Problems getting Falcon to run on Mac

Question

I'm having a challenge running Falcon on my Mac. I'm using python 2.7 along with pycharm for some time with no issues.

There seems to be several related posts here , here, and here, but still seem to have the same problem.

I've spent many hours trying to get this to work and everything appears to point to the six package and SSL.

Following are my efforts so far. Any help greatly appreciated

You may have a problem with your environment. I use Mac and I never had a problem. To make sure, try to use virtualenv.

pip install virtualenv
virtualenv test
source ./test/bin/activate
pip install falcon
pip install gunicorn
cd go/to/your/falcon/app/path
gunicorn things:app

If it's doesnt work, try reinstalling pip. Let me know if it works.

Running the command:

$ pip install falcon

will install falcon version 0.3.0 which gives error: ImportError: No module named http_cookies

Install falcon using package from python.org

Then install package like so:

$ pip install falcon-1.0.0rc1.tar.gz
