MySQL-Python & Django 1.5.0: no module named mysql

问题:

I am trying to create database table with Django by python manage.py syncdb and get an error Error was: No module named mysql.base. I know there are many questions like this on the web but none one of them helped me.

Python version: 2.7.3 (default, Aug 1 2012, 05:16:07) \n[GCC 4.6.3].

Django version: (1, 5, 0, 'final', 0).

MySQL-Python version: MySQL_python-1.2.4b4-py2.7-linux-i686.

System information: Linux Marlon 3.5.0-26-generic #42~precise1-Ubuntu SMP Mon Mar 11 22:19:42 UTC 2013 i686 athlon i386 GNU/Linux

MySQL version: mysql Ver 14.14 Distrib 5.5.29, for debian-linux-gnu (i686) using readline 6.2

My setting.py file:

...
DATABASES = {
  'default': {
    'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
    'NAME': 'a',                      # Or path to database file if using sqlite3.
    # The following settings are not used with sqlite3:
    'USER': 'a',
    'PASSWORD': 'a',
    'HOST': 'a',                      # Empty for localhost through domain sockets or '127.0.0.1' for localhost through TCP.
    'PORT': '',                      # Set to empty string for default.
  }
}
...

Error code:

Try using 'django.db.backends.XXX', where XXX is one of:
u'oracle', u'postgresql_psycopg2', u'sqlite3'
Error was: No module named mysql.base`

And import MySQLdb works fine in the interactive shell.

What am I doing wrong?

回答1:

Seems like something is wrong with your Django installation: it's listing the packages available under django.db.backends, and doesn't mention mysql for some reason. I would try deleting Django completely and re-installing it.

(I'm also confused by the fact that you have Django 1.5 under dist-packages. That's for packages provided by the distribution, and Django 1.5 is too new to have made it into any distributions yet. Maybe you have two conflicting installations?)
