Answer 1

This isn't an error, just a warning (hence UserWarning ) and has to do with the way that you've installed Autobahn. It appears to me that you installed it with sudo pip install , which you should pretty much never do; instead sudo apt-get install or pip install things into a virtualenv .

In any case, it's harmless and you can ignore it.
