This is not the problem. The problem is that web2py calls json.dumps(...,
default=....)
This API is supported by both json and by simplejson (which ships with
web2py). The problem is that you have another version of simplejson
installed. An older version that does not support this API.
You should uninstall is
pip uninstall simplejson
The web2py change was motivated by this:
http://stackoverflow.com/questions/712791/what-are-the-differences-between-json-and-simplejson-python-modules
because people usually install simplejson to have a newer version of json,
not an older version. ;-)
