I have two pure python projects in PyCharm 3.4.1 Professional Edition. The first one, let's call it p
(like package), is structured as a setuptools package (i.e. with setup.py, all requirements etc., however it is not uploaded to pypi or any other online repository). The second one, let's call it s
(like script), is just a python script along with two modules.
Project s
is (in PyCharm) configured to use a dedicated virtualenv, let's call it venv
.
The problem I have is the following: when I install the project (package) p
in venv
like this:
$ source /path/to/venv/bin/activate
(venv)$ cd /path/to/p
(venv)$ python3 setup.py develop
in PyCharm in project s
, import p
statements are errorneous with message No module named p. However, when I run the script in s
, everything is fine, the only problem is the PyCharm IDE complaining about not being able to find the module. I can live with this but it is very annoying...
Why does this happen? Is it a PyCharm thing or packaging related thing? See NEWS below.
The project/package p
has the following structure:
p/
|
+- p/
| |
| +- __init__.py
| +- other subpackages, modules, etc.
+- setup.py
+- README, DESCRIPTION, setup.cfg, etc.
When I configure the PyCharm project p
to live in its own virtualenv and install it there in development mode, everything works fine.

This problem is still present in PyCharm 5.0.4. However, I managed to solve it, kind-of.
For some reasons I had to install another package from pypi. I did it through PyCharm by going to File -> Settings -> Project: -> Project Interpreter, there clicking on the green +
, finding the package and pressing the Install Package button. After the installation, the package installed by python3 setup.py develop
is well recognized by PyCharm. Obviously the problem was that PyCharm didn't have some cache in sync with reality.
So the new question is, can PyCharm be told to update its caches regarding the used python environment?
