Someone on my team is having issues running

pants lint ::

on our repo. No one else on the team is able to reproduce the issue. Based on the error, it looks like Pants is trying to use Python 3.7 while building the PEX for black. However: • We have a separate resolve set up for black. It's configured to use Python 3.10.12 • Running

python --version

produces 3.10.12 • Running

pyenv versions

shows both 3.10.12 (required for everything that isn't pants in the repo) and 3.9.5 (required for pants) are installed. • Python 3.10.12 is set via

pyenv global 3.10.12

Why is it trying to use the system Python 3.7? (He's on Mac OSX with an ARM processor like most others on the team) If necessary, I can put together a stacktrace to post (I'll just need some time to obfuscate a couple things)

Is this person using

scie-pants

?

They installed pants via brew

Also, what OS is the mac on? I didn't realize they still came with python3.7

I'll ask

Yes

So is it likely that when installing Pants, it linked to Python 3.7 instead of 3.9?

Pants comes with its own runner, so it should be independent of the system. Ive had this happen a few times in the past, and have seen it in the slack chat - where on some machines, sometimes, the system python on Mac is picked up - either due to a path issue, or something else. I'm away for the next few hours, but maybe this thread might help? I recall there were several issues identified here, maybe one applies? https://pantsbuild.slack.com/archives/C046T6T9U/p1692869602927969

Thanks for all of the tips. Ultimately, uninstalling Python 3.7.9 from the system / removing it with pyenv fixed the issue
