Can't import Quartz package.

I have installed it with this command pip install pyobjc-framework-Quartz. Tried reinstalling python, also tried python -m pip install .... With python2 or sudo python3, everything works fine but python3 is giving me this error message every time I try importing Quartz

Python version - 3.10.4

Mac version - Big Sur 11.6.5

Traceback (most recent call last):

For investigation purposes, can you try :

cd /tmp
python3 -m venv venv
source venv/bin/activate
pip install pyobjc-framework-Quartz
python your-script.py

Can you try this to see if it works :

env -i /Library/Frameworks/Python.framework/Versions/3.10/bin/python3 my_script.py

You may have files only accessible by root, try to change ownership:

sudo chown -R $(id -u):$(id -g) /Library/Frameworks/Python.framework/Versions/3.10

and run env -i ... again.

If you run :

/Library/Frameworks/Python.framework/Versions/3.10/bin/python3 -c 'import sys;print(sys.path)'
sudo /Library/Frameworks/Python.framework/Versions/3.10/bin/python3 -c 'import sys;print(sys.path)'

Is there any difference between the two ?

Try following to see if it improves :

sudo /Library/Frameworks/Python.framework/Versions/3.10/bin/python3 -m pip install pyobjc-framework-Quartz

Try this to see if there is anything unusual :

/Library/Frameworks/Python.framework/Versions/3.10/bin/python3 -X importtest -v -c 'import Quartz'

You might need to try:

python3 -m pip install [...]

Hope this will hope.
