问题描述
我的团队正在使用 MysqL 开发 Django 项目。
我已经克隆了一个项目存储库并安装了所有依赖项，但是，当我使用 python3 manage.py runserver 运行该项目时，出现以下错误：
Exception in thread django-main-thread:

正在开发新的 Mac M1 操作系统 11.0.1 版
尝试使用 sudo ln -s /usr/local/MysqL/lib/libMysqLclient.21.dylib /usr/local/lib/libMysqLclient.21.dylib 解决问题，但没有奏效。
MysqL 已安装，检查 libMysqLclient.21.dylib 和 _MysqL.cpython-38-darwin.so 是否存在于相应目录中。
还尝试使用 install-name-tool 更改 @rpath ，但也没有运气。
