The above shows a successful run of scapy with all dependencies correctly installed. Scapy is a powerful Python-based interactive packet manipulation program and library. (If using python 2.7): $ pip install pyx=0.12.1 -I –no-cache …”, see step 8 below to fix dependencies. If you get errors like “INFO: Can’t import packageXYZ. Step 5: At this point, if everything worked correctly, the output of ` which python` and ` which pip`should yield /usr/local/bin/python and /usr/local/bin/pip respectively Step 4: Force updates to PATH variable by using source:

(add the above line at the end of your ~/.bashrc or ~/.zshrc, whichever shell you are using)

Step 0: Check existing python version by the command ` which python`. Packet generator/sniffer and network scanner/discovery (Python 3) Scapy is a powerful interactive packet manipulation tool, packet generator, network scanner, network discovery, packet sniffer, etc. Having run into a lot of problems with installing and using scapy and other packages with the correct version of python, pip and homebrew in the mix, I decided to write steps that anyone can follow to setup a clean and working python environment in OSX without running it in a virtual environment or fiddling with the default python installation.
