Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-Ah8Cmq/pymatbridge/

I am posting this for reference in case someone else encounters the same issue

I am freshly setting up a virtualenv for development (github master version, my OS is fedora) and I did
pip install --upgrade pip
pip install -r develop-requirements.txt

I got this error:

Collecting pymatbridge (from -r develop-requirements.txt (line 11))
  Using cached pymatbridge-0.5.2.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-TmZKMy/pymatbridge/

after a few unsuccessful web searches I got it working by doing

pip install zmq
pip install numpy
pip install -r develop-requirements.txt


no idea why!

cheers

Got error Could not open requirements file: [Errno 2] No such file or directory: 'develop-requirements.txt' when executing pip install -r develop-requirements.txt. I nevrtheless proceeded with pip install cobra[all].
Worked like a charm after that! Thank you Antonella. :)
