No module named MySQLdb even if MySQL-python installed?

I have a CentOS box.

(venv)[root@localhost]# yum install MySQL-python

>>> import MySQLdb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

What do I do?

and when I try pip install mysql-python I get this:

    sys.exit(main())

You need to force pip to use the default localization settings. Instead of:

pip install mysql-python

do:

LC_ALL=C pip install mysql-python

If you run into an error: Python.h: No such file or directory, then you'll need to install an additional library:

yum install python-devel

Some times we need to externally add/install git repo, This is not released yet but you can add from below command

pip install git+https://github.com/PyMySQL/mysqlclient-python.git

And

pip install mysql-python

and

yum install python-devel
