I have uninstalled python3 using brew on macOS Catalina 10.15.3:
brew uninstall python3
brew list | grep python
python@2
But it still there:
which python3
/usr/bin/python3
python3 -V
Python 3.7.3
/usr/bin/python3 -V
Python 3.7.3
ls -ltah /usr/bin/ | grep python
-rwxr-xr-x 1 root wheel 31K Jan 23 16:58 python3
lrwxr-xr-x 1 root wheel 75B Dec 16 06:20 python2.7 -> ../../System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7

lrwxr-xr-x 1 root wheel 75B Dec 16 06:20 python -> ../../System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7
It's interesting but on error it shows different location of python:
python3 -bla
Unknown option: -l
usage: /Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.7/Resources/Python.app/Contents/MacOS/Python [option] ... [-c cmd | -m mod | file | -] [arg] ...
Try `python -h' for more information.
Seems it's related to Xcode.
How to delete this version python3 and reinstall python using brew?
Update:
sudo rm -f /usr/bin/python3
rm: /usr/bin/python3: Operation not permitted
Catalina comes with python3 installed by default**. You can't delete it, because /usr/bin
is on the System's read-only volume.
If you install your new python to a bin
folder that comes before /usr/bin
in your $PATH
, then it should take precedence.
** (Well OK, the first time you run it, you have to install Xcode command line tools to make it work. But that file itself is a system install.)
