you like to install another version, you can go to https://golang.org/dl/ .

We will download golang instalation package then extract it. It will be extracted to directory go . So if you already had directory named go in your currect directory, you should download it to another directory.
For Linux:

Extract the package

This will extract the package into folder go and move it to /usr/local

You need to update GOROOT if the installation folder is different from the previously installed go.

Verify the installation

Use this command to verify that the installation is successful.

It should show the newest golang version.

If you got something like go: command not found . You need to add $GOROOT/bin to your PATH variable.

Great! Your golang is successfully updated.

Edit: Update go version to go1.17.1

How to update the Go version

The following steps have been tested on Ubuntu. Technically, it shall work similarly in other system (Note: Some systems might require changes in directory path or to use similar command)

Step 1: Removal of existing go package

Remove the golang-go package

Remove the golang-go dependencies

Uninstall the existing Go package

Step 2: Install the new Go version

Download specific binary release for your system

Note: Replace the go release in bold above to the version for your system. List of version can be found here.

Extract the archive file

Note: Replace the go release in bold above to the downloaded one.

Place the extracted file to desired location on the system

Tips: Above location is recommended on Linux.

Step 3: Setup Go Environment (Linux)

Setup Go environment variable

Open .profile file located at home directory (

/.profile) and add the following lines:

GOROOT is the loc a tion where the Go package is installed on your system.
GOPATH is the work directory of your go project.

Next, reload environment variables for the change to take effect. (Thanks Luis V. for suggestion in the comment)

This can be done by either running the following command in terminal or doing a re-login of current shell.

• Installing Go from source — How to check out the sources, build them on your own machine, and run them.

1. Go download.

Click the button below to download the Go installer.

Don’t see your operating system here? Try one of the other downloads.

2. Go install.

Select the tab for your computer’s operating system below, then follow its installation instructions.

1. Extract the archive you downloaded into /usr/local, creating a Go tree in /usr/local/go.

Important: This step will remove a previous installation at /usr/local/go, if any, prior to extracting. Please back up any data before proceeding.

For example, run the following as root or through sudo :

rm -rf /usr/local/go && tar -C /usr/local -xzf go1.14.3.linux-amd64.tar.gz

Add /usr/local/go/bin to the PATH environment variable.

You can do this by adding the following line to your $HOME/.profile or /etc/profile (for a system-wide installation):

Note: Changes made to a profile file may not apply until the next time you log into your computer. To apply the changes immediately, just run the shell commands directly or execute them from the profile using a command such as source $HOME/.profile .

Verify that you’ve installed Go by opening a command prompt and typing the following command:

Confirm that the command prints the installed version of Go.

1. Open the package file you downloaded and follow the prompts to install Go.

The package installs the Go distribution to /usr/local/go. The package should put the /usr/local/go/bin directory in your PATH environment variable. You may need to restart any open Terminal sessions for the change to take effect.

Verify that you’ve installed Go by opening a command prompt and typing the following command:

Confirm that the command prints the installed version of Go.

1. Open the MSI file you downloaded and follow the prompts to install Go.

By default, the installer will install Go to Program Files or Program Files (x86) . You can change the location as needed. After installing, you will need to close and reopen any open command prompts so that changes to the environment made by the installer are reflected at the command prompt.

Verify that you’ve installed Go.

1. In Windows, click the Start menu.
2. In the menu’s search box, type cmd , then press the Enter key.
3. In the Command Prompt window that appears, type the following command:

Confirm that the command prints the installed version of Go.

3. Go code.

Установка Go на macOS

Для начала процесса установки Go в операционной системе macOS, просто кликните на скачанный пакет Go.

Пользователи, что предпочитают работу с командной строкой, для начала процесса инсталляции могут использовать следующую команду.

Далее просто следуйте инструкциям, пока не появится окно, сообщающее о завершении установки.

Настройка рабочего пространства Go

Для настройки переменных окружения требуется отредактировать файл

/.profile file (или их эквивалент). Обычно нужны три переменные окружения — GOROOT , GOPATH и PATH .

GOROOT находится там, где был установлен пакет Go.

GOPATH является местом рабочей директории. К примеру, папкой нашего проекта является

Теперь настроим переменную PATH для получения общего доступа к бинарной системе.

Установка инструмента управления зависимостями

govendor является инструментом, что используется для эффективного управления зависимостями приложений Go. Его также нужно установить.

Узнать установленную версию Go

Установка и настройка Go успешно завершена. Можем проверить, какая именно версия языка Go была установления в системе.

Администрирую данный сайт с целью распространения как можно большего объема обучающего материала для языка программирования Go. В IT с 2008 года, с тех пор изучаю и применяю интересующие меня технологии. Проявляю огромный интерес к машинному обучению и анализу данных.
