title: How to remove an installed package using go modules
body: <p>I've installed a package using go modules (go get in Go 1.13) and now I want to remove it. In the <a href="https://github.com/golang/go/wiki/vgo" rel="noreferrer">documentation</a> there is nothing about this and in <a href="https://golang.org/pkg/cmd/go/internal/get/" rel="noreferrer">go get docu</a> neither.</p>
  
  <p>Removing the package from go.mod manually doesn't solve the issue so it remains in go.sum.</p>
  
  <p>How should I remove a package in a clean way?</p>
