node.js和Heroku错误：Web进程在启动后60秒内绑定到$端口失败

Question

我一直在尝试用heroku制作一个bot，当我部署它时，我得到了这个错误:
Web进程未能在启动60秒内绑定到$port。

这是我的index.js：

const discord = require('discord.js');
const bot = new discord.Client();

const token = 'Nzc0MjQxOTAyMzE2MjI0NTIy.X6U69g.sjmAievx3II561tvYfOVy72an1k';

bot.on('ready', () =>{
    console.log('This bot is online');
})

bot.on('message', message=>{
    if(message.content === "im lost"){
        message.channel.send('You should try finding your way through the welcome channel!')
    }
        if(message.content === "i need help"){
        message.channel.send('Check out the bot-help channel!')
    }
})

bot.login(token);

package.json：

{
  "name": "compass",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
   "start": "node index.js"
},

}

Answer 1

你在Heroku上设置了一个web dyno，而不是一个worker dyno。不和机器人是工人。

在Heroku应用程序的resources选项卡上，关闭web dyno，并打开一个worker dyno。
