Pycharm: ModuleNotFoundError: No module named 'distutils.cmd'

I'm trying to use opencv module with python.
I have Python3.10.
I installed the module and with the use of Python interpreter in the command line, writing "import cv2" it works fine.
Now, I want to use opencv inside PyCharm.
I went to "File->Settings->Project->Python Interpreter" and then I tried to add the module "opencv-python" but it returned:
"Error occurred when installing package 'opencv-python'. Details.."
and clicking on Details, this is the command output:
Error: Traceback (most recent call last):

ModuleNotFoundError: No module named 'distutils.cmd'
I didn't found any working solutions for the module distutils.
I tried to install and reinstall the module "python3.10-distutils" but it is already installed.
Someone knows how to solve the problem?
Thanks in advance,
Marco

Suddenly all virtual envs fail

I use vscode and I'm working with Jupyter in this particular example. Yesterday, I was doing my work fine. Today, my venv is broken, so I deleted and started again:
python -m venv venv
./venv/Scripts/Activate
Okay, so I have brand new venv now. So lets try updating pip:
python -m pip --upgrade pip
And I get this error:

Then when I try running a cell in that notebook in VSCode I get this error:

What the heck is going on here?
Edit1
I've just proven it will error on the 3.8 global interpreter instance, even though I have other notebooks working on that. I've added a screenshot of the project.

You created a package named email, you need to rename it to some other names.

ModuleNotFoundError: No module named '_sysconfigdata_m_darwin_darwin'

I'm working on a Rally reporting tool for my team in Python, and I'm trying to package it using cx-freeze. I'm getting a ModuleNotFound error, and I'm wondering if it's because pygal isn't supported by cx-freeze (really hoping this isn't the case because I'd have to rewrite a lot of things)

cx_freeze does not include all the packages automatically. When you find ModuleNotFoundError, you need to inlcude the module explicitly in your setup like -
build_exe_options = {'packages': ['_sysconfigdata_m_darwin_darwin']}

Can't launch Jupyter Notebook ModuleNotFoundError: No module named 'resource'

I've been using Jupyter Notebook from the command line for a month now, today I didn't shut the running notebook and put my laptop to sleep for 4 hours. After turning my laptop back on I tried to run the notebook again and I'm getting the same error ever since. Please help me out.

This worked for me, should work for you.

conda update --all
this working

For me this happened while trying to install some other pip libraries. Looks like one of my pip libraries got downgraded and that caused this error. So upgrading it back resolved the issue.
pip3 install --upgrade jupyter-console
pip3 install --upgrade jupyter

To solve this, I went in the file execution.py and commented the row from timing import clock. In your machine this file is in the folder:
c:\users\chinmay\appdata\local\programs\python\python38-32\lib\site-packages\IPython\core\magics\

try this:
conda update --force conda
conda update ipython

I uninsatlled and installed the jupyter from conda..Worked fine for me

Conda crashes after installing one package - OSError: /lib64/liblzma.so.5: version `XZ_5.2' not found

I used coda for a long time, with limited problems.
However, I recently installed Miniconda2 (Miniconda2-latest-Linux-x86_64.sh) on a HPC node.
Everything works fine, but I can not install multiple packages.
What happens, is that I install one package, and after that, I get the following error when I try to install a new one:

I am not sure what I am missing here. Would someone point me towards a potential solution not involving using sudo, as I have no rights?
