Error message "error: command 'gcc' failed with exit status 1" while installing eventlet


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?


Solution

  • 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
