easy_install broken on Mac

I have copied my home folder from a Mac OSX 10.5 to a new Mac OSX 10.6. This broke east_intall for binary packages. For example if I use Python 2.5:

This is not a celery specific question. I get similar errors with lxml, matplotlib, scipy, etc. The problem occurs with all binary packages, not pure python packages. What am I doing wrong?

> which easy_install
/Library/Frameworks/Python.framework/Versions/Current/bin/easy_install
> which easy_install-2.6
/usr/bin/easy_install-2.6

It is difficult to tell for sure with the abbreviated tracebacks you included. One possibility is that the separate Python 2.5 you had installed on Mac OS X 10.5, most likely using a python.org installer, did not get copied over. If so, you either need to install a similar Python 2.5 there or move /Library/Frameworks/Python.frameworks from the old installation. Or you should update to using a newer Python, either a system one or one from python.org or one of the third-party open source distributors for Mac OS X, like MacPorts or homebrew or Fink or ActiveState.

Another possibility is that you need to install the optional MacOSX 10.4u SDK from the Xcode 3 installer for Mac OS X 10.6. If that is the case, you should be seeing error messages that include either 10.3 or 10.4 in them.

Update: So it seems you do have an easy_install installed for the extra python.org or at least for whatever version of Python is pointed to by /Library/Frameworks/Python.framework/Versions/Current. You seem to have to have two separate problems here (with the Python 2.5 and another with the system Python 2.6). At this point, it is difficult for me to guess what either of the problems is without getting a lot more information. It is probably best to clean up and start over.

1. If you want to remove the old Python 2.5 carried over from your old system, you can follow the instructions here on how to remove a python.org installed Python. If you want to, you can make a copy of it first or rename it instead with something like:

   cd /Library/Frameworks/Python.framework/Versions
   sudo mv 2.5 2.5-OLD 
   

   Consider doing the same for any other Python version there. DO NOT delete or modify any files in /System/Library/Frameworks or /usr/bin. Those directories are part of OS X.

2. Make sure you clean up your shell profile files, .bash_profile etc, to ensure that your PATH no longer includes this Python. Make you don't have any unexpected PYTHONPATH environment variables defined.

3. Make sure you don't have any outdated Distutils configurations files in your home directory. Look for and rename or remove things like .pydistutils.cfg.

   cd ~
   ls -al
   

   Also make sure you don't have any unexpected private packages installed in local directories.

   ls -al ~/Library/Python
   ls -al ~/.local
   

4. Inspect and, if necessary, delete anything in the site-packages directories for the Apple-supplied Pythons:

   cd /Library/Python/2.6/site-packages
   ls -al
   cd /Library/Python/2.5/site-packages
   ls -al
   

5. Start a new terminal session and verify that all is well.

6. Decide what versions of Python you want to use with 10.6. If you are OK with using the Apple-suppled 2.6.1 or 2.5.4 versions, then use them. They both come with their own versions of easy_install in /usr/bin.

   -rwxr-xr-x  1 root  wheel  421 Jun 30  2009 /usr/bin/easy_install-2.6*
   

7. If you want more recent and up-to-date versions of Python, consider installing the latest Pythons (Python 2.7.2 is the current version of Python 2) from python.org or homebrew, MacPorts, Fink, ActiveState etc. Update your shell PATH as necessary. (For example, the python.org installers by default modify your shell profiles appropriately.)

8. If the installation doesn't already come with an easy_install (python.org doesn't, some of the others have an optional package to do so), install the Distribute package which will provide an easy_install for it.

Have you installed XCode? It looks like you haven't.
