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，但无法运行服务器。
请有人帮助我，我是Python / Django的新手，我无法提前更多。
cmd显示执行命令时的下一个错误。

很明显，Django无法在指定位置找到您的数据库，原因可能是，

  • 您已使用"sudo"或与当前用户之外的任何其他Linux用户创建了django项目，这就是您当前用户可能无权访问该数据库的原因。 您可以通过键入项目的根目录来检查文件的权限，

    ls -la

  • 您已在settings.py中为数据库文件配置了错误的路径

    • 我相信您正在寻找的解决方案如下：

    1
    sudo python manage.py runserver

    我正在努力解决同样的问题，这终于为我做了诀窍。
