Hi @go101, could you please provide more context here? It would be helpful if you could run go env and give the output, as well as give more context about what exactly you think is misleading/missing about the current error message.

@katiehockman katiehockman added WaitingForInfo Issue is not actionable because of missing required information, which needs to be provided. modules labels May 1, 2019

go env doesn't help for this issue.

What I mean is the error message indicates that a version is allowed to be specified in the module directive, but in fact, it is not allowed.
