Question

我从github克隆了一个Django项目。但是当我运行python manage.py runserver时，它显示了以下错误。如何解决它们？

    python manage.py runserver
Traceback (most recent call last):

在您的.env或.ini文件中，您需要定义DATABASE_URL：

 DATABASE_URL=mysql://myuser:mypassword@myhost/mydatabase

在settings.py中更改为以下内容：

from dj_database_url import parse as db_url

DATABASES = {
    'default': config('DATABASE_URL', cast=db_url),
}
