Go-tools: Cannot go get staticcheck

When I run go get it returns the following error:

If you're working in GOPATH mode, either use go get -u or manually update your version of golang.org/x/tools to at least revision 774d2ec196ee.

If you're working in module mode, this shouldn't be happening, unless you're somehow forcing an older version of golang.org/x/tools, in which case don't do that.

I had the same problem and fixed it setting module mode to on:

go env -w GO111MODULE=on

Thanks for the feedback. In my mind, GO111MODULE was on by default for Go 1.13+, but this issue proves me wrong. @ndabAP suggestion made it work.
