I have a windows 10 PC.
I installed c:\python27 and c:\python3 and they are working. I can choose.
But if I try to start web2py it happens this error:
c:\Python3>python.exe c:\web2py\web2py.py
Traceback (most recent call last):
File "c:\web2py\web2py.py", line 21, in <module>

from cgi import escape
ImportError: cannot import name 'escape' from 'cgi' (c:\Python3\lib\cgi.py)
I found that changing "from cgi import escape" to "from html import escape"
it start but I don't knoy why.
Nevertheless If I try to start an app built from Python27 I have this error:
<type 'exceptions.RuntimeError'> Failure to connect, tried 5 times:

If I start the same app with web2py on python 2.7 changing back to "from
cgi import escape" and it's working.
Maybe this is a problem regarding foreign-keys, I had one time in the past
but.... really... I don't remember how to fix.
Thank you
