Coconut crashes with AttributeError: 'frozenset' object has no attribute 'append' with python 3.12 #805

Closed aufildelanuit closed 9 months ago

aufildelanuit commented 9 months ago

I am not a proficient coconut user. I tried to install coconut to give it a try on Fedora 39, but coconut seems to crash at the first command, no matter what I type.

OS: Linux (Fedora 39) Python version: 3.12 Coconut version: v3.0.3 Shell: bash or xonsh Terminal: kitty or gnome-terminal Install method: pip or pipx

How to reproduce the issue:

Here is the traceback (user directory replaced with ~):

Coconut exiting with error: AttributeError

Edit: I could reproduce this issue in docker containers with all python versions from 3.7 to 3.12 (untested below 3.7), so I guess either I am doing something wrong, or there is a problem with coconut v3.0.3.

Duplicate of #804. Will be resolved in the next release shortly—until then you just need to downgrade cPyparsing with

pip install cPyparsing==2.4.7.2.2.1
