 |
|
Hi there,
I get error from pip list when I setup PYTHONPATH environment to reach installed library to other software.
| Code: | echo $PYTHONPATH
:/home/fitap/venv/lib/python3.12/site-packages
|
| Code: | pip list
Traceback (most recent call last):
File "/usr/lib/python-exec/python3.12/pip", line 5, in <module>
from pip._internal.cli.main import main
File "/home/fitap/venv/lib/python3.12/site-packages/pip/_internal/cli/main.py", line 11, in <module>
from pip._internal.cli.autocompletion import autocomplete
File "/home/fitap/venv/lib/python3.12/site-packages/pip/_internal/cli/autocompletion.py", line 10, in <module>
from pip._internal.cli.main_parser import create_main_parser
File "/home/fitap/venv/lib/python3.12/site-packages/pip/_internal/cli/main_parser.py", line 9, in <module>
from pip._internal.build_env import get_runnable_pip
File "/home/fitap/venv/lib/python3.12/site-packages/pip/_internal/build_env.py", line 6, in <module>
import pathlib
File "/home/fitap/venv/lib/python3.12/site-packages/pathlib.py", line 10, in <module>
from collections import Sequence
ImportError: cannot import name 'Sequence' from 'collections' (/usr/lib/python3.12/collections/__init__.py) |
How can I solve it?
Thanks.

| The pathlib.py installed in this virtualenv is not compatible with the collections installed system-wide. On my system, there exists a system-wide pathlib that does not have the bad import. What version is this virtualenv's pathlib? If it is not the latest, does removing the bad one result in a working pip? |

According to the documentation site linked in the output you provided: | Pathlib: Install wrote: | | In Python 3.4, pathlib is now part of the standard library. For Python 3.3 and earlier, easy_install pathlib or pip install pathlib should do the trick. |
You are using Python 3.12, which is much newer than Python 3.4. Why are you still using a pathlib from pip in this version of Python? If you remove the pip version and rely on the standard library, does it work? |
