【问题描述】：

我收到此错误：

botcommandsmoney.get('auction').run(bot, message, args, err, auctionhouse)

我的所有其他命令都可以使用（狙击和帮助），但 *auctionhouse 不行。

我的 *auctionhouse 命令代码：

module.exports = 
    name: 'help',
    description: "Help command!",
    execute(bot, message, args, err, auctionhouse)
    const Discord = require('discord.js')
    const embed = new Discord.MessageEmbed()
    .setTitle('Auction House')
    .setDescription('To bid on an item, run `*bid <id> <amount>`.')
    .addField(`$auctionhouse.item1.name - $$auctionhouse.item1.currentprice - ID: \`$auctionhouse.item1.id\``)
    .addField(`$auctionhouse.item2.name - $$auctionhouse.item2.currentprice - ID: \`$auctionhouse.item2.id\``)
    .addField(`$auctionhouse.item3.name - $$auctionhouse.item3.currentprice - ID: \`$auctionhouse.item3.id\``)
    .setColor("RANDOM")
    message.channel.send(embed)

【问题讨论】：

你的auction.js里面有什么？我敢打赌name 没有auction，可能是您从另一个文件中复制了它而忘记更新名称。所以，botcommandsmoney.set 会被调用，而不是auction，而botcommandsmoney.get('auction') 会返回undefined，因此butcommandsmoney.get('auction').run() 会抛出错误cannot read property 'run' of undefined。

@CherryDT 只是仔细检查了一遍，不，肯定是auction.js。

不，我说的是：检查 auction.js 的 inside 设置的 name 属性。您的代码通过名称属性而不是文件名分配机器人功能。

哦，谢谢！这是“帮助”！

不客气。 （这个问题现在可能要结束了。）

【参考方案1】：

代码botcommandsmoney.get('auction').run(...) 抛出错误Cannot read property 'run' of undefined，表示botcommandsmoney.get('auction') 返回undefined。因此，我假设没有定义 auction bot 命令。

我们可以看到您正在加载./cmds/money 中的所有文件，并使用botcommandsmoney.set(command.name, command) 行将它们的导出设置为botcommandsmoney 中的命令。看来，定义如何在botcommandsmoney 中调用命令的信息来自command.name，即文件中的属性name。

查看您的auction.js 文件，我们可以看到属性name 的值是help 而不是auction！所以，botcommandsmoney.get('help') 而不是botcommandsmoney.get('auction') 会返回你的命令...我认为这是一个复制粘贴错误，你可能从另一个命令复制了文件并忘记更新其中的name，即使你重命名文件本身。

因此，解决方法是将auction.js 中的name: 'help' 更改为name: 'auction'。
