Long story short, when I write the following:
sudo easy_install MySQL-python
I get the error
EnvironmentError: mysql
Above all, I can't solve it. But I add file to /usr/local/include solve it.
https://github.com/peterlee0304/MySQL-Python/blob/master/my_config.h
In /usr/local/include, add a my_config.h file.
Then pip install MySQL-Python
Solve it!
