Python3 in /usr/bin/python3 but pip3 is in /opt/homebrew/bin/pip3 after upgrading MacBook why?

Installing packages using pip3, I can't seem to access them in my python3 interpreter. I then checked that after the MacBook upgrade my python3 is in:

which python3
/usr/bin/python3

and my pip3 is in:

which pip3
/opt/homebrew/bin/pip3

I think pip3 is installing packages in homebrew location and that is why system's native python3 doesn't have access to?

pip3 --version
pip 23.3.1 from /opt/homebrew/lib/python3.9/site-packages/pip (python 3.9)

How do I resolve it?

Many thanks for @nneoneo. So this is what I did exactly to sort it. I wanted to use the system python3. I first checked and upgraded the pip3 for the system's python3:

python3 -m pip install --upgrade pip

I saw a warning in the upgrade pip

Defaulting to user installation because normal site-packages is not writeable

You should consider upgrading via the '/Applications/Xcode.app/Contents/Developer/usr/bin/python3 -m pip install --upgrade pip' command.

I then checked my $HOME/.bashrc and noticed that it was pointing to the old python3 version:

/Users/YOUR_USER_NAME/Library/Python/3.8/bin

After upgrading the Mac, it comes with python3.9 so I just changed the above with:

/Users/YOUR_USER_NAME/Library/Python/3.9/bin

restart terminal and now which pip3 shows:

which pip3
/Users/YOUR_USER_NAME/Library/Python/3.9/bin/pip3

now if I install any packages using pip3 it will be using the system's python3 and not the home-brew. hope this helps

It seems like you’ve installed Python via homebrew but the system python3 is taking precedence, probably because of the ordering of $PATH.

If you’d like to always use the Homebrew Python, consider adjusting $PATH. If on the other hand you’d like to always use the system Python, you can use python3 -m pip … to use the pip for to the system Python.
