Managing go versions with gvm

gvm is a way to manage multiple go versions. It has some strange behaviour with go paths that I don't really understand. It essentially sets your GOPATH to a different directory for every version. You could just append your real go path, but it seems like there might be tooling that doesn't expect gopath to be a list. My solution was to:

gvm install go1.8
gvm use go1.8
gvm pkgenv

This pops $EDITOR which you can use to set your go path to $HOME/go. Check it with:

go env
