这个货币机器人的正确组织是什么 - 代码明智？

Question

我收到一条错误消息，“await 仅在异步函数中有效”，这让我认为我没有为代码添加任何内容，或者我放错了位置。或者也许我需要制作另一个主文件，因为这个文件有点大而且杂乱？但我不知道出了什么问题……感谢您的帮助。

const Discord = require("discord.js");

const Sequelize = require('sequelize');

这当然是强制性的，正确的^^^

const fs = require("fs");
const client = new Discord.Client();
const { Users, CurrencyShop } = require('./dbObjects');
const { Op } = require('sequelize');
const currency = new Discord.Collection();
const prefix = "&";

这部分很乱，是它可能无法正常工作的原因吗？^^^ 下面是我可能搞砸的信息？

client.once('ready', async () => {
    // [beta]
    console.log(`Logged in as ${client.user.tag}!`);
});

client.on('message', async message => {
    if (message.author.bot) return;
    currency.add(message.author.id, 1);

if (!message.content.startsWith(PREFIX)) return;
const input = message.content.slice(PREFIX.length).trim();
if (!input.length) return;
const [, command, commandArgs] = input.match(/(\w+)\s*([\s\S]*)/);

下面写的一些命令可能最好忽略。

if (command === 'balance') {
    // [gamma]
} else if (command === 'inventory') {
    // [delta]
} else if (command === 'transfer') {
    // [epsilon]
} else if (command === 'buy') {
    // [zeta]
} else if (command === 'shop') {
    // [theta]
} else if (command === 'leaderboard') {
    // [lambda]
}

});

您需要将带有等待参数的每一行放入异步函数中。 例如：

async function yourFunction() {
    const storedBalances = await Users.findAll();
    storedBalances.forEach(b => currency.set(b.user_id, b));
}

然后对其中包含 await 的所有其他行执行此操作。
