Heroku Node.js应用程序崩溃| module.js：340错误

Question

我的Heroku应用程序崩溃了，我相信在它到达Procfile之前。我在这里遇到了同样的问题：

Cannot execute Node.js app on Heroku successfully (crashes each time)

唯一的区别是，我的package.json文件有快递包括

package.json 
    { 
    "name": "weathersocket", 
    "version": "0.0.1", 
    "description": "text based weather", 
    "main": "weather.js", 
    "scripts": { 
     "test": "echo \"Error: no test specified\" && exit 1" 
     }, 
     "repository": { 
     "type": "git", 
     "url": "https://github.com/agreen757/weathersocket.github.io" 
     }, 
    "keywords": [ 
    "demo", 
    "heroku", 
    "weather" 
    ], 
    "author": "Adrian Green", 
    "license": "MIT", 
    "bugs": { 
    "url": "https://github.com/agreen757/weathersocket.github.io/issues" 
    }, 
    "homepage": "https://github.com/agreen757/weathersocket.github.io", 
    "dependencies": { 
    "body-parser": "^1.6.6", 
    "consolidate": "^0.10.0", 
    "cookie-parser": "^1.3.2", 
    "express": "^4.8.6", 
    "mongodb": "^1.4.9", 
    "socket.io": "^1.0.6", 
    "swig": "^1.4.2" 
    } 
} 

我试图在当地工头工具和一切工作正常。

我的主要weather.js文件包含：

server.listen(4000); 
console.log("Express server started on 4000"); 

任何帮助将不胜感激。

更新：Heroku的日志

Answer 1

我看到了一些东西，你可以改善，因为在他的评论fakemeta状态，你应该使用Heroku的变量来监听端口，并有IP。

你也应该在你的package.json：

"scripts": { 
    "start": "node server.js" 
    }, 
    "main": "server.js" 

所以系统知道做什么，哪里是你Express服务器

你不能尝试部署没有node_modules文件夹？，一旦你推的Heroku将安装这些程序包，我的意思是，至少只是为了调试的目的
