Namespace package breaks module imports #895
Description
Here's a simple example to reproduce the problem. In https://github.com/matham/pip-nspace-broken there's a farm package as well as a farm.deps.glew meant to share a namespace with the farm package.
Also included are the wheels built with it. After installing the wheels with pip, I get the following:
$ python
Python 3.4.4 (v3.4.4:737efcadf5a6, Dec 20 2015, 20:20:57) [MSC v.1600 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from farm import my_name
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name 'my_name'If I remove farm.deps.glew I get the following:
$ python
Python 3.4.4 (v3.4.4:737efcadf5a6, Dec 20 2015, 20:20:57) [MSC v.1600 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from farm import my_name
Imported farmThis is with pip 9.0.1.
So basically, having a namespace package seems to break the main package.
