Where can I find Python.h file and how do I fix this problem under Debian or Ubuntu Linux sever based system?

Python.h is nothing but a header file. It is used by gcc to build applications. You need to install a package called python-dev. This package includes header files, a static library and development tools for building Python modules, extending the Python interpreter or embedding Python in applications. To install this package, enter:
$ sudo apt-get install python-dev
OR
# apt-get install python-dev

    Thanks for this! Also I had to

    rm -rf ~/build

    To get it to work again – because the previous results had been cached!

    That saved me :) Thanks!

    In my case (building pyskein) I needed the python3-dev package.

    • Kunal February 1, 2015, 10:14 am

      Thanks for the tip on the python3 bit. I was running the command listed on and linux was telling me everything was up to date.

    fatal error: Python.h: No such file or directory
    compilation terminated.

    …:(

    • Kamil March 30, 2014, 3:10 pm

      Are you using Python3? If so, you have to install python3-dev package.

      • Kunal February 1, 2015, 10:15 am

        Yeah you have to use python3-dev

        sudo apt-get install python3-dev
