Is there a step that I am missing to make my chrome binary available to my app?

I'm trying to run MkDocs and getting a StopIteration error when running mkdocs serve. This is on a fresh MkDocs project. I've installed MkDocs, ran mkdocs new my-project and then mkdocs serve.
It appears the file_match variable is empty on line 345 of config_options.py but I can't figure out what populates file_match. Is there an additional step between installing MkDocs and then using it that I'm missing?
Thanks for any help. My full stack trace is below.

How do I fix this ?
Thank to Martijn, I have fixed this.
In the source, stable 2.2 branch line 146 of django/db/backends/mysql/operations.py is
query = query.decode(errors='replace')
In my system path/to/virtualenv/django/db/backends/mysql/operations.py was like
# query = query.decode(errors='replace')
query = query.encode(errors='replace')
I changed it to
query = query.decode(errors='replace')
# query = query.encode(errors='replace')
It is working correctly now.

However, if I went into Djangon's shell interactive environment and wrote directly into the database, everything went smoothly. I don't why this problem happens.
This issue seems to exist in OS X with python 2.7.10 and according to the link below, you will most likely run into this with CentOS 7 and Python ver 2.7.9 or above.
https://github.com/gevent/gevent/issues/477
Updating gevent to 1.2.1 seems to solve the problem.
You could run "pip install --upgrade gevent" on mac to fix this.
Installing readthedocs locally following the guidelines from the http://read-the-docs.readthedocs.io/en/latest/install.html fails. I'm attempting to install it on a Mac Pro OSX El Capitan 10.11.15.

i have a big problem with Mercurial 1.8.2 on Mac OSX 10.6
I used for long time with a lot of projects. Now i haven't used for about 4 weeks. Today i tried and OSX crashed with "hg add" command.
So i googled a little bit and found out, that there was a bug in OSX 10.5 where i have to deactive the SET LOCAL in Terminal Preferences.
I've done so - now
hg add
hg commit -m "message"
works, but when i run
hg push
i get the following error message where i find no information about
