IntelliJ Python plugin & Run classpath

Question

I have a project located at /home/myself/workspace/Project1, for which I created an SDK from a Python 2.7.3 Virtualenv I have setup.
This project uses some external code that I have in an accessible directory, e.g. /home/myself/LIBRARY; this directory contains several directories with code, docs etc....
For example, there is a module "important_util" located at /home/myself/LIBRARY/mymodule/important_util.py.

Now, I added the whole dir /home/myself/LIBRARY in the SDK Classpath, and in the Editor window it appears just fine. The imports and calls are recognized and I can also navigate through the code in LIBRARY directories.

The problem is that, when I try to run my program, it fails at the first import using LIBRARY!!!

Traceback (most recent call last):    File "/home/myself/workspace/Project1/my_program.py", line 10, in <module>       from mymodule import important_util as ut        ImportError: No module named mymodule 

I also tried to add the same directories to the section "Global Libraries" in the Sources section...but no luck.

I can't seem to find a way to add this code to the Run classpath, how would I be able to do this?

Answer 1

Make sure you have __init__.py in mymodule directory:

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path. In the simplest case, __init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable, described later. ©

UPDATE: In IntelliJ IDEA additional directories should be added as Module Dependencies or configured as Libraries (to be added to the Dependencies) instead of the Classpath tab of the Python SDK:

I've verified that this folder (D:\dev\lib) is added to the PYTHONPATH and import works.

In IntelliJ 14 it's a little different, you are modules/eggs like so:

• Go to File -> Project Structure
• Now select Modules and then "Dependencies" tab
• Click the "+" icon and select "Library"
• Click "New Library" and select Java (I know it's weird...)
• Now choose multiple modules / egg and "OK".
• Select "Classes" from categories.
• Give your new library a name, "My Python not Java Library"
• And finally click "Add Selected"
