Getting AttributeError: module 'collections' has no attribute 'MutableMapping' while using any pip3 command on linux Python 3.10.0

Question

Hey I have installed latest python 3.10 and pip3 on my linux (Zorin os lite 15.3 X64) machine but whenever I try to use any pip3 command I get following error For example I use the command:

pip3 freeze

I get the following error:

Traceback (most recent call last):
  File "/usr/bin/pip3", line 9, in <module>
    from pip import main
  File "/usr/lib/python3/dist-packages/pip/__init__.py", line 22, in <module>

AttributeError: module 'collections' has no attribute 'MutableMapping'

This was working fine with python 3.9 but when I updated to 3.10 I started getting this error. How can I solve this?

Answer 1

The problem is caused by an old version of pyparsing that has been vendored into pkg_resources, which is now part of setuptools.

I think if you install an updated setuptools, things will run better:

python -m pip install -U setuptools

EDIT - After installing my own version of 3.10.1 on Ubuntu 18.04, I am having this same issue. And the broken pkg_resources is preventing doing any updates, so your classic Catch-22. To begin chasing down a resolution, I've submitted a ticket on the setuptools Github repo.

EDIT2 - Based on aid on the setuptools GitHub repo, I did the following steps:

# add deadsnake repo (default or nightly)
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt install python3.10
git clone https://github.com/pypa/setuptools.git && cd setuptools && sudo python3.10 setup.py install
sudo apt install python3.10-distutils
curl -sS https://bootstrap.pypa.io/get-pip.py | python3.10
sudo apt install python3.10-venv

At this point, I am able to run pip in Python3.10, and create venvs using python3.10 -m venv virtualenv-dir.

Answer 2

update pip using code bellow

curl -sS https://bootstrap.pypa.io/get-pip.py | python3.10

Answer 3

I can try to fix it with pip install request --upgrade
