我一直在尝试阅读与此问题相关的所有内容（并在此过程中学到了很多）。我找到的最接近的链接是这里和这里。我的问题几乎完全相同，只是我专门在emperor模式下运行uwsgi。当我在不运行emperor模式的情况下运行uswsgi服务时，我的django网站运行得非常好。无论我如何更改配置，我总是会在我的/tmp/uwsgi.log文件中收到错误消息："--- no python application found, check your startup logs for errors ---"。我在下面列出了我的配置和错误日志：
操作系统版本：Linux raspberrypi 3.6.11+ #538 armv6l GNU/Linux Django版本：1.6.5 uwsgi版本：2.0.5.1
虚拟环境：/var/www/testbed/env 项目位置：/var/www/testbed/project/auth 项目树：
正在执行的命令如下所示：
此时此刻，我已经是不折不扣的无助了。我浏览了大量的文献，但却不明白为何会一直出现“内部服务器错误”的提示。可能是我忽略了某个细节，所以我最终放下面子在这里寻求帮助。既然我已经走到了这一步，我真心觉得问题可能只是一个微不足道的小错误。如有任何帮助，将不胜感激。
