Go Installation : —

The most popular ways to install Go Lang in your local machine are ,

• Official Documentation
• Using third party tool like apt-get in Ubuntu or HomeBrew in Mac

Using Official Documentation :~

MacBooks :

Go to the download page, choose go(latest-version).pkg. Going all the way to the end by clicking “next”, ~/go/bin will be added to your system’s $PATH after you finish the installation. Now open the terminal and type go . You should see the same output shown below.

After running the command in Terminal.

Linux :

Go to the download page, choose go(latest-version).tar.gz for based on the bits(32,64). Suppose you want to install Go in the $GO_INSTALL_DIR path. Uncompress the tar.gz to your chosen path using the command tar zxvf go(latest-version).tar.gz -C $GO_INSTALL_DIR . Then set your $PATH with the following: export PATH=$PATH:$GO_INSTALL_DIR/go/bin . Now just open the terminal and type go . You should now see the same output as above.

Windows :

Go to the download page, choose go(latest-version).windows-386.msi for 32-bit systems and go(latest-version).windows-amd64.msi for 64-bit systems. Going all the way to the end by clicking “next”, c:/go/bin will be added to path . Now just open a command line window and type go . You should now see the same output as above

Using Third Party Tools :~

GVM

GVM is a Go multi-version control tool developed by a third-party, like rvm for ruby. It’s quite easy to use. Install gvm by typing the following commands in your terminal:

bash < <(curl -s -S -L https://raw.github.com/moovweb/gvm/master/binscripts/gvm-installer)

Then we install Go using the following commands:

gvm install go(latest-version)
gvm use go(latest-version)

apt-get

Ubuntu is the most popular desktop release version of Linux. It uses apt-get to manage packages. We can install Go using the following commands.

sudo add-apt-repository ppa:gophers/go 
sudo apt-get update 
sudo apt-get install golang-go

Starting from go 1.8, The GOPATH environment variable now has a default value if it is unset. It defaults to $HOME/go on Unix and %USERPROFILE%/go on Windows.

HomeBrew

Homebrew is a software management tool commonly used in Mac to manage packages. Just type the following commands to install Go.

1. Install Homebrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. Install Go

brew update && brew upgrade 
brew install go
