我正在尝试制作一个使用mysql作为数据库引擎的Django应用程序。我遵循了一个教程，其中说我必须使用pip下载pymysql软件包。我使用了下一个命令pip install pymysql。 Unitl在这里所有工作。下一步是在django项目中进行迁移，但是当我尝试进行迁移时，它将引发下一个错误：

它说我的mysqlclient是较旧的版本，我需要对其进行升级，但是当我尝试使用pip install mysqlclient安装mysqlclient时，它会抛出下一个错误：

我尝试使用pip install --update mysqlclient，但也不起作用。我该如何解决？我正在使用python 3.7.3和MacOS Mojave。
