Add support of twisted framework, or possible error is climbing inheritance hierarchy

[akshetpandey]

For this code:

from twisted.internet.protocol import DatagramProtocol

class Class(DatagramProtocol):
    def __init__(self, string, host, port):
        self.transport.write(string, (host, port))

The inspector gives an error that class Class has no method transport. Whereas transport is defined by AbstractDatagramProtocol which is inherited by DatagramProtocol

I'm not able to reproduce this issue. What versions of twisted, pylint, and prospector do you have installed?

I am seeing the issue while using landscape. See this url,

I think @carlio will need to chime in on this one. I think the problem lies with the environment that Landscape is running prospector in. When twisted is installed, that message doesn't come up. But when run in an environment without twisted, pylint reports that error.

Thanks for looking into it @jayclassless - you're right, it's about how Landscape runs prospector rather than anything else. Currently, it does not install dependencies of your library, so it will find errors that prospector will not find if you run it locally in your environment which does have the dependencies installed.

I'll close this, as it's not a prospector issue, but rather a landscape issue. I've also opened landscapeio/landscape-issues#31 to keep track of the improvement in Landscape behaviour.
