启动不和谐机器人时出现问题(它不想工作)

Question

这是我第一次做一个真正的javascript项目(我以前使用过一点js，但仅此而已)。我在试着制造一个不和谐的机器人。我把它托管在heroku上，在部署我的项目时，我得到了一个我无法解决的错误。以下是日志中的内容:

我已经在我的电脑上有这个错误，我刚刚改进了node的版本，我没有更多的错误。然而，我不知道该怎么对付英雄。此外，当我在电脑上修复错误时，它似乎可以工作，但是当我输入'!Ping ' bot没有回答我，on discord。

所以我有两个问题:

1. UnhandledPromiseRejectionWarning'，在heroku上
2. 我的机器人不工作

有人能帮帮我吗?

版本如下:

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

下面是我的代码:

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

要解决这个问题，您必须添加:

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

到package.json

Answer 2

要使heroku工作，您需要从package.json中的依赖项中删除node。

并在包中添加。json:

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

要让bot运行，你不能写:

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"
]
});
