Hi all! Running

pants check

keeps failing for me with this exception:

12:46:11.01 [ERROR] 1 Exception encountered:

Engine traceback:

ProcessExecutionFailure: Process 'Building requirements_venv.pex' failed with exit code 1.

I’ve already attempted to clean up the Pants cache, run docker prune, and restart Pants. I’ve even reinstalled Python and my PC. Usually, when I encounter issues with Pants, one of these steps resolves the problem, but unfortunately, this time, none of them have worked. Can anyone suggest any other potential solutions or troubleshooting steps I could take?

Assuming that file does exist, have you tried creating a sandbox and seeing if you can run in there manually?

I am using pants 2.27.0

https://www.pantsbuild.org/stable/reference/global-options#keep_sandboxes Maybe try from the sandbox to see if there is a different error?

When was that package released? and does it use uv? This is the same error I was seeing in https://pantsbuild.slack.com/archives/C046T6T9U/p1755096604640549

It's exactly the issue here: https://pantsbuild.slack.com/archives/C046T6T9U/p1755198752384739

and it's already fixed @wide-processor-41045. • https://github.com/jorenham/numpy-typing-compat/issues/40 • https://github.com/jorenham/optype/issues/411 Depending on your version pinning, you can probably run a

pants generate-lockfiles

and the issue will solve itself
