Re: [Pythonmac-SIG] why does the Mac installer hack the user's .bash_profile?

So I thought I'd try Python 2.7 on it. Normally, I advise people to never try to install a different Python on a Mac, as it's too embedded in the OS to do safely, without a great deal of domain knowledge. But here, I figured I could always wipe the disk and start over without too much loss. So I ran the installer, and tried a few things, and it didn't solve my buildbot problems. So I decided to go back to the original System python. But now I find that the installer has put the 2.7 Python on my PATH?!? It does this apparently by hacking ~/.bash_profile. In there, there's a line saying The original version is saved in .bash_profile.pysave a file which doesn't seem to exist. So, why didn't I notice myself checking the checkbox to do this in the first place, and where is my original .bash_profile file? I'm surprised you can't find it. I've always had it saved on some obvious place. But I agree that hacking the file is ugly -- it least it could ask. Feel free to file a bug and attach a patch that does this. In any case you can revert by just deleting the extra lines. Other gripes about the installer: - It names the version explicitly instead of using the Current symlink (/Libraries/Packages/Python.Package/Versions/Current). That's intentional, if you install 2.6 with the default settings and 2.7 with the 'update shell profile' section disabled you'd want python 2.6 to be on $PATH while 2.7 shouldn't be. This cannot be done without hardcoding version. - It hacks the file even if doesn't need to (e.g. if Current is already on the $PATH then the new python will be found; I think that would be easy to check). That's a bug, please file a report at bugs.python.org. - It adds a bunch of links to /usr/local/bin even though that is redundant with putting Python's bin directory on the $PATH. This makes it a headache to switch Python versions -- something developers often need to do when testing compatibility. This behavior can be disabled when you run the installer. I agree that the default should be to not install files in /usr/local, although we have had users that complained that the 3.x installers didn't do this. BTW. I've talked with Ned about this feature at Pycon and we'd like to move to a python-select command that gives you a command-line tool for managing the path to the current python (simular to gcc-select or xcode-select). That way it should be possible to do away with automaticly patching the shell profile.

A preference pane would work as well. It would need to be writting in Objective-C though, both because PyObjC is not part of the stdlib and because PyObjC plugins are not (and cannot be) isolated from each other very well. I'd prefer to have a solution that works from the command-line as well (for power-users and for integration with other tools) Ronald ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig unsubscribe: http://mail.python.org/mailman/options/Pythonmac-SIG
