启动不和谐机器人时出现问题（它不想工作）

Question

第一次做真正的javascript项目（之前用过一点点js，仅此而已）。我正在尝试制作一个不和谐的机器人。我将它托管在 heroku 上，但在部署我的项目时出现无法解决的错误。这是日志中的内容：

我的电脑上已经有这个错误了，我刚刚升级了node版本就没有了。但是，我不知道如何处理 heroku。此外，当我在我的计算机上修复错误时，它似乎可以正常工作，但是当我输入“!ping”时，机器人没有回答我，不和谐。

所以我有两个问题：

'UnhandledPromiseRejectionWarning'，在 heroku
我的机器人不工作

有人可以帮助我。

以下是版本：

node : v16.7.0
discord.js : v13.1.0

这是我的代码：

index.js

const { Client, Intents } = require('discord.js');
const client = new Client({
    intents: [
        Intents.FLAGS.GUILDS
    ]
});

const prefixCmd = '!';

client.on("ready", () => {
    console.log("I'm ready !");
});

client.on("message", msg => {

    if(!msg.content.startsWith(prefixCmd) || msg.author.bot) return

    const args = msg.content.slice(prefixCmd.length).trim().split(/ +/);
    const command = args.shift().toLowerCase();

    if (command === "ping") {
        msg.reply("pong");
    }
});

client.login("MY TOKEN");

package.json

{
  "name": "ha",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "dependencies": {
    "discord.js": "^13.1.0",
    "node": "^16.6.0"
  },
  "devDependencies": {},
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "repository": {
    "type": "git",
    "url": "git+https://github.com/......"
  },
  "author": "",
  "license": "ISC"
}

Answer 1

要解决此问题，您必须添加：

"engines": {
    "node": "16.7.0" 
}

到package.json

Answer 2

要使 heroku 正常工作，您需要从 package.json 中的依赖项中删除节点。

并在 package.json 中添加：

"engines": {
    "node": "16.7.0" 
}

对于运行的机器人，您不能写：

const { Client, Intents } = require('discord.js');
const client = new Client({
    intents: [
        Intents.FLAGS.GUILDS
    ]
});

但是你必须写：

const { Client, Intents } = require('discord.js');
const client = new Client({
    intents: [
        "GUILDS",
        "GUILD_MESSAGES",
        "DIRECT_MESSAGES"
    ],
    partials: [
    "CHANNEL"
    ]
});
