#91423 — Fixing Python install on the Mac after running 'CleanMyMac'

webmaster@python.org just got some mail from some poor embarrased
soul who ran this program and broke their Python install.

They are running Mac OSX 10.7.5

They are getting:

     Utility has encountered a fatal error, and will now terminate.  A
     Python runtime could not be located. You may need to install a
     framework build of Python or edit the PyRuntimeLocations array in this
     applications info.plist file.  Then there are two oblong circles. One
     says Open Console. The other says Terminate.

So https://docs.python.org/2/using/mac.html says:

   The Apple-provided build of Python is installed in
   /System/Library/Frameworks/Python.framework and /usr/bin/python,
   respectively. You should never modify or delete these, as they are
   Apple-controlled and are used by Apple- or third-party software.

So, I assume this poor soul has done precisely that.

What do I tell her to do now?

FWIW, I recently upgraded an older MacBook to Mac OS X 10.7.5 and there are 3 different versions of Python in /System/Library/Frameworks/Python.framework, see:

$ ls /System/Library/Frameworks/Python.framework/Versions/
2.5	2.6	2.7	Current


It is unclear whether MacOS X 10.7.5 installed all four of these Python versions.  The older one(s) may be left over from the previous MacOS X release on the machine.  But all are Apple builds of the Python version, for example:

$ python2.7
Python 2.7.1 (r271:86832, Jul 31 2011, 19:30:53) 
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> ^D


In addition, there is a link in /usr/bin to the python2.X, pythonw2.X and python2.X-config file for each version, see

$ ls -la /usr/bin/python*
-rwxr-xr-x  2 root  wheel  62752 May 21 19:06 /usr/bin/python
-rwxr-xr-x  6 root  wheel    925 May 21 19:06 /usr/bin/python-config

Perhaps you can reinstall these Pythons from the CD which came with the Mac.  Let me know if you need  more info.

For compatibility with applications linked on older OS X releases, Apple 
customarily ships more than one version of Python frameworks with OS X.  
There are actually three versions of the system Python frameworks there: 
you should see that "Current" is actually a symbolic link to "2.7".  All 
of those versions are shipped as part of OS X 10.7.

Correct, the "Current" version is just a link to "2.7".  Also, the binaries '/usr/bin/python{,w}" seem to be copies of the "/System/Library/.../Versions/2.7/bin/python{,w}" files.
