5. Add ;%GOPATH% in at the end of the variable value, and replace %GOPATH% with your Golang installation path.
6. Click "OK" to save the changes.

Mac and Linux systems:

Enter the following command in the terminal to configure environment variables:

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

In order to make this configuration permanent, you can replace the above command Add it to the ~/.profile or ~/.bashrc file.

Step 4: Test installation

In order to confirm that Golang has been correctly installed and configured, we can enter the following command on the command line to test:

go version

If you see Output similar to "go version go1.16.6 linux/amd64" indicates that Golang has been installed successfully.

At this point, we have completed all the steps of setting up the Golang environment. Next, you can start writing Golang programs, run your first Hello World program, and enjoy using Golang!
