Make sure that GO111MODULE is not set in the environment, or that it is
set to 'on' or 'auto', and if you use a go.work file, set GOWORK=off.

Also, ensure that 'go env GOROOT' shows the root of this Go source
tree. Otherwise, the results are undefined. It's recommended to build
Go from source and use that 'go' binary to update its source tree.

Requirements may be added, updated, and removed with 'go get'.
The vendor directory may be updated with 'go mod vendor'.
