InstallationIssue, Trac 1.4.x doesn't support Python 3. Please install into Python 2.7 or use 1.5.3 pre-release:

$ pip install https://download.edgewall.org/trac/Trac-1.5.3-py3-none-any.whl

[Ryan J Ollos]

Regarding except TypeError, e reported as "invalid syntax", you must have a old version installed since Trac 1.4.x uses except TracError as e syntax.

Should be limitation to install under < python 3.0
