1. Ubuntu (Linux)

Step 1: Update Package Index

1sudo apt update

Step 2: Install Go

1sudo apt install golang-go

Step 3: Verify Installation

1go version

Step 4: Set Up Workspace

• Create a directory for your Go projects:

1mkdir ~/go_projects

• Set the GOPATH environment variable in ~/.bashrc or ~/.profile:

1echo "export GOPATH=$HOME/go_projects" >> ~/.bashrc
2echo "export PATH=$PATH:$GOPATH/bin" >> ~/.bashrc
3source ~/.bashrc

2. Windows

Step 1: Download Go Installer

• Go to the official Go download page and download the Windows installer.

Step 2: Run the Installer

• Double-click the downloaded .msi file and follow the installation instructions.

Step 3: Verify Installation

• Open Command Prompt and run:

1go version

Step 4: Set Up Workspace

• Create a directory for your Go projects, e.g., C:\go_projects.
• Set the GOPATH environment variable:
  • Right-click on "This PC" → Properties → Advanced system settings → Environment Variables.
  • Add a new variable named GOPATH with the path to your project directory.
  • Edit the Path variable to include %GOPATH%\bin.

3. macOS

Step 1: Install Homebrew (if not already installed)

• Open Terminal and run:

1/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Step 2: Install Go

1brew install go

Step 3: Verify Installation

1go version

Step 4: Set Up Workspace

• Create a directory for your Go projects:

1mkdir ~/go_projects

• Set the GOPATH environment variable in your shell profile (~/.bash_profile, ~/.zshrc, etc.):

1echo "export GOPATH=$HOME/go_projects" >> ~/.zshrc
2echo "export PATH=$PATH:$GOPATH/bin" >> ~/.zshrc
3source ~/.zshrc

Final Steps for All Platforms

• You can create your first Go file to test your setup:

1// main.go
2package main
3
4import "fmt"
5
6func main() {
7    fmt.Println("Hello, World!")
8}

• Run your program:

1go run main.go

This concludes the setup process for Go development on Ubuntu, Windows, and macOS.
