I wanted to install Eventlet on my system in order to have "Herd" for software deployment, but the terminal is showing a GCC error (as root):
cd ~
easy_install -U eventlet

Why can't Python.h be found?
Your install is failing because you don't have the Python development headers installed.
First, update the packages with sudo apt update.
You can do this through APT on Ubuntu/Debian with:
sudo apt-get install python-dev
For Python 3, use:
sudo apt-get install python3-dev
For eventlet you might also need the libevent libraries installed so if you get an error talking about that you can install libevent with:
sudo apt-get install libevent-dev
