HOW can i fix it and install python with brew? Before that, i was installed node and yarn with brew. I have tried uninstalling it and re-installing brew, but it doesn't work. Thank you!

Answer 1

I had the same issue and managed to fix it the following way:

I saw that the upgrade script tried to copy files from /private/tmp/d20221130-21318-e53mkn/ca-certificates/./2022-10-11 to /usr/local/Cellar/ca-certificates/./2022-10-11 and I got a Permission denied meaning - I (the current mac user) could not edit/create files there.

So i went to /usr/local/Cellar/ and saw that my user was not the owner of the folder ca-certificates and several others. So i just changed the onwer like this:

cd /usr/local/Cellar/

sudo chown -R REPLACE_WITH_YOUR_USERNAME:admin *

And this fix the issue for me. A simple brew upgrde upgraded all my packages after that.

Hope this helps !
