Was looking for way to print more output than

Generate lockfile for ...

when running

pants generate-lockfiles

. We have a case where adding new pip packages caused an incompatibility with existing packages in the resolve and (I think) what pip is doing is trying to install many of package versions to find a compatible one

(This has been an issue for our other python projects since pip introduced their new dependency resolver.)

Generate lockfiles command never finishes. The problem is, we were flying blind and didn’t know which pip package is the problem. Tried slapping the

-ldebug

,

--print-stacktrace

, and

--pex-verbosity=9

but didn’t get anything useful to track down the problematic pip package until we looked at those (ephemeral) pip logs

We can give guidance
