【问题描述】：
我正在尝试从从数据库返回的 ID 中查找用户名，但是我遇到了问题。我遇到的问题是用户在突击队命令中，而且我似乎无法运行 discord.js 函数，例如 .fetchUser。我试过了，不过，你们应该都比我知道该怎么做！
const commando = require ('discord.js-commando');
const { RichEmbed } = require('discord.js');
const sqlite3 = require ('sqlite3');
class claim extends commando.Command
{
constructor(client )
{
super(client,{
name: 'marry',
group: 'simple',
memberName: 'marry',
description: 'Marries the user tagged for a specified cost.'
});
}
async run(message, args)
{
var updatedbalance;
const string = message.content.slice(1).trim().split(/ +/g);
const user = message.mentions.users.first().id;
const username = message.mentions.users.first();
const payment = string[2]
let db = new sqlite3.Database('./duncanbot.db')
function getBalance(id, callback)
{
var query = "SELECT balance FROM main WHERE userid = " + id;
db.all(query, function (err, rows) {
if(err){
console.log(err);
}
else
{
try{
callback(rows[0].balance);
}
catch (err)
{
console.log(err)
}
}
});
}
function getAvailPrice(mention, callback)
{
var query = "SELECT price FROM partners WHERE partner = " + mention;
db.all(query, function (err, rows) {
if(err){
console.log(err);
}
else
{
try
{
callback(rows[0].partner, rows[0].price);
}
catch (err)
{
callback(mention, '0')
console.log(err)
}
}
});
}
function findBal(balance)
{
updatedbalance = balance - payment
if (balance >= payment)
{
getAvailPrice(user, findAval);
}
else
{
const marryembed = new RichEmbed()
.setTitle('You do not have the required funds')
.setAuthor(message.author.username, message.author.displayAvatarURL)
.setColor(0x8AC784);
message.channel.send(marryembed);
}
}
function updateDB()
{
db.run(`INSERT INTO partners (userid, partner, price) VALUES(${message.author.id}, ${user}, ${payment})`)
}
function findAval(partner, price) {
if (payment > price)
{
try{
db.run(`UPDATE main SET balance = ${updatedbalance} WHERE userid = ${message.author.id}` );
if (price == 0)
{
db.run(`INSERT INTO partners (userid, partner, price) VALUES(${message.author.id}, ${user}, ${payment})`);
}
else if (price > 0)
{
db.run(`DELETE FROM partners WHERE partner = (${user})`)
setTimeout(updateDB,500)
}
else
{
console.log(err)
}
const marryembed = new RichEmbed()
.setTitle('You have married ' + username.username)
.setAuthor(message.author.username, message.author.displayAvatarURL)
.setColor(0x8AC784);
message.channel.send(marryembed);
}
catch(err)
{
console.log(err)
}
}
else
{
const marryembed = new RichEmbed()
.setTitle('You must pay more than the current amount, which is ' + price)
.setAuthor(message.author.username, message.author.displayAvatarURL)
.setColor(0x8AC784);
message.channel.send(marryembed);
}
}
getBalance(message.author.id, findBal);
};
}
module.exports = claim;

从您的代码来看，问题出在哪里还不是很清楚，从技术上讲，您可以在声明它的地方使用任何 Discord 方法。请指定任务并提供更多您有困难的代码。据我了解，这里涉及到几个模块。

@Cipher 我会把所有的代码都加进去，就这么简单
