- Set $GOBIN to $(go env GOPATH)/bin
- Add $GOBIN to the PATH
Should make the setup of tools like golangci-lint or golint work with a
simple `go get`.
Using $GOBIN instead of $GOPATH/bin because the goal is to have GOPATH
not being directly referenced. Also, in the future, GOBIN will have a
default value too, so we would not need to manually set it, just add it
to the path (see discussion in golang/go#23439).
Closes#14.
