On my current project, im using Python, Django and Pip. But there is some issue when installing libraries needed for running the app,

pip install -r requirements.txt

Below is the error generated when running it,

_mysql.c:29:10: fatal error: 'my_config.h' file not found
   #include "my_config.h"
            ^~~~~~~~~~~~~

   error: command 'clang' failed with exit status 1

 Rolling back uninstall of mysqlclient

Looks like error happen when trying to install below library,

mysqlclient==1.3.7

Below is Python and Pip version that im using,

 
$ python --version
Python 3.4.3

$ pip -V
pip 18.1 from /Users/m/.pyenv/versions/3.4.3/envs/logistic_backend/lib/python3.4/site-packages/pip (python 3.4)

The main culprit is corresponding library is not supported by Python 3.4.3, changing it into below lib fix the error

pymysql==0.9.2
