Question 1

How can I install the MySQLdb module for Python using pip?

Question 2

It’s easy to do, but hard to remember the correct spelling:

pip install mysqlclient

If you need 1.2.x versions (legacy Python only), use pip install MySQL-python

Note: Some dependencies might have to be in place when running the above command. Some hints on how to install these on various platforms:

Ubuntu 14, Ubuntu 16, Debian 8.6 (jessie)

sudo apt-get install python-pip python-dev libmysqlclient-dev

Fedora 24:

sudo dnf install python python-devel mysql-devel redhat-rpm-config gcc

Mac OS

brew install mysql-connector-c

if that fails, try

brew install mysql

Question 3

Starting from a fresh Ubuntu 14.04.2 system, these two commands were needed:

 apt-get install python-dev libmysqlclient-dev
 pip install MySQL-python

Just doing the “pip install” by itself did not work.

From http://codeinthehole.com/writing/how-to-set-up-mysql-for-python-on-ubuntu/

Question 4

First

pip install pymysql

Then put the code below into __init__.py (projectname/__init__.py)

import pymysql
pymysql.install_as_MySQLdb()

My environment is (python3.5, django1.10) and this solution works for me!

Hope this helps!!

Question 5

I had problems installing the 64-bit version of MySQLdb on Windows via Pip (problem compiling sources) [32bit version installed ok]. Managed to install the compiled MySQLdb from the .whl file available from http://www.lfd.uci.edu/~gohlke/pythonlibs/

The .whl file can then be installed via pip as document in https://pip.pypa.io/en/latest/user_guide/#installing-from-wheels

For example if you save in C:/ the you can install via

pip install c:/MySQL_python-1.2.5-cp27-none-win_amd64.whl

Follow-up: if you have a 64bit version of Python installed, then you want to install the 64-bit AMD version of MySQLdb from the link above [i.e. even if you have a Intel processor]. If you instead try and install the 32-bit version, I think you get the unsupported wheel error in comments below.

Question 6

well this worked for me:

pip install mysqlclient

this is for python 3.x

Question 7

I tried all the option but was not able to get it working on Redhat platform. I did the following to make it work:-

yum install MySQL-python -y

Once the package was installed was able to import module as follows in the interpreter:-

>>> import MySQLdb
>>>

Question 8

Go to pycharm then go to default setting –> pip (double click) — pymsqldb..– > install –after installing use in a program like this

import pymysql as MySQLdb

# Open database connection
db = MySQLdb.connect("localhost","root","root","test" )

# prepare a cursor object using cursor() method
cursor = db.cursor()

# execute SQL query using execute() method.
cursor.execute("show tables")

# Fetch a single row using fetchone() method.
data = cursor.fetchall()
print (data)

# disconnect from server
db.close()

Question 9

If you are use Raspberry Pi [Raspbian OS]

There are need to be install pip command at first

apt-get install python-pip

So that just install Sequently

apt-get install python-dev libmysqlclient-dev

apt-get install python-pip

pip install MySQL-python

Question 10

You can go to this website to download the package.

Question 11

If you are unable to install mysqlclient you can also install pymysql:

pip install pymysql

This works same as MySqldb. After that use pymysql all over instead of MySQLdb

Question 12

I had the same problem too.Follow these steps if you are on Windows. Go to: 1.My Computer 2.System Properties 3.Advance System Settings 4. Under the “Advanced” tab click the button that says “Environment Variables” 5. Then under System Variables you have to add / change the following variables: PYTHONPATH and Path. Here is a paste of what my variables look like: python path:

C:\Python27;C:\Python27\Lib\site-packages;C:\Python27\Lib;C:\Python27\DLLs;C:\Python27\Lib\lib-tk;C:\Python27\Scripts

path:

C:\Program Files\MySQL\MySQL Utilities 1.3.5\;C:\Python27;C:\Python27\Lib\site-packages;C:\Python27\Lib;C:\Python27\DLLs;C:\Python27\Lib\lib-tk;C:\Python27\Scripts

See this link for reference

Question 13

The above answer is great, but there may be some problems when we using pip to install MySQL-python in Windows

for example,It needs some files that are associated with Visual Stdio .One solution is installing VS2008 or 2010……Obviously,it cost too much.

Another way is the answer of @bob90937 . I am here to do something to add.

with http://www.lfd.uci.edu/~gohlke/pythonlibs, u can download many Windows binaries of many scientific open-source extension packages for the official CPython distribution of the Python programming language.

Back to topic,we can choose the MySQL-python(py2) or Mysqlclient(py3) and use pip install to install. it gives us Great convenience!

Question 14

For Python3 I needed to do this:

python3 -m pip install MySQL

Question 15

pip install mysql-connector-python as noted in the documentation:

https://dev.mysql.com/doc/connector-python/en/connector-python-installation-binary.html

Question 16

on RHEL 7:

sudo yum install yum-utils mariadb-devel python-pip python-devel gcc

sudo /bin/pip2 install MySQL-python

Question 17

If you have Windows installed on your system then type the following command on cmd :

pip install mysql-connector

if the above command does not work try using:

pip install mysql-connector-python

Now,if the above commands do not get the work done, try using:

pip install mysql-connector-python-rf

That’s it you are good to go now.

Question 18

Many of the given answers here are quite confusing so I will try to put it simply. It helped me to install this

pip install pymysql

and then use the following command in the python file

import pymysql as MySQLdb

This way you can use MySQLdb without any problems.

Question 19

If pip3 isn’t working, you can try:

sudo apt install python3-mysqldb

Question 20

My environment are:

Windows 10 Pro,
Python 3.7 (python-3.7.1-amd64.exe),
MySQL 8.0 (mysql-installer-web-community-8.0.13.0.msi)

pip install mysqlclient-1.3.13-cp37-cp37m-win_amd64.whl

works for me.

import MySQLdb, sys


# --------------------------------------------------
# Connect to MySQL
# --------------------------------------------------
try:
    db = MySQLdb.connect(host="localhost", user="user", passwd="pass", db="database", charset='cp1251')
except MySQLdb.Error as e:
    print ("Error %d: %s" % (e.args[0], e.args[1]))
    sys.exit()

# Creating cursor 
cursor = db.cursor()

Question 21

actually, follow @Nick T’s answer doesn’t work for me, i try apt-get install python-mysqldb work for me
