I guess I could wipe the pants cache dir `~ cache pants` but it would be nice if this was handled for me I suppose wink

Ah some one expects a py3 8 to be present it seems ```13 53 05 64 WARN Completed test src python pants backend docker docker build digest test py tests failed exit code 127 env python3 8 No such file or directory```

i think that that might be <https github com pantsbuild pex issues 1422>

sorry for the trouble

It can t be that issue because that issue only affects Pex 2 1 46 which Pants doesn t use because of that issue Working on it < curved television 6568> I think that s because we don t tell Pex ` venv copies` That would freeze in the python binary at the time we create venvs for tools instead of having a symlink out to the system binary picked Of course at the expense of each tool venv gaining size of python exe

IOW I think this is a generic venv issue if you don t ask for copies

I m pretty sure this very issue is one of a cluster of issues that led to the pdm creator writing up PEP 582

Indeed I get issues with my other venvs and need to recreate them whenever my python version bump a minor too
