Installing Go Lang

Go Lang, commonly referred to as Go, is a powerful programming language known for its simplicity, efficiency, and built-in support for concurrency. Before you can start writing Go code, you need to install Go on your system. In this tutorial, we will guide you through the process of installing Go on different operating systems.

Installing Go on Windows

Follow these steps to install Go on Windows:

1. Download the latest stable release of Go for Windows from the official Go website (https://golang.org/dl/).
2. Double-click the downloaded installer (e.g., go1.17.windows-amd64.msi) to start the installation.
3. Follow the instructions in the installer, choosing the desired installation location and accepting the license agreement.
4. Once the installation is complete, open the command prompt or PowerShell and verify the installation by running the following command:

go version

Installing Go on macOS

Follow these steps to install Go on macOS:

1. Download the latest stable release of Go for macOS from the official Go website (https://golang.org/dl/).
2. Double-click the downloaded package file (e.g., go1.17.darwin-amd64.pkg) to start the installation.
3. Follow the instructions in the installer, choosing the desired installation location.
4. Once the installation is complete, open the Terminal and verify the installation by running the following command:

go version

Installing Go on Linux

Follow these steps to install Go on Linux:

1. Open a terminal and use the following command to download the latest stable release of Go for Linux:

wget https://golang.org/dl/go1.17.linux-amd64.tar.gz

2. Extract the downloaded archive using the following command:

tar -C /usr/local -xzf go1.17.linux-amd64.tar.gz

3. Add Go's binary directory to the PATH environment variable. Open the ~/.profile file (or ~/.bash_profile or ~/.bashrc if they exist) and add the following line:

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

4. Save the file and exit the text editor.
5. Reload the terminal or run the following command to apply the changes:

source ~/.profile

6. Verify the installation by running the following command:

go version

Mistakes to Avoid

• Not checking the integrity of the downloaded installation package, which can lead to installation errors.
• Forgetting to add Go's binary directory to the PATH environment variable, resulting in the inability to run the go command from any location.
• Attempting to install Go from unofficial sources, which can introduce security risks or compatibility issues.
