#19518 pants suddenly failing to build / run pex file Issue created by nicholaslanger Describe the bug I'm currently working on a repo with several python scripts that bundled into their own respective pex files. Just today my pants cli was unable to run the target script. This issue occurred just after I destroyed and created a new venv with a different python version and attempted to run pip install on our same requirements file. The main error that occurred in the stack trace was error: command 'cmake' failed: No such file or directory ERROR: failed building wheel for pyarrow ERROR failed to build one or more wheels [stacktrace] pex.jobs.Error: Executing /Users/nlanger/.cache/pants/named_caches/pex_root/venvs/[long id]/[long id]]/pex ... ... During the above exception another exception occurred: .... pex.resolver.Untranslatable: pid 15071 -> /Users/nlanger/.cache/pants/named_caches/pex_root/venvs/[long id]/[long id]]/pex ... I tried to delete everything from ./cache/pants but still failed. another coworker of mine has the same issue but I couldnt resolve it for her a few days ago. Has this been seen before? can changing venvs cause problems? Pants version 2.9.0 OS Mac OS Additional info Add any other information about the problem here, such as attachments or links to gists, if relevant. pantsbuild/pants
