Haven’t worked in our python/pants repo in a while and (probably after upgrading to BigSur), I get this system popup every time I run pants. I tried reinstalling the python version pants is using (with pyenv), but that did not help. We’re on the latest stable pants version.

Huh

Hm, are you able to find which Python it is by using

which -a python

and trying to run

--version

on each entry? Also you could try adding

set -x

to the top of the

./pants

script - I imagine the failure might be happening when that Bash script tries to determine the interpreter to use to run Pants

All works as expected (i.e. no system popup) when running python3 directly

I’ve been running this periodically:

sudo softwareupdate --ignore "macOS Big Sur"

and today I added a new one

sudo softwareupdate --ignore "macOS Monterey"

That doesn’t help you, but /shrug

Here’s the output with `set -x`:

✓ MyPy succeeded.

Oh interesting, didn't realize it still succeeds. So does the popup happen when doing

python --version

? In particular, I suspect

/usr/bin/python

could be the culprit? MacOS deprecated Python 2

There is no popup when running either

python --version

or

/usr/bin/python

.

Maybe in interpreter discovery?

Nope. Neither

./pants

nor

./pants help

trigger it.

But

./pants test

,

./pants lint

, etc do? If so, that implies that this is not coming from the Python to run Pants itself. But rather the Python interpreters pants is using to run your own code

So I'm guessing this is interpreter discovery
