py2app不包括pythonpath

Question

I'm trying to build an app with py2app. I can build the app but when I run it I get ImportError in the console, the import error is that there is No module named PythonApp which is the folder all my source is in, the location of which is in my PYTHONPATH .

I have been importing local files like from PythonApp import file instead of just import file to help avoid namespace issues.

I have tried to build it with the following flag python setup.py py2app --use-pythonpath but this hasn't appeared to make any difference.

• Should I just change the import statements throughout to import file ?
• How can I make py2app realise my PYTHONPATH ?

If I understood your problem well, you have the following layout:

PythonApp/
  __init__.py
  file.py
  foo.py

And you try to import the module file from foo.py by from PythonApp import file . If this the only reason you want to set PYTHONPATH , there is a simpler solution: use relative imports :

from . import file

You can use from .. import file in a sub-package of PythonApp , and so on. This way you can avoid name collisions with standard modules.

If you need to hack the import path for some other reasons, you can also set the sys.path variable in the startup script (probably py2app has some options for that, too). Keep in mind though that if you add external directories into the import path, it will be harder to distribute the app bundle.

Also, a more trivial explanation for the ImportError is that py2app did not copy your package into the app bundle. Make sure you have all your packages listed in the packages parameter of setup() .
