Scapy on Mavericks via Homebrew "AttributeError: 'module' object has no attribute 'intf'"

I tried to install Scapy on OS X via Homebrew which seemed to work fine.
After installation there were some Python modules missing which I installed via Homebrew.

Now when I start Scapy I get the following error:

INFO: Can't import python gnuplot wrapper . Won't be able to plot.

Anyone with some ideas?

Solution 1:

I seem to have fixed this issue for myself, I think it's due to a corrupt/buggy "egg" file. I cannot guarantee this will work for you, but I've had this problem for the last 2 months, word for word. And now, I can at least get into scapy.

First of all, I found my Python install's paths, with this command:

python -c "import sys; print sys.path"

In my case, the first few paths were various .egg files. Try removing the pydnet egg, which in my case is called PyDNET-0.92-py2.7.egg. I haven't really tested it too much at this point, but scapy boots, at least. So we know where the problem must be.
