执行错误：pip install opencv-python

Question

So im trying to install OpenCV-Python using my administrator command prompt in windows 10 and my version of python is 3.9 and pip is fully updated.. here is the (massive) error I get after trying to execute pip install opencv-python

This is what happens:

C:\WINDOWS\system32>pip install opencv-python

There is a LOT more after that but I am unable to post the error in its entirety as it says "it looks like your post is mostly code. please add some more details"

My gut feeling is that all of this is occurring because my python directory isn't in C:\\ProgramFiles\\Python or maybe it has to do with the fact that I installed python via the windows app store.

I know its a lot of code and I am literally just beginning to get into this because I am trying to create a script that will scrape eBay thumbnails and download the images from a start page with search terms entered, if and only if those images contain numbers. Hence why I am trying to install OpenCV.

Any help would be greatly appreciated. The last time I ever coded anything was when I was 12 years old playing Never Winter Nights which used something like C+ so I generally know my way around under the hood but am totally new to python specific commands and am hoping this little project I am attempting will teach me a useful amount about python and also automate this whole "needle in a haystack" search for images with numbers in them.

Cheers
