With reference to #24064, this is a common occurrence when trying to automate the installation of Go programs with tools such as Puppet. System commands are run in an initially empty environment, so a command like:

GO111MODULE=on go get github.com/bitfield/cronrun/cmd/cronrun@v0.3.2

fails with this error:

missing $GOPATH

But this works fine in a 'normal' interactive environment, because GOPATH is inferred from the value of $HOME. What's missing here is not $GOPATH, per se, but $HOME.

Maybe this error message could be improved, along the lines of:

GOPATH not set; unable to default to '$HOME/go' because HOME is not set either. Please set either GOPATH or HOME.
