When I use pip3 I get this error:
Traceback (most recent call last):
File "/Library/Developer/CommandLineTools/usr/bin/pip3", line 7, in <module>
from pip import main
ModuleNotFoundError: No module named 'pip'
I tried to reinstall PIP but still reported this error, but I use python3 -m ensurepip
It told me to install Xcode command line
$ python3 -m ensurepip
$ xcode-select: Failed to locate 'python3.9', requesting installation of command line developer tools.
