我完全迷失了，无法找到问题的解决方案。我启动了 virtualenv 并使用 python 版本 2.7 在其中安装了最新版本的 django。然后我按照 django 教程进行操作，但我没有在开发服务器上工作，而是使用了 apache2 localhost，一切都工作正常。然后为了检查 mysql 支持，我更改了设置文件并安装了 mysqlclient 并使用了 python manage.py makemigrations ，然后使用了 python manage.py migrate一切顺利。最后我重新启动apache，出现500 Internal Server Error。我现在提供 apache 错误日志和我的设置文件。

这是有关数据库配置的settings.py内容。
DATABASES = {

'ENGINE': 'django.db.backends.mysql',
'NAME': 'roadrunner',
'USER': 'root',
'PASSWORD': 'kapilgarg',

}
}
从apache错误日志的最后一行，它指向_mysql.so: undefined symbol ，似乎存在一些链接问题或版本不匹配问题。有人可以帮我吗？我们将不胜感激。
最佳答案
在虚拟环境中安装模块
pip install MySQL-python
关于python - Django 中的 MySQLdb 错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35206855/
