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
I've never seen that one before
What happens if you run that Python outside of Pants?

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
@hundreds-father-404 here’s the output from that:
Copy code
❯ which -a python
/Users/valera/.pyenv/shims/python
/Users/valera/.pyenv/shims/python

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

✓ MyPy succeeded.
The command succeeds, btw. It’s just the popup is really annoying.

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
.
Any idea on how pants could be triggering
python2
?

Maybe in interpreter discovery?
Does this happen even if you just run a no-op
./pants
?

Nope. Neither
./pants
nor
./pants help
trigger it.

hundreds-father-404

10/28/2021, 1:01 AM
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
it sees python2, tries to execute it to check what version it declares, and ...
