Error during installation on Mac OSX with pip

[FlavienMakesInfographics]

Hi,

I tried to install the extension from pip on Mac OSX (Python 3):

PetitLepton @ ~/projects
 pip install jupyter_cms 
Collecting jupyter-cms
  Using cached jupyter_cms-0.4.0.tar.gz
    Complete output from command python setup.py egg_info:
    error in jupyter_cms setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers; Invalid requirement, parse error at "'<3.0'"

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/23/mxzcl9h95zzfwbfp74wn5h340000gn/T/pip-build-q2v2gbmo/jupyter-cms/

It is using cached because I tried several times. I played with the setup.py and got rid of <3.0 and the installation went through (pip install -e ...) but then, when searching, nothing happens so I am not sure it installed the extension properly.

Thank you for this, by the way, it is super useful.

What version of pip are you running?

The same

PetitLepton @ ~
 pip --version
pip 8.1.1 from /usr/local/lib/python3.5/site-packages (python 3.5)

Yeesh. Maybe shell whitespace setting difference? Can you try taking the space out of the version # on this line https://github.com/jupyter-incubator/contentmanagement/blob/master/setup.py#L17 and see if it installs without other changes?

[FlavienMakesInfographics]

Indeed, without the space before <3.0, it works.

I :heart: shell settings. Thanks for reporting and testing. If you'd like to do the honors on a PR fixing the two spaces in the setup.py, that'd be great. Otherwise, I'll get to it soonish.

I will let you do it, I am more than a newbie on git/github. Again, thanks for the good work!

[parente]

No prob. Cheers!
