django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?
升级之前，mysqlclient 没有任何问题。尝试运行我的 django 环境时出现此错误。我尝试了在线找到的所有方法，但均无效。我确实安装了 pip 包。
我已尝试完全删除 mysqlserver，重新安装 python-dev 和 PyPi 页面上提到的 mysqlclient 包的所有依赖项。
答案1
运行以下命令应该可以帮助我得到同样的错误并以这种方式修复。
sudo apt-get install python3-dev
pip install mysqlclient
希望有帮助
