python - 无法启动python manager.py runserver

我正在使用Python V3.6和Django V2.1创建一个示例应用程序，以前我遇到过与MySQL客户端有关的问题，因此我已通过使用“ pip install "mysqlclient==1.3.12”修复了该问题，可帮助成功安装mysqlclient，但稍后当我尝试运行我的应用程序时，出现以下错误。

Setting.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': '****',
        'USER': '****',
        'PASSWORD': '****',
        'HOST': 'localhost',   # Or an IP Address that your DB is hosted on
        'PORT': '3306',
    }
}

如果我尝试使用默认数据库（sqlite3），则可以正常工作，但是当我尝试将其更改为Mysql时，出现此错误。

最佳答案

确保您提供了有效的凭据并安装了最新的mysqlclient。要安装mysqlclient，请使用命令pip install -I mysqlclient。
