#20466 `pantsd` dies when I change a file on Linux but not Mac Issue created by yjabri Describe the bug When editing a file in a repository,

pantsd

crashes on Linux but not when using the same repository on a Mac Pants version v2.18.1 OS Are you encountering the bug on MacOS, Linux, or both? Both Additional info I posed the issue on slack. When running

pants -ldebug run archipelago/src/archipelago/__main__.py

On Linux, I'll make a change to a random file, e.g.

capstan/src/capstan/pubsub_client.py

, and see

On Mac I see

TLDR The issue is because the shebang in

../nce/.../bin/pants

is too long (

#!/home/yjabri/.cache/nce/29319df9a6ca02e838617675b5b8dd7e5b18a393c27e74979823158b85c015d9/bindings/venvs/2.18.1/bin/python3.9 -sE

) and the

-sE

gets cut off. This causes

scie-pants

to pass my

.env

(

PYTHONPATH=...

) to

python

which includes it in

sys.path

and therefore the

invalidation_globs

pantsbuild/pants
