更新 python 版本后使用 pipenv 的错误

Question

recently I have updated my default python to be 3.10 but I realized that some parts of my OS started to broke;

I can use python -m venv venv and it works like a charm, but if I try to activate a pipenv shell I do receive some errors It has started by raising errors in the collections.MutableMapping so I changed it to collections.abc.MutableMapping ... But it doesn't stop raising errors and I can't remove the pipenv.

When I try to pipenv shell or even pipenv --rm I do receive the same message error

ImportError: cannot import name 'InvalidHeader' from 'requests.packages.urllib3.exceptions' (/usr/lib/python3/dist-packages/pipenv/vendor/requests/packages/urllib3/exceptions.py)

As I can't find references on how to fix this, any help you can provide will be really appreciated guys.

Regards, Leonardo

Running with a new Ubuntu 22.04 system, I faced the same urllib3 collections issue you report as your initial problem:

$ pipenv install
Traceback (most recent call last):
  <snip>
  File "/usr/lib/python3/dist-packages/pipenv/vendor/requests/packages/urllib3/_collections.py", line 2, in <module>
    from collections import Mapping, MutableMapping
ImportError: cannot import name 'Mapping' from 'collections' (/usr/lib/python3.10/collections/__init__.py)

I found a discussion of this in the pipenv github's issue page here: https://github.com/pypa/pipenv/issues/5088

Apparently there is a problem with Python 3.10 with the apt-installed version of pipenv. I suppose the apt repositories should obtain an updated pipenv? In any case, taking the input from amod-amatya , I installed pipenv via pip (on my system, my packages are installed via sudo , but running as a non-sudo user should work as well):

sudo pip install --upgrade pipenv

FWIW, I didn't uninstall the apt version of pipenv. With that pip-installed pipenv version, pipenv now works for me:

$ pipenv --version
pipenv, version 2022.5.2

$ pipenv install
