Question

我的Heroku应用程序正在崩溃，我相信它甚至可以进入Procfile。我遇到了与此相同的问题：

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

唯一的区别是我的package.json文件包含Express

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"
   }
 }

我已在本地尝试过foreman实用程序，一切正常。

我的主要weather.js文件包含：

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

非常感谢任何帮助。

Answer 1

我看到一些你可以改进的东西，正如在他的评论中所说的那样，你应该使用heroku变量来监听端口并拥有IP。

您还应该在package.json中包含：

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

因此系统知道该做什么以及您的快速服务器在哪里

您是否尝试在没有node_modules文件夹的情况下进行部署？一旦推送heroku将安装这些软件包，我的意思是至少仅用于调试目的
