Looks good. Could you make a PR for this ?
Thanks !

@trbs sure thing, PR @ #1170

@trbs the fix #1170 only work if i install django-extensions with pip --no-binary, I other words, when I force pip do not use the whell package

pip install django-extensions -U --no-binary :all:

my environment

Python 2.7.11 (default, Mar  8 2016, 09:32:11) 
[GCC 5.2.1 20151010] on linux2
Type "help", "copyright", "credits" or "license" for more information.

I've looked for some way to fix this, but I'm still a bit confused as to the correct way to do this

The closest I found it was

https://hynek.me/articles/conditional-python-dependencies/

@hynek do you have any comments on what is the current correct way to specify conditional dependencies in a way to work with a wheel package?

@tdruez Hey man, maybe I am misreading how the setup.py works, but it seems to me like you are currently installing typing only if the Python Version is smaller than 3.5.

@s-wirth the typing module was included in the standard library in Python 3.5, so it is not necessary to install it in python 3.5 or higher, because it is already installed

@luzfcb Ah yeah that makes sense. Thank you for the answer :)

@luzfcb the most correct way is currently PEP 508 but the most compatible way appears to be the using extras_require. It strictly depends on how old pip/setuptools you want to support.

Please test with Django Extensions 2.0.5 and hopefully that fixes the issues.

If there other (edge) cases where it still fails please reopen the issue.
