Python/Django 运行 开发服务器
Python/Django run development server
我正在尝试使用 Django 1.8.4 和 Python 2.7.10 创建一个项目，但我无法执行命令 python manage.py runserver。我可以创建项目和应用程序，但不能 运行 服务器。
请有人帮助我，我是 Python/Django 的新手，我不能再进步了。
cmd 在执行命令时显示下一个错误。

我相信您正在寻找的解决方案如下：
sudo python manage.py runserver
我一直在为同样的问题而苦苦挣扎，这终于为我解决了问题。
超级用户做来救援！

很明显 Django 无法在指定位置找到您的数据库，原因可能是，
您使用 "sudo" 或与当前用户以外的任何其他 linux 用户创建了 django 项目，这就是为什么您的当前用户可能没有访问该数据库的权限.您可以通过输入项目的根目录来检查文件的权限，
ls -la
您在 settings.py
