[python] No module named MySQLdb

I am using Python version 2.5.4 and install MySQL version 5.0 and Django. Django is working fine with Python, but not MySQL. I am using it in Windows Vista.

None of the above worked for me on an Ubuntu 18.04 fresh install via docker image.

The following solved it for me:

apt-get install holland python3-mysqldb

Ubuntu:

sudo apt-get install python-mysqldb

pip install --user mysqlclient 

above works for me like charm for me.I go the error from sqlalchemy actually. Environment information :

Python : 3.6, Ubuntu : 16.04,conda 4.6.8

Thanks to derevo but I think there's another good way for doing this:

1. Download and install ActivePython
2. Open Command Prompt
3. Type pypm install mysql-python
4. Read the notes specific to this package.

I think pypm is more powerful and reliable than easy_install.

for window :

pip install mysqlclient pymysql

then:

import pymysql pymysql.install_as_MySQLdb()

for python 3 Ubuntu

sudo apt-get install -y python3-mysqldb

Try this.

pip install MySQL-python

For anyone coming to this page when trying to find a solution for sqlalchemy, all you need to do is:

pip install PyMySQL

And adjust your connection string to use PyMySQL, from mysql:// to mysql+pymysql://.

On my mac running Catalina v10.15.2, I had the following MySQLdb version conflict:

ImportError: this is MySQLdb version (1, 2, 5, 'final', 1), but _mysql is version (1, 4, 6, 'final', 0)

To resolve it, I did the following:

pip uninstall MySQL-python
pip install MySQL-python

Win10 / Python27 this worked for me:

easy_install mysql-python

all other 'pip install...' failed with dependency errors

For Python 3.6+ sudo apt-get install libmysqlclient-dev and pip3 install mysqlclient does the trick

For Python 3+ version

install mysql-connector as:

pip3 install mysql-connector 

Sample Python DB connection code:

import mysql.connector
db_connection = mysql.connector.connect(
  host="localhost",
  user="root",
  passwd=""
)
print(db_connection)

Output:

> <mysql.connector.connection.MySQLConnection object at > 0x000002338A4C6B00>

This means, database is correctly connected.

mysqldb is a module for Python that doesn't come pre-installed or with Django. You can download mysqldb here.

Note this is not tested for python 3.x

In CMD

pip install wheel
pip install pymysql

in settings.py

import pymysql
pymysql.install_as_MySQLdb()

It worked with me

On Debian Buster, the following solution worked for me with python 3.7:

sudo apt-get install libmysqlclient-dev
sudo apt-get install libssl-dev
pip install mysqlclient

I have tried methods above, but still no module named 'MySQLdb', finally, I succeed with

easy_install mysql-python

my env is unbuntu 14.04

If you are running on Vista, you may want to check out the Bitnami Django stack. It is an all-in-one stack of Apache, Python, MySQL, etc. packaged with Bitrock crossplatform installers to make it really easy to get started. It runs on Windows, Mac and Linux. Oh, and is completely free :)

pip install PyMySQL

and then add this two lines to your Project/Project/init.py

import pymysql
pymysql.install_as_MySQLdb()

Works on WIN and python 3.3+

...and remember there is no MySQLdb for python3.x

(I know the question is about python2.x but google rates this post quite high)

EDIT: As stated in the comments, there's a MySQLdb's fork that adds Python 3 support: github.com/PyMySQL/mysqlclient-python

I met the same situation under windows, and searched for the solution.

Seeing this post Install mysql-python (Windows).

It points out installing such a pip environment is difficult, needs many other dependencies.

But I finally know that if we use mysqlclient with a version down to 1.3.4, it don't need that requirements any more, so try:

pip install mysqlclient==1.3.4

pip install PyMySQL

and then add this two lines to your Project/Project/init.py

import pymysql
pymysql.install_as_MySQLdb()

Works on WIN and python 3.3+

If pip install mysqlclient produces an error and you use Ubuntu, try:

sudo apt-get install -y python-dev libmysqlclient-dev && sudo pip install mysqlclient

If your are using SQLAlchemy and the error is in /site-packages/sqlalchemy/dialects/mysql/mysqldb.py:

from ...connectors.mysqldb import (
                        MySQLDBExecutionContext,
                        MySQLDBCompiler,
                        MySQLDBIdentifierPreparer,
                        MySQLDBConnector
                    )

so you may have missed mysqldb connector for SQLAlchemy and the solution is to re-install sqlalchemy after installing mysql-python module.

You need to use one of the following commands. Which one depends on what OS and software you have and use.

1. easy_install mysql-python (mix os)
2. pip install mysql-python (mix os/ python 2)
3. pip install mysqlclient (mix os/ python 3)
4. apt-get install python-mysqldb (Linux Ubuntu, ...)
5. cd /usr/ports/databases/py-MySQLdb && make install clean (FreeBSD)
6. yum install MySQL-python (Linux Fedora, CentOS ...)

For Windows, see this answer: Install mysql-python (Windows)

I personally recommend using pymysql instead of using the genuine MySQL connector, which provides you with a platform independent interface and could be installed through pip.

And you could edit the SQLAlchemy URL schema like this: mysql+pymysql://username:passwd@host/database
