Error “cannot download, $GOPATH not set.”

Question

Setup:

Have a look at my configuration:

$ echo $GOPATH && ls -r $GOPATH
/home/cyrus/.go
src  pkg  bin

$ echo $GOROOT &&         


        

Answer 1

If you set a variable like this:

GOPATH=$HOME/go

It won't be exported to any subprocesses. It's only available to that process. If you want to export it to subprocesses, use export:

export GOPATH

You can also combine the assignment and export:

export GOPATH=$HOME/go
