I kept getting this error after it finished numpy's installation. Tried to change the permission of the whole folder but it doesn't work.

Trying to install it on conda-forge-arm64 platform at python 3.8.6 .

First, I don't recommend installing experimental packages into the system python directories using sudo, as that can mess up the system python installation and cause lots and lots of pain. Installing it into a user virtual env would be much safer. To do that, simply pass in another non-system path that you have write access to, and it will work fine.

That said, /Library/Python/3.8 isn't the location of the system python environment; that gets installed into /Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/. /Library/Python/3.8 doesn't exist, and system integrity protection doesn't allow even root to create it outside of some standard installation paths. (There is an issue in the command line tools python's sysconfig where it improperly reports the python library path as /Library/Python/3.8 instead of /Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/, and perhaps this is where the path you're using comes from.)
