   A valid GOPATH is required to use the `go get` command.
   If $GOPATH is not specified, $HOME/go will be used by default:
     https://golang.org/doc/code.html#GOPATH
   
   You may wish to add the GOROOT-based install location to your PATH:
     export PATH=$PATH:/usr/local/opt/go/libexec/bin
   ==> Summary
