I wonder if it s improper metadata from the dependency like this <https www pantsbuild org docs python third party dependencies requirements with undeclared dependencies>

Note ctypes is a standard lib package even if you don t know that note it is not in site packages above This means your pyenv 3 7 13 interpreter install is broken

incalculable-yacht-75851 · Answer

right This might be a my machine problem since i m on an M1 mac and can t use anything less than Python 3 9

incalculable-yacht-75851 · Answer

I ll see if I can get this running in CI

hundreds-father-404 · Answer

Ah I have to use Py39 for anything to work too I set that in ` pants rc` config file <https www pantsbuild org docs options pantsrc file>

whoops `pyenv uninstall 3 7 13` fixed that issue Now I m onto this one ```09 52 30 95 ERROR 1 Exception encountered ProcessExecutionFailure Process Run setuptools build meta legacy for products datalogue dtl python sdk dist failed with exit code 1 stdout stderr build backend pex pex shim sh private var folders qs 501mdfv5309fbjv3wxcln9gw0000gp T process executionrvxpZ6 chroot cache pex root venvs 0621634ca5ceb222971326822525fc4b02f719c6 82b4909efecc2bbe750b1ca2cb66a81ec429d15a pex Users KHowa8 cache pants named caches pex root venvs s e5a3085f venv bin pyt bad interpreter No such file or directory build backend pex pex shim sh line 54 private var folders qs 501mdfv5309fbjv3wxcln9gw0000gp T process executionrvxpZ6 chroot cache pex root venvs 0621634ca5ceb222971326822525fc4b02f719c6 82b4909efecc2bbe750b1ca2cb66a81ec429d15a pex Undefined error 0 Use ` no process cleanup` to preserve process chroots for inspection ```

< hundreds father 404> I did use the pants rc file which the project overrides the constraints so not sure how to handle that

incalculable-yacht-75851 · Answer

FYI I was able to get the package command working in CI It s a my machine issue that I ll work out later

hundreds-father-404 · Answer

hmmm I m not sure what that is maybe try `mv ~ cache pants ~ cache pants old` it could be a corrupt cache

Okay great If you re willing to keep the old cache around until we hear back here < enough analyst 54434> would it help to have a copy of the cache

incalculable-yacht-75851 · Answer

I ve got it if you want it

enough-analyst-54434 · Answer

I don t think we need to see the cache You should expect any venv that was built from a Python you later remove to fail Python venvs are not hermetic Various bits depending on the venv technology mvenv or virtualenv will link back to the original interpreter
