Web.py / No module named 'utils'`

Question

I'm trying to install web.py, and I did the next steps:

• Download web.py-0.3.7, and extract it on c://web.py-0.3.7

• Run the next command:C:\>python C:\web.py-0.37\setup.py install

• and it gives me the next error: import utils, db, net, wsgi, http, webapi, httpserver, debugerror ImportError: No module named 'utils'

How can I install and use web.py?
