python - MySQL 上的检查数据库抛出异常

Question

我正在尝试运行inspectdb，但出现连接不存在错误!我在 MySQL 中有一个名为 myapp 的数据库以及其他数据库。

这是我的设置.py

DATABASES = {
'default': {
    'ENGINE':'django.db.backends.mysql',
    'NAME': 'myapp',
    'USER': '*****',
    'PASSWORD': '****',
    'HOST': 'ec2-11-111-111-11.compute-1.amazonaws.com',
    'PORT': '8000',
    }
}

项目结构:

mysite/
   manage.py
   mysite/
       settings.py

这就是发生的事情:

root@ip-10-202-209-99:~/Desktop/mysite# python manage.py inspectdb --database myapp Traceback (most recent call last):

django.db.utils.ConnectionDoesNotExist: The connection myapp doesn't exist

Answer 1

 The connection myapp doesn't exist

这意味着数据库尚未创建。
