most pants commands failing for me with “ModuleNotFoundError: No module named ‘pex.bin’” and 
ProcessExecutionFailure: Process 'Find interpreter for constraints: CPython<4,>=3.7' failed with exit code 1.
e.g. 
./pants fmt pushdown_service/::
why would this happen? sorry, I can’t share the repo as it’s not open source
Copy code

I wonder if anaconda might be an issue. Try using pyenv to install an interpreter, and then run the Pants command with 
--python-bootstrap-search-path="['<PYENV>']"
(that’s the literal string 
<PYENV>
), just to isolate if that’s the issue.

@happy-kitchen-89482 I have a python3.11 at /Users/maheshvashishtha/.pyenv/versions/3.11.0/bin/python3.11 from pyenv. I now get `ProcessExecutionFailure: Process ‘Searching for 
python
on PATH=/Users/maheshvashishtha/.pyenv/versions/3.11.0/bin’ failed with exit code -9.`
pants was working for me on this machine earlier. I don’t know what changed
upgrading pants to 2.14 worked 🤷 but i don’t know whether this project can use pants 2.14 at the moment
removing a bunch of pants artifacts with ``rm -rf ~/.cache/pants ~/.pex dist .pids .pants.d` seemed to work

Hmmm. Glad this works now, but this is concerning. Do let us know if you encounter it again! Probably the upgrade had the same effect as nuking those caches (or some of them).
