Since the original reply, Apple has updated the version of the OS X 
10.10.x system Python 2.7 to 2.7.10.  So that looks good.

I was having this same problem, entered those commands and got this as a 
response:

MacBook-Pro:~ kacyjones$ /usr/bin/python2.7 -c 'import 
numpy;print(numpy.__file__)' 
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy/__init__.pyc

Any idea what that means for my system?

As a minor addendum - you can point out that “Clean My Mac” is a well-known 
piece of crap-ware that is so badly written as to be labeled by most people as 
malware.  Best possible solution would be a clean boot and restore from a 
recent clone (either CarbonCopy Cloner or SuperDuper) followed by a restore of 
intervening files from Time Machine.  Failing that, Cem’s suggestions are good.

Well, she could just download a current Python 2.7.x for OS X from 
python.org, install it, and see if that solves the problem.  That would 
be likely the easiest thing to do and is unlikely to make matters worse.  
If that doesn't work, restoring files from a backup would be in order, 
again most likely /Library/Frameworks/Python.framework/*.  As others 
have noted, running third-party apps like CleanMyMac is probably not a 
good idea, but, even if it is as crappy as its sounds, I would think it 
unlikely that it would be fooling with the Apple-supplied system Python 
in /System/Library/Frameworks.  If it did though, then the safest 
approach is to do a full Time Machine or other backup and restore the 
base system from the recovery partition and use the Migration Assistant 
to restore user files and settings from the backup.  But that's a very 
long and somewhat risky process so should only be done as a last resort.

Might that appear to work at first, but leave some subtle issues which are
not at first apparent? I don't know how intertwined Apple's Python instance
is in the day-to-day operation of the operating system (it certainly seems

Installing a python.org Python (/usr/local/bin/python*) is independent 
of and does not interfere with use of the Apple-supplied system Pythons 
(/usr/bin/python*).  Apple does ship various third-party Python packages 
(distributions) with its system Python, like numpy, but they tend to 
be old and outdated versions and there are a few Apple-only packages.  
But, should that issue arise, that can be resolved by choosing the right 
path (/usr/local/bin vs /usr/bin) or removing /usr/local/bin from $PATH.

The thing is the original message in this thread had this:
 They are getting:

The py2app glue code could be looking for Pythons in various spots

/usr/bin/python2.7 -c 'import sys;print(sys.version)'

/usr/bin/python2.7 -c 'import numpy;print(numpy.__file__)'
- 
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/pytho

If not, then it really may be necessary to restore system files which,

Re: Fixing Python install on the Mac after running 'CleanMyMac'

[MrJean1]

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.

Perhaps you can reinstall these Pythons from the CD which came with the Mac.

Correct, the Current version is just a link to 2.7.  Also, the binaries

 As others 
 have noted, running third-party apps like CleanMyMac is probably not a 
 good idea, but, even if it is as crappy as its sounds, I would think it 
 unlikely that it would be fooling with the Apple-supplied system Python 
 in /System/Library/Frameworks. 

It sounds very likely to me. These cleaner apps are often designed to
remove unnecessary system components where the author doesn't know
what they are and doesn't think anyone needs them because his system
runs fine without it, along with the mistaken belief that these take up
a lot of space or that their existence slows down performance.

Looking at the version history of this page:
https://software.com/mac/utilities/cleanmymac/1.10.0

It looks like python is removed or otherwise messed-with by a module
called System Junk (earlier Development Junk).

Version 1.9.4 _claims_ that it fixed: Sytem Junk module reliability
improved and fixed issues with python applications. - but this is
basically an admission that it was messing with the sort of thing that
could cause these issues in the first place.

Re: Fixing Python install on the Mac after running 'CleanMyMac' (fwd)

Good news, we are getting closer to understanding what to do.
This in from Ned.  I will continue after the message:

 Might that appear to work at first, but leave some subtle issues which are
 not at first apparent? I don't know how intertwined Apple's Python instance
 is in the day-to-day operation of the operating system (it certainly seems
 to be on some Linux distros), but it's possible that some Apple-specific
 package isn't available at part of the stock Python 2.7 distribution.

Installing a python.org Python (/usr/local/bin/python*) is independent 
of and does not interfere with use of the Apple-supplied system Pythons 
(/usr/bin/python*).  Apple does ship various third-party Python packages 
(distributions) with its system Python, like numpy, but they tend to 
be old and outdated versions and there are a few Apple-only packages.  
But, should that issue arise, that can be resolved by choosing the right 
path (/usr/local/bin vs /usr/bin) or removing /usr/local/bin from $PATH.

The thing is the original message in this thread had this:
 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.

But ... I just did what I should have done earlier: googled for that 
message.  And I find that the message is coming from a py2app-built 
application (and it seems I answered the question 3 years ago!):

http://stackoverflow.com/questions/10184974/py2app-is-not-copying-the-pyt
hon-framework-to-the-new-app-while-using-virutalenv

The py2app glue code could be looking for Pythons in various spots 
including the system Python.  So, let's make sure the system Python is 
still working.  On the most up-to-date 10.7 Lion system (10.7.5), typing 
the following two commands should give results the same as those shown 
(-):

/usr/bin/python2.7 -c 'import sys;print(sys.version)'
- - 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)]

/usr/bin/python2.7 -c 'import numpy;print(numpy.__file__)'
- - 
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/pytho
n/numpy/__init__.py

If not, then it really may be necessary to restore system files which, 
as I noted before, is most safely and accurately done by following 
Apple's directions to restore the system from the recovery partition and 
a good backup of user files.

So please type

/usr/bin/python2.7 -c 'import sys;print(sys.version)'

and tell me what you get as an answer.

Then type

/usr/bin/python2.7 -c 'import numpy;print(numpy.__file__)'

and again tell me what you get.

But if it isn't as Ned expects, then you may have to go back to
your backups.

Fixing Python install on the Mac after running 'CleanMyMac'

[Laura Creighton]

webmas...@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?

Laura
