not sure if this is an issue to report, or in 
pants
or 
scie-pants
if so.. 🧵
while triaging an issue.. I’ve used both 
pants
and 
./pants
and wound up with this scenario:

i.e. seems like I got an venv active and that tripped things up
e
Pants. The algorithm is pretty simple - either use RUST_LOG=trace, or other output to determine if scie-pants is done. The log output here says scie-pants is done.
After all scie-pants does an execv - so its trace is fully replaced and the exec'd to process is all that remains.

ok, great. so, running pants with some venv active breaks stuff in non obvious ways..

says broken link?
What is in that

dir when you inspect?

What about

?
Is that a broken link? I.E. follow all the way and see if broken somewhere.

sorry for my bad shell pastes..
I followed the links to the end above

Ok, that was the final missing piece of info. So /Users/andreas.stenius/.pyenv/versions/3.9.13/bin/python3.9 is a real file.
c
yes

Did you hack on /Users/andreas.stenius/src/github/kaos/pants/build-support/pants_venv line 20?
There are 2 possible missing files, python and the file it executes - find out which
You know all this though. Report back after you get stuck for real!
c
not hacked on any.. this is a clean checkout of https://github.com/psontag/pexample/tree/pants-reproduce-field-issue yea… sorry just jumped into answering your questions 😛
e
Ok, you should hack on that file to debug then

Ah, ok your 
ll
did show that the terminal file was a file and not a link. Your terminal bling is really hard to read for sure in a support context! Sorry about that.

c
yea… should see what can be done to not include the bling when copying… even a screenshot could’ve been better in this case..
e
Yeah, I really don't like screen shots for support - can't copy paste, but better in this case.
