I've been using PyCharm CE with pretty great success. But I just installed the basemap module (having to compile geos and basemap from source) and it seems to have broken the PyCharm interpreter. All of my modules load properly when I run Python from the terminal, and all of my modules run properly when I run Python from the terminal WITHIN PyCharm, but now when I attempt to load certain packages from the interactive interpreter, I get error messages. For example, now when I try to import pandas in the interactive interpreter, I get this:

Traceback (most recent call last):

path = sys.modules[parent].__path__
KeyError: 'dap'

If I try to import pandas again, in the same session, the error message changes to this:

Traceback (most recent call last):
cannot import name hashtable
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-    packages/IPython/core/interactiveshell.py", line 2827, in run_code

import pandas as pd
File "/Library/Python/2.7/site-packages/pandas/__init__.py", line 6, in <module>
from . import hashtable, tslib, lib
ImportError: cannot import name hashtable

What did I do to break the interpreter? I tried reinstalling PyCharm to reset and it didn't seem to work.

I case this helps anyone. I had this issue in a Django project that also was setup to use Google App Engine; therefore, PyCharm loaded the GAE version of many Python packages (they were being added to my PYTHONPATH). I disabled Google App Engine support in File -> Settings -> Languages & Frameworks -> Google App Engine. The problem went away.

Note: I did not have the Pandas import issue when running my Django app outside of PyCharm.
