Python MySQLdb not importing

Question

I have installed mysql server using

$ sudo apt-get install mysql-server

then I installed python-mysqldb using

$ sudo apt-get install python-mysqldb

but when I import MySQLdb in python it shows the following error

>>> import MySQLdb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named MySQLdb

I reinstalled both mysql server and python-mysqldb but it shows the same error. What am I getting wrong?

Answer 1

您需要使用 pip pip install mysql-python安装模块

Answer 2

Python module names are case sensitive, even on case-insensitive file systems. Therefore "MySQLdb" and "mysqldb" are two different modules/packages. Use import MySQLdb instead.

Answer 3

试试这些命令

sudo apt-get install python-dev libmysqlclient-dev

sudo pip install MySQL-python

Answer 4

The package name is "MySQLdb". Case counts.

Answer 5

Your code snippet is fine. So the problem lies with getting libraries to match up. Here are some tools to help track it down... but do post back to let us know how this worked out for you:

$ python --version
Python 2.6.6
$ easy_install yolk
$ yolk --list
DecoratorTools  - 1.7          - active
MySQL-python    - 1.2.2        - active
...

$ pydoc -p 8080
pydoc server ready at http://localhost:8080/

$ python
>>> import MySQLdb
>>> help('modules')
Please wait a moment while I gather a list of all available modules...    
ArgImagePlugin      _bytesio            exceptions          pyexpat
BaseHTTPServer      MspImagePlugin      cProfile            multifile
MySQLdb  ....


$ dpkg -L python-mysqldb
/usr/lib/pyshared/python2.7/_mysql.so
/usr/lib/pyshared/python2.6/_mysql.so

Note the Ubuntu package installs mysql to several python versions.

Answer 6

"mysql-python" currently does not support python3. There are currently a few options for using Python 3 with mysql. I installed mysqlclient and can import MySQLdb successfully.

$ pip install mysqlclient

$ python
Python 3.6.9 (default, Nov  7 2019, 10:44:02) 
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import MySQLdb
>>>

Answer 7

Why not try installing from the synaptic package manager instead. You could install python-mysqldb-dbg also.
