Here is the code: https://gist.github.com/guyjacks/3b3ca07fa62bd679cca3

Installed packages: https://gist.github.com/guyjacks/8e582fcf5d19547dd729

Python version: 3.2.5 on Mac OSX.

Virtualenv is activated so its not that!

FYI, it works fine when using cpython 3.4.3.

Answer 1

The error message:

DEFAULT_ERROR_LOG_FORMAT = (u'{0:%Y-%m-%d %H:%M:%S} [FALCON] [ERROR]'
                                                                    ^
SyntaxError: invalid syntax

is pretty clear here. Python cannot make sense of the string.

The u'' syntax for strings is only supported for Python 2 and Python >= 3.3. Python 3.2 is really old. You need to upgrade your Python version. If possible, I would recommend to switch to Python 3.5 right away.
