我已经尝试了很多方法来解决这个问题,但我没有解决。我在 google 和 stackoverflow 上搜索了很多,没有适合我的选项。请帮我。提前致谢。我正在使用 django 1.10,python 3.4。我试过了:

  1. pip 安装 mysqldb。
  2. pip 安装 mysql。
  3. pip 安装 mysql-python。
  4. pip 安装 MySQL-python。
  5. easy_install mysql-python。
  6. easy_install MySQL-python。

还剩下什么吗?

最佳答案

MySQLdb 是 MySQL 数据库的接口(interface)。正如其他帖子所提到的,MySQLdb 不支持 Python 3.x。我使用 PyMySQL 作为替代品。您需要先安装它:

pip install PyMySQL

下一步是将所有代码中的“MySQLdb”替换为“pymysql”,这很吓人。幸运的是,PyMySQL 可以作为 MySQLdb 动态加载。为了在 Django 中实现它,您需要将以下行添加到项目默认应用程序目录下的 __init__.py 文件中(如果您有一个名为“myproject”的项目,请将行添加到 myproject/myproject/init.py) :

import pymysql
pymysql.install_as_MySQLdb()

这个__init__.py会在你运行Django项目的时候执行,MySQLdb会被替换掉。你的问题就解决了。
