Install golang on Linux/Ubuntu, MacOS and Windows

Setting up the Go programming environment involves installing the Go compiler and configuring your system to recognize Go-related commands. Below are step-by-step instructions for installing Go on Linux/Ubuntu, MacOS, and Windows.

Linux/Ubuntu:

1. Download Go: Open a terminal and run the following command to download the latest stable version of Go:

   sudo apt update
   sudo apt install golang

2. Set Go Environment Variables: Add the following lines to your shell profile file (e.g., ~/.bashrc or ~/.zshrc):

   export GOPATH=$HOME/go
   export PATH=$PATH:$GOPATH/bin
   export PATH=$PATH:/usr/local/go/bin

   Then, reload your profile:

   source ~/.bashrc   # or source ~/.zshrc

3. Verify Installation: Verify the Go installation by running:

   go version

   go version

MacOS:

1. Download Go: Install Go on MacOS using Homebrew. If Homebrew is not installed, you can install it from https://brew.sh/. Once Homebrew is installed, run:

   brew install go

2. Set Go Environment Variables: Add the following lines to your shell profile file (e.g., ~/.bash_profile or ~/.zshrc):

   export GOPATH=$HOME/go
   export PATH=$PATH:$GOPATH/bin
   export PATH=$PATH:/usr/local/go/bin

   Then, reload your profile:

   source ~/.bash_profile   # or source ~/.zshrc

3. Verify Installation: Verify the Go installation by running:

   go version

Windows:

1. Download and Install:

   • Download the MSI installer for Windows from the official Go website: https://golang.org/dl/

   • Run the installer and follow the on-screen instructions.

2. Set Environment Variables:

   • Right-click on "This PC" or "Computer" and select "Properties."

   • Click on "Advanced system settings."

   • Click on the "Environment Variables..." button.

   • Under "System variables," click on "New" and add a new variable:

     • Variable name: GOPATH

     • Variable value: C:\Users\YourUsername\go (Replace YourUsername with your actual username.)

   • Edit the Path variable and add the following to the end:

     • C:\Go\bin (or the path where Go is installed)

3. Verify Installation: Open a new Command Prompt and run:

   go version

These steps should help you set up Go on your Linux/Ubuntu, MacOS, or Windows system. Remember to replace any specific paths or usernames with your actual system information. Once installed, you're ready to start writing and running Go programs!
