node.js - 缺少脚本 : start & App crashed when deploying app to Heroku

Question

我是编码新手，但目前正在学习，因为我想在我的 Facebook 页面上创建一个聊天机器人。下面是我在每个 .js 中的脚本以及我之后遇到的错误。输入 heroku open 后，网页显示“应用程序错误应用程序发生错误，无法提供您的页面。如果您是应用程序所有者，请查看您的日志以了解详细信息。”

希望有人能帮帮我，非常感谢!

index.js

var express = require('express')
var bodyParser = require('body-parser')
var request = require('request')
var app = express()

app.set('port', (process.env.PORT || 5000))

// Process application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({extended: false}))

// Process application/json
app.use(bodyParser.json())

// Index route
app.get('/', function (req, res) {
    res.send('Hello world, I am a chat bot')
})

// for Facebook verification
app.get('/webhook/', function (req, res) {
    if (req.query['hub.verify_token'] === 'my_voice_is_my_password_verify_me') {
        res.send(req.query['hub.challenge'])
    }
    res.send('Error, wrong token')
})

// Spin up the server
app.listen(app.get('port'), function() {
    console.log('running on port', app.get('port'))
})

package.json

{
    "name": "node",
    "version": "1.0.0",
    "description": "facebook chatbot",
    "main": "index.js",
    "scripts": {

    }
}

我已经尝试并阅读了很多其他人在 github 上提出的问题，但我仍然无法解决问题。我从以下网站学习了设置nodejs和heroku服务器的方法:https://chatbotsmagazine.com/have-15-minutes-create-your-own-facebook-messenger-bot-481a7db54892

我真诚地希望有人能帮助我解决问题，非常感谢!!

Procfile 文件名应该只是Procfile，我看到你的文件名好像是Procfile.json，可能是吧。

但是当你的 package.json 有启动脚本时，只要确保你有 git 添加你所有的文件并在推送到 Heroku 之前提交它们
