我是新手。我正在遵循https://www.sitepoint.com/building-facebook-chat-bot-node-heroku/的教程来制作示例 facebook messenger bot。

就在我第一次在heroku中部署它时，我遇到了错误

这是我的 package.json

{
  "name": "spbot",
  "version": "1.0.0",
  "description": "Testbot",
  "main": "app.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "node app.js"
  },
  "author": "Munkh",
  "license": "ISC",
  "dependencies": {
    "body-parser": "^1.17.1",
    "express": "^4.15.2",
    "mongoose": "^4.9.1",
    "request": "^2.81.0"
  }
}

这里是 app.js

    var express = require("express");
var request = require("request");
var bodyParser = require("body-parser");

var app = express();
app.use(bodyParser.urlencoded({extended: false}));
app.use(bodyParser.json());
app.listen((process.env.PORT || 5000));

// Server index page
app.get("/", function (req, res) {
  res.send("Deployed!");
});

// Facebook Webhook
// Used for verification
app.get("/webhook", function (req, res) {
  if (req.query["hub.verify_token"] === "this_is_my_token") {
    console.log("Verified webhook");
    res.status(200).send(req.query["hub.challenge"]);
  } else {
    console.error("Verification failed. The tokens do not match.");
    res.sendStatus(403);
  }
});

我有这样的错误

因为错误没有说明出了什么问题，只是不断崩溃，我找不到解决方案。如果这是一个简单的问题，我很抱歉。

您必须指定您在 package.json 中使用的 node.js 和 npm 版本，如下所述。

指定您在开发中使用的版本。

{
  "name": "spbot",
  "version": "1.0.0",
  "description": "Testbot",
  "main": "app.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "node app.js"
  },
  "author": "Munkh",
  "license": "ISC",
  "dependencies": {
    "body-parser": "^1.17.1",
    "express": "^4.15.2",
    "mongoose": "^4.9.1",
    "request": "^2.81.0"
  },
  "engines": {
    "node": "7.0.0",
    "npm": "3.10.8"
