Python.h missing from Ubuntu 12.04

Question

I installed an openflow controller on my Ubuntu 12.04 called RYU using:

 sudo  pip install ryu

I was trying to run a python file using ryu-ma

Answer 1

Install gevent directly - sudo apt-get install python-gevent.

Answer 2

Even if you have Python installed, the header file and the library usually aren't installed by default. On Ubuntu, they come in a separate package called python-dev.

Answer 3

hey community i solved this problem by this command

pip3 install -U git+https://github.com/kti/python-netfilterqueue

hope it works :)

Answer 4

This should do it:

sudo apt-get update; sudo apt-get install python-dev -y

It will install any missing headers. It helped me a lot.
