pyramid - Syntax error in a Python library, and I'm not sure how to proceed -

i'm using pyramid 1.5.1 , python 3.2, , added quite bit of code , couple libraries project.

on running development.ini, i'm getting error below.

if had take wild guess, particular library (looks markupsafe?) isn't compatible python3...but project page seems indicate is. problem is, i'm not calling library directly, it's beingness used library hard replace.

i'm new python programming, , wondering options here or best way debug is?

the markupsafe bundle uses syntax supported python 3.3 , up. python 3.2 not supported anymore of version 0.16.

the u'unicode' literal syntax introduced in pep 414 create easier create library code can back upwards both python 2 , 3.

either upgrade python 3.3 (or 3.4 even), or downgrade markupsafe 0.15, lastly version back upwards python 3.2.

i see mako removes markupsafe dependency when using python 3.2; if nil else depends on perhaps safe remove bundle altogether. mako.filter source code fall local implementation if bundle not installed.
