为什么数据库迁移迁移不成功里面settings.py都改了DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql', # 指定使用的数据库引擎为 MySQL
'NAME': 'myblog', # 数据库的名称
'USER': 'root', # 连接数据库的用户名
'PASSWORD': '111111', # 连接数据库的密码，注释中提示应该替换成自己的密码
'HOST': '127.0.0.1', # 数据库服务器的主机地址，通常是本地主机
'PORT': '3306', # 数据库服务器的端口号，MySQL 默认端口是 3306
}
}。这是报错的

喔你居然回复了谢谢但是没关系了现在，感觉python在软件开发方面上没有太大的空间。很多java而且特别卷。
