Configuring Go

Go is now installed, but in order to use the tools we must ensure it is properly configured. To make calling the tools easier, we need to add our go/bin path to the PATH environment variable.

Note

On Unix systems, you should add export PATH=$PATH:/opt/go/bin (make sure it is the path you chose when downloading the source) to your .bashrc file.

On Windows, open System Properties (try right-clicking on My Computer) and under Advanced, click on the Environment Variables button and use the UI to ensure the PATH variable contains the path to your go/bin folder.

In a terminal (you may need to restart it for your changes to take effect), you can make sure this worked by printing the value of the PATH variable:

echo $PATH

Ensure the value printed contains the correct path to your go/bin folder, for example, on my machine it prints as:

/usr/local/bin:/usr/bin:/bin:/opt/go/bin

Note

The colons (semicolons on Windows) between the paths indicate that the PATH variable is actually a list of folders...
