开发Discord每日金币功能时遇TypeError: ms is not a function错误

错误原因 #

你使用了动态import("parse-ms")，它返回的是一个Promise对象，而非直接可用的函数，因此调用ms()时会触发类型错误。同时你的代码采用CommonJS模块规范（用require导入discord.js），应使用对应规范的方式导入parse-ms。

修复方案 #

1. 修正parse-ms的导入方式 #

将动态import替换为CommonJS的require导入：

const ms = require("parse-ms");

2. 优化数据库操作（可选） #

给db.add和db.set加上await，确保数据库操作完成后再执行后续逻辑，避免异步操作引发的潜在问题。

修改后的完整代码 #

const discord = require("discord.js");
const ms = require("parse-ms");

module.exports = {
    name: "daily",
    aliases: ["coins-system"],
    category: "economy",
    description: "Gives You 200 per day",
    usage: " ",
    accessableby: "everyone",
    run: async (client, message, args, db) => {
        let blacklisted = await db.get(`blacklisted_${message.author.id}`);
        if (blacklisted) return message.channel.send('You cannot use this bot since you are blacklisted');
        
        let user = message.author;
        let timeout = 86400000;
        let amount = 150;
        
        let vip = await db.get(`vip_${message.author.id}`);
        if (vip) amount = 350;

        let daily = await db.get(`daily_${user.id}`);

        if (daily !== null && timeout - (Date.now() - daily) > 0) {
            let time = ms(timeout - (Date.now() - daily));

            let timeEmbed = new discord.EmbedBuilder()
                .setDescription(`❌ You've already collected your daily reward\n\nCollect it again in ${time.hours}h ${time.minutes}m ${time.seconds}s `);
            message.channel.send(timeEmbed);
        } else {
            let moneyEmbed = new discord.EmbedBuilder()
                .setDescription(`✅ You've collected your daily reward of ${amount} coins`);
            message.channel.send(moneyEmbed);
            await db.add(`cash_${user.id}`, amount);
            await db.set(`daily_${user.id}`, Date.now());
        }
    }
};
