While trying to troubleshoot a test, I found that I could no longer use

repl

on our 3rdparty libraries:

% ./pants --no-pantsd repl 3rdparty/python:zipp                                                                                                           cb/chartbeat (mybranch ⚡) beathound

This works on our main branch using 1.27. Did something change with how

pants

works with

python_requirement_library

target types? I am still upgrading our

pants.toml

file so it might be something there.

that is unexpected. even more unexpected is that it doesn’t work on 2.0.x either

you were able to reproduce it? I am running on 1.30.1

@jolly-midnight-72759: and is this on v1 or v2?

v1 and v2

with the same error?

doh. just worked on v1.

even more curious, i’m not seeing an issue in 2.0.x

./v2

has

./pants --no-v1 --v2 "$@"

in it

@jolly-midnight-72759: would you be able to file a tiny sketch of a repro on a ticket?

yup.

i’m also not using

ipython

, although that might not be relevant.

My end goal is to get to 2.0.x. So maybe I should just hack on that version.

@jolly-midnight-72759: possibly… a middle ground is to get as stable as possible on each release, without releasing them.

Do you still need the bug report? Sounds like it is a known issue.

i can file it. but would be interested in discussing the priority for you… if you are able to stably move to 2.0.x, we might not backport the fix, since we’re busying preparing for the 2.0 launch

I'll switch over to 2.0.x and see what I encounter there. I already have my test suite using v2.

https://github.com/pantsbuild/pants/issues/10897 is the issue
