'is not within a known GOPATH/src' error on dep init

Question

When I run dep init in project folder, the error occurs:

init failed: unable to detect the containing GOPATH: D:\projects\foo is not within a known GOPATH/src

My projects are located on another drive and not %GOPATH%/src (i.e. %USERPROFILE%\go\src).

It's a known error but it's unclear what is the solution.

How can I use dep without moving Go projects to %GOPATH%/src?

Answer 1

Go makes this choice so that there is nothing like a CLASSPATH (ie: Java) to deal with. You specify a $GOPATH that has a consistent src tree inside of it. If your repo makes references to particular git commits (rather than the ones checked out into $GOPATH/src/github.com/$githubUser/$githubProjectName), then those will be in the ./vendor directory of your project.

If you have a different Go project that uses a completely different set of checkouts, due to versioning issues, then you can have multiple $GOPATH values to deal with that.

Not at all.
