Hi Jim and Clemen,
I really appreciate your support and time.
I'm newbie in python programming, so my idea was to have an easy
implementation of my wepapp using web2py + Rocket (it was an excelent
option for me until this issue with Rocket arised).
So, I have decided to leave Rocket out of the equation and try to move
into the Apache or Nginx configuration, which implies to include a little
more stuff,
so I hope to be able of migrating my webapp soon.
Just in case, if you found any solution for this Rocket issue with Python
3 in web2py, it will be welcome. I'm still convinced that Web2py + Rocket
is the best option for faster development of webapps in Python.
Regards,
Víctor.
