Pycharm问题-ImportError：没有名为appengine.datastore.datastore_query的模块

Question

I have been trying to use the excellent project located at http://docs.gae-init.appspot.com/ , in order to learn python, GAE and perhaps start my own hobby project. My IDE of choice is Pycharm 3.4 Professional Edition. Operating system is OSX Mavericks.

I have been trying to follow the tutorial, therefore I have git cloned the project at a local directory and subsequently opened in into Pycharm. I believe I have managed to resolve the majority of requirements (PyCharm helps a lot).

Nevertheless, when trying to Run the project I get the following error:

  File "/Users/nilminus/Developer/phonebook/main/main.py", line 9, in <module>
    import util
  File "/Users/nilminus/Developer/phonebook/main/util.py", line 10, in <module>
    from google.appengine.datastore.datastore_query import Cursor
ImportError: No module named appengine.datastore.datastore_query

I have configured GAE directory as /usr/local/google_appengine which is correct. Pycharm does not complain about not finding this module before actually executing it. There is a warning that module google is not listed in requirements.txt, but it does not makes sense to me that this could be the issue.

I have included PYTHONPATH in .profile and ~/.bash_profile: PYTHONPATH=/usr/local/google_appengine/:/usr/local/google_appengine/lib/:/usr/local/google_appengine/lib/yaml/

The funny thing is that if I upload this exact project in GAE, it works perfectly. Also, if I run this project with ./run.py -s (as exhibited by its author), it works again. Even ./dev_appserver.py main/ works.

This issue has truely dazzled me that last week. Any help is highly appreciated.

When creating Google Engine App project, specify App Engine SDK path in App Engine SDK directory field:

Note: PyCharm automatically detects the GAE installation path, and displays it in this field. However, Auto-detection works for Windows and OS X. For Linux, you have to specify the App Engine SDK yourself.

Also specify SDK path in Settings
