i have tried installing mysqldb by commands

pip install MySQL-python

then i am getting below error

    (env1)shiv@shiv-Calpella:~/Project/Poll_app/mysite$ pip install MySQL-pythonCollecting MySQL-python

    ----------------------------------------
    Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-3FRYWs/MySQL-python

my setting.py file is

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql', 
        'NAME': 'poll_db',                     
        'USER': 'root',
        'PASSWORD': 'root',
    }
}

`Command "python setup.py egg_info" failed with error code 1` is not the real error message here. Look above this line for the actual error and add it to your question please. — Lukas Graf, Mar 14 '15 at 13:45

@ShivDangi thank you. So the actual error is `EnvironmentError: mysql_config not found`. Which means `mysql_config` can't be found in your path, and the installation of `MySQL-python` fails because of that. The question I linked as a duplicate should help you to resolve this (as should @WojciechPolak's answer). — Lukas Graf, Mar 14 '15 at 13:57

In the above example, the answer might be in the proper log file pip.log or somewhere in /tmp/pip-build-rHe_Sb/MySQL-python.

1) When installing MySQL module with PIP, please make sure you have installed for instance the mysql-devel (yum) or libmysqlclient-dev (apt-get) package in your system.

2) BTW, I would recommend mysqlclient ($ pip install mysqlclient) instead of MySQL-python, as it supports both Python 2 and 3.x.

You have 2 options, as described bellow:

Distribution package are-:

sudo apt-get install python-mysqldb

In this case you can't use virtualenv no-site-packages (default option) but must use:

virtualenv --system-site-packages myenv

Use clean virtualenv and build your own python-mysql package.

First create virtualenv:

virtualenv myvirtualenv

source myvirtualenv/bin/activate

Then install build dependencies:

sudo apt-get build-dep python-mysqldb

Now you can install python-mysql

pip install mysql-python

NOTE Ubuntu package is python-mysqldb , python pypi package is python-mysql (without db)
