Ubuntu – How to install regex package for python 3.4 without errors

pythonregex

I have a little problem (or a big one?). I want to install regex package
for Python 3.4. But then I use pip or our installation methods I am getting error: 

universe@universe-AOD270:~/Downloads/regex-2016.04.25$ python setup.py

****Python2/_regex.c:46:20: fatal error: Python.h: No such file or directory
compilation terminated.****
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

I think that this problem arise because installer try to install this package into Python2.7 directory, but I am not sure. I try pip installation, launch from interpreter of Python, running through terminal, but have no success.
Please, help me to solve this problem. Thanks in advance.

I also struggle with this error, then I found the python3-dev is missing but when I run the command it's already installed. Then I check for which python version it is installed using below command - 

sudo find / -name "Python.h"

and output is like - 

python2.7/Python.h
python3.5/Python.h

So then I check the version of python I am running to install that package using below command

python3 -V

Output - 

Python 3.6.7

So to install python3-dev use below command

sudo apt-get install python3.6-dev

Just replace it with your python3 or python2 version
