What Is GOROOT and When Should You Change It

GOROOT is the environment variable pointing to the root directory of your Go installation, containing the standard library and compiler tools. You should change it only when you need to use a specific Go version for a project or when developing the Go toolchain itself. To change it, set the variable to the desired path before running Go commands:

export GOROOT=/usr/local/go1.22
export PATH=$GOROOT/bin:$PATH

Verify the change by running go env GOROOT.

GOROOT tells your computer where the Go programming language is installed. You usually don't need to touch it because the system finds it automatically. However, if you are working on multiple projects that require different versions of Go, you can change this setting to switch between them, similar to changing the active tool in a toolbox.
