Can't find "Python.h" file while installing Watchman

Question

I use Linux Mint 17 'Quiana' and I want to install Watchman to use later Ember.js. Here were my steps:

$ git clone https://github.com/facebook/watchman.git

then

$ cd watchman
$ ./autogen.sh
$ ./configure.sh

and, when I ran make to compile files, it returned the following error:

pywatchman/bser.c:31:20: fatal error: Python.h: no such file or directory
#include <Python.h>
                ^
compilation terminated.
error: command 'i686-linux-gnu-gcc' failed with exit status 1
make[1]: *** [py-build] Error 1
make[1]: Leaving the directory `/home/alex/watchman'
make: *** [all] Error 2

I tried to run

$ sudo apt-get install python3-dev

but it appears to be already in my system. What have I done wrong?

Usually its the python-dev libs missing. Are you sure the configure uses the python 3 instead of python 2? Because if thats the case you should install `python-dev` instead of `python3-dev`. @NilsWerner python3-dev should install `libpython3-dev` as dependency. — Tomax, May 18 '16 at 11:00
Well if it does my guess would also be a Python 2/3 configuration problem. — Nils Werner, May 18 '16 at 11:03
@Tomax, so you were right, that was the problem - I had to install python 2 `dev`, now it works. thanks! — AlexNikolaev94, May 18 '16 at 11:06
Thanks @AlexNikolaev94, give it the answer status so it can help others with same or similar problems to yours. — Tomax, May 18 '16 at 11:08
@AlexNikolaev94 After reading the meta, I guess I shall put the comment as answer and you acknowledge it.. I'm kinda new in here... :) — Tomax, May 18 '16 at 11:20
@AlexNikolaev94 `sudo apt-get install python-dev` solved my problem. Try it. — Santanu, Sep 16 '16 at 15:56

On Fedora 24 you need `sudo dnf install python-devel`. – 0skar Dec 23 '16 at 16:37

Same problem if you build watchman under rasbian/raspberry. Install "python-dev".

git clone https://github.com/facebook/watchman.git
cd watchman
./autogen.sh
./configure
make

sudo make install
