Answer 1

GOPATH is an environment variable to your work-space location. GOROOT is an environment variable to your installation directory. Although GOROOT and GOPATH is automatically set (if there would not be a bug) during the installation time, to specify it manually you can follow below process. Moreover, for more information you can refer to GO's wiki page.

It is better to set GOPATH to a directory inside your home directory, e.g., $HOME/go, %USERPROFILE%\go (Windows).

1. This is a solution mac, which is tested on macOS Sierra, ver. 10.12, and also in Gogland-EAP, which has been introduced as an IDE for Go programming by JetBrains.

On your Terminal type

vim ~/.profile

in opened document on the Terminal press i and add the following path

GOPATH=/path/to/a/directory/inside/home/directory
GOROOT=/path/to/you/go/library
PATH=$PATH:$GOPATH:$GOROOT:$GOROOT/bin

press ESC and type :x. Lastly, you should restart (close and open) your terminal or Logout and Login again.

2. For Windows and Linux configuration, please refer to Go wiki page at Githab on Setting GOPATH-Golang.

CAUTION Do not set both GOROOT and GOPATH to the same directory, otherwise you will get a warning.
