请提供 ENGINE 值 Django 数据库配置

伙计们，我很困惑，我已经安装了 Django，并正常运行服务器，但是当尝试配置数据库并运行 db 同步命令时，它崩溃，返回我的 ENGINE 参数不正常，但设置文件正常。按照设置文件操作：

    DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': 'mysite',                      # Or path to database file if using sqlite3.
        'USER': 'root',                      # Not used with sqlite3.
        'PASSWORD': '',                  # Not used with sqlite3.
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
    }
}

和错误：

提前致谢！

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'mysite',
        'USER': 'mysite',
        'PASSWORD': '',
        'HOST': 'localhost',
        'PORT': '3306',
     }
}

使用上述设置请检查 mysql 用户的授予权限并指定主机和端口。
