Can't install: AttributeError: 'NoneType' object has no attribute 'rfind'

[hellais]

This was reported on: https://github.com/dugsong/pypcap/issues/49.

There seem to be some reported fixes in there we could integrate into our setup.py

Also noticed this on macOS 10.12.1 (Sierra) and fixed it by installing dupes/libpcap with homebrew.

Here is the stacktrace of the error I was getting:

  Using cached pypcap-1.1.5.tar.gz
    Complete output from command python setup.py egg_info:

I believe this should be fixed in the current master. If you could check that is indeed the case this would be very useful.

I plan to anyways make a long due new release and push to pypi that should address this.

I have the same problem on ubuntu16.04,python 2.7 and i solve this problem by "apt-get install libpcap-dev"

Yes libpcap-dev is in fact a dependency of pypcap as is listed in the Readme. We should probably provide a better error message when this happens in the setup.py though. I filed an issue for that last thing here: https://github.com/pynetwork/pypcap/issues/51.

This fix is now shipped as part of 1.2.0
