mysql - 无法使用 MySQL 后端运行 Django

Question

我正在尝试使用 MySQL 后端设置 Django，之前我只使用过 sqlite，但我遇到了一个相当奇怪的错误。 错误是:没有名为 mysql.base 的模块

我正在运行带有 Nginx 和 uwsgi 的 Ubuntu，并且安装了 python-mysqldb。在此之后，我开始收到 502，所以我希望这是相关的，因为我没有更改任何配置文件。

这是 manage.py inspectdb 之后的堆栈跟踪；

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

数据库设置；

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

如果我更改为 sqlite3，那么 dj 不会有任何问题；

# This is an auto-generated Django model module.
# You'll have to do the following manually to clean this up:
#     * Rearrange models' order
#     * Make sure each model has one field with primary_key=True
# Feel free to rename the models, but don't rename db_table values or field names.
#
# Also note: You'll have to insert the output of 'django-admin.py sqlcustom [appname]'
# into your database.

from django.db import models

检查您的设置，确保 ENGINE 是正确的 django.db.backends.mysql。

然后确保你已经安装了python-mysqldb...

sudo apt-get install python-mysqldb

但是，在您的错误堆栈中它指出“不是可用的数据库后端”，这似乎是您的 Django 安装出了问题，对吗？
