使用我从 repo 克隆的 WOK Thanks Command 代码，并进行了一些编辑，但是ReferenceError: Invalid left-hand side in assignment当我输入命令时，我从不和谐中获得了来自 commando 的代码。

代码：

const Commando = require('discord.js-commando')
const Discord = require('discord.js')
const thanksSchema = require('@schemas/thanks-schema')

module.exports = class ThanksCommand extends Commando.Command {
    constructor(client) {
        super(client, {
            name: 'thanks',
            group: 'thanks',
            memberName: 'thanks',
            description: 'Thanks a staff member for their help',
        })
    }

    async run(message) {
        const target = message.mentions.users.first()
        if (!target) {
            const noPingThanksEmbed = new Discord.MessageEmbed()
            .setTitle('ERROR: Invalid user provided')
            .setDescription('Please tag a valid user')
            .setColor('#ff0000')
            message.channel.send(noPingThanksEmbed)
            return
        }

        const { guild } = message
        const guildId = guild.id
        const targetId = target.id
        const authorId = message.author.id
        const now = new Date()

        if (targetId === authorId) {
            const thankSelfEmbed = new Discord.MessageEmbed()
            .setTitle('ERROR: Invalid user provided')
            .setDescription('You cannot thank yourself')
            .setFooter('LOL YOU THOUGHT')
            .setColor('#ff0000')
            message.channel.send(thankSelfEmbed)
            return
        }

        const authorData = await thanksSchema.findOne({
            userId: authorId,
            guildId,
        })

        if (authorData && authorData.lastGave) {
            const then = new Date(authorData.lastGave)

            const diff = now.getTime() = then.getTime()
            const diffHours = Math.round(diff / (1000 * 60 * 60))
            const hours = 24

            if (diffHours <= hours) {
                const cooldownThankEmbed = new Discord.MessageEmbed()
                .setTitle('ERROR: User on cooldown')
                .setDescription(`You have already thanked someone within the last ${hours} hours`)
                .setColor('#ff0000')
                message.channel.send(cooldownThankEmbed)
                return
            }
        }

        await thanksSchema.findOneAndUpdate({
            userId: authorId,
            guildId,
        }, {
            userId: authorId,
            guildId,
            lastGave: now,
        }, {
            upsert: true,
        })

        const result = await thanksSchema.findOneAndUpdate({
            userId: targetId,
            guildId,
        }, {
            userId: targetId,
            guildId,
            $inc: {
                received: 1,
            }
        }, {
            upsert: true,
            new: true,
        })

        const amount = result.received

        const thanksEmbed = new Discord.MessageEmbed()
        .setTitle('SUCCESS')
        .setDescription(`<@${authorId}> has thanked <@${targetId}!\n\nThey now have ${amount} thanks`)
        .setColor('#1be730')
        message.channel.send(thanksEmbed)
    }
}

这是架构：

const mongoose = require('mongoose')

const reqString = {
    type: String,
    required: true,
}

const thanksSchema = mongoose.Schema({
    userId: reqString,
    guildId: reqString,
    received: {
        type: Number,
        default: 0
    },
    lastGave: Date
})

module.exports = mongoose.model('thanks', thanksSchema)

该代码不会在控制台本身返回任何错误，只是不和谐，并且机器人继续运行，就好像什么都没发生一样，但是该命令不起作用，因为进程已停止。我找不到操作员的任何明显问题，这是我期望从这个错误中得到的......

错误不是来自 Discord.JS 或 Commando，而是来自run()函数中的这一行

const diff = now.getTime() = then.getTime()

你是这个意思吗？

const diff = now.getTime() - then.getTime()

抛出错误时，查找发出错误的文件路径和行
