![]() They were all still installed-the macOS installer didn’t throw them away-but the new install of Python 2 wasn’t finding them. If you’re switching from Python 2 to Python 3, you’ll definitely have to re-install them: the modules for each major version of Python are stored in different places.Īfter I reinstalled Python 2, I also had to sort of reinstall the modules I needed as well. If you’re re-installing Python 2, you may also have to reinstall any modules, such as lxml, holidays, and loremipsum. ![]() The Ventura version of 42 Astounding Scripts will continue to use Python, though it will be Python 3. Any command-line script that uses print, which is just about all of them, will fail. ![]() The transition from Python 2 to Python 3 is not seamless. But be aware that crontab will not necessarily import your environment, and so will not be able to find Python via env.įor that reason, I’ve just changed all /usr/bin/python and /usr/bin/env python to /usr/local/bin/python whenever I get the message that it can’t find an executable. If you were using /usr/bin/env python it will probably work without any change at all. I’m not, apparently, the only one who is still using Python 2 for some important legacy apps.īoth methods of re-installing Python 2 will install it in /usr/local/bin, so that all you need to do to get your legacy Python scripts running is to replace #!/usr/bin/python with #!/usr/local/bin/python. While there technically shouldn’t be any dependencies on Python 2, I found that this isn’t true for some older software. If you are using homebrew for other things, you may find it easier to install Python 2 using homebrew as well otherwise, other homebrew installations may try to install it anyway as a dependency. Follow the directions to double-click the Install Certificates command as well, but do so from an administrative account. It doesn’t need to be managed through homebrew, because it’s never going to be updated again. If you’ve been using Python 3 via homebrew you can continue doing so just be aware that there is now a default python3 in /usr/bin.įor your older scripts that still use Python 2, the easiest choice is the installer from. If you want Python 2, you’ll need to install it yourself. Python 2 is gone, but Python 3 replaces it. There is only one major change as far as scripting goes, and it’s expected. I finally upgraded to Monterey last month.
