Can't exclude packages in develop mode

[tchittesh]

Suppose we have the following file structure.

.
├── badmodule
│   └── __init__.py
├── goodmodule
│   └── __init__.py
└── setup.py

with setup.py containing

from setuptools import setup, find_packages

setup(
        name = 'bug',
        packages=find_packages(exclude=('badmodule')),
)

It seems that running pip install -e . also installs the undesired badmodule. (Running import badmodule works in a Python interpreter from any directory.)

However, if we do a proper non-develop mode install, these excluded modules are actually not installed.

Any idea what's going on?

That's just how an editable install work: your project source directory is added to the Python path. And yes, it means that setup.py is importable too...
