【问题描述】：
我在 heroku 上部署了一个应用程序，它可以工作，但是当我转到链接时，我收到一个应用程序错误。当我在控制台中访问 heroku 日志时，我看到的是这样的：

如果有人能提供帮助，那就太好了。
【问题讨论】：
-
您的
./bin/www文件是什么样的？那里出了点问题。 -
可能是
generator-express从本指南sahatyalkabov.com/…生成的那个 -
我从那个损坏的指南中注意到了这一步：“删除视图、路由和 bin 目录，因为您将不再需要它们”——您没有碰巧遵循该建议，对吗？因为如果您的 package.json 正在寻找 bin/www 并且它不存在，那么这就是您的问题。
