heroku + node + express + hogan 无法启动，日志中没有信息

Question

我的 Heroku 应用程序无法启动，当我在浏览器中加载页面时，它只给我通用的

Application Error

An error occurred in the application and your page could not be served. Please try again in a few moments.

If you are the application owner, check your logs for details.

而且我检查我的 heroku 日志几乎只说“State changed from starting to crashed”。

当我在浏览器中加载页面并看到上面的错误时，日志显示

2015-04-01T23:11:20.387769+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=surrealist-debate.herokuapp.com request_id=2c304a35-950a-422d-9174-4d558cbd4d40 fwd="172.3.184.57" dyno= connect= service= status=503 bytes=

这是我的package.json:

{
  "name": "surrealist-debate",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "node ./bin/www"
  },
  "dependencies": {
    "body-parser": "~1.12.0",
    "cookie-parser": "~1.3.4",
    "debug": "~2.1.1",
    "express": "~4.12.2",
    "hjs": "~0.0.6",
    "morgan": "~1.5.1",
    "serve-favicon": "~2.2.0"
  }
}

当运行通过 foreman foreman start web 在本地 Procfile

web: node routes/index.js

foreman 给我这个错误：

16:31:34 web.1  | started with pid 12073
16:31:34 web.1  | exited with code 0
16:31:34 system | sending SIGTERM to all processes

我可以但是运行它直接在本地使用DEBUG： DEBUG=surrealist-debate:* ./bin/www

它在本地工作： surrealist-debate:server Listening on port 3000 +0ms

这是怎么回事？！我怎样才能在 Heroku 和工头上将其发送到运行而不是在没有任何信息的情况下立即退出并崩溃？

Answer 1

好的，看来问题出在 Procfile 上！当它应该指向 bin/www 时它试图运行 routes/index.js （它做它的事情然后执行 index.js，这反过来服务于正确的 views/index .hjs)

对于看到类似错误但日志中没有信息的所有其他人，请检查您的 Procfile ;)
