    Hello PyDEV users

    === Environment ===
    I installed PyDEV extensions 1.3.13 to Eclipse 3.3.1.1 on my Mac. Its OS was clean-installed recently from Tiger to Leopard. And I have copied ~/Document/workspace from old HDD to new HDD.

    === Problem ===
    I have some python projects which were developed on the previous Tiger environment. They were working as I expected with PyDEV extension. However after installing new OS X Leopard, Code Analysis outputs many errors to my python scripts.

    For example,

    import time
    => Unresolved import: time

    class MyClass(object)
    => Undefined variable: object

    foo = None
    => Undefined variable: None

    of course these lines run correctly on my Mac (python 2.5.1).

    import sys
    does not output an error. But sys.stderr and sys.exit are said that "Undefined".

    I tried
    - Reinstalling PyDEV
    - Reinstalling Eclipse
    - Removing ~/Documents/workspace/.metadata/.plugins/org.python.pydev*

    but I still get the above errors.

    Anyone know how to remove this problem? Any suggestion?

    I am not sure if this problem was caused by Leopard.

      That means that your builtins are not currently correctly gotten. Please check:
      - do you have something in your error log?
      - do you have some firewall enabled that may be blocking communication? (the builtins are gotten by spawning a python shell and communicating with it through sockets to get those tokens)
      - is your interpreter correctly configured?

      Hello Fabio

      Thank you very much for your quick reply. It works now.

      >- do you have something in your error log?

      I found four same errors which was

      The interpreter location found does not exist. /Library/Frameworks/Python.framework/Versions/2.5/Resources/Python.app/Contents/MacOS/Python

      This seems the path defined in the previous OS. The default version of python is 2.3 in OS X Tiger so I installed 2.5 under /Library . I changed this to

      /System/Library/Frameworks/Python.framework/Versions/2.5/Resources/Python.app/Contents/MacOS/Python

      from the preference menu. This is the default path in OS X Leopard. I do not know which file contains this path info but new OS X Leopard users are recommended to check this item if one has same problem.
