为什么我在 discord.js 中收到客户端错误

Question

我正在我的 discord.js 机器人中使用此 Discord.js Guide 创建 !stats 命令。由于我使用的是基本命令处理程序，因此这是我的 stats.js 代码：

module.exports = {
    name: 'stats',
    description: 'React to a message',
    execute(message, client) {
        message.channel.send(`Server count: ${client.guilds.cache.size}`);
    },
};

然后我收到这个错误：

TypeError: Cannot read property 'cache' of undefined
    at Object.execute (E:\The Owner\Naffy Dharni\Discord\Bots\Toxado Manager\commands\Utility\stats.js:5:55)
    at Object.execute (E:\The Owner\Naffy Dharni\Discord\Bots\Toxado Manager\events\message.js:69:12)
    at Client.<anonymous> (E:\The Owner\Naffy Dharni\Discord\Bots\Toxado Manager\bot.js:30:61)
    at Client.emit (events.js:315:20)
    at MessageCreateAction.handle (E:\The Owner\Naffy Dharni\Discord\Bots\Toxado Manager\node_modules\discord.js\src\client\actions\MessageCreate.js:31:14)

    at WebSocketManager.handlePacket (E:\The Owner\Naffy Dharni\Discord\Bots\Toxado Manager\node_modules\discord.js\src\client\websocket\WebSocketManager.js:384:31)
    at WebSocketShard.onPacket (E:\The Owner\Naffy Dharni\Discord\Bots\Toxado Manager\node_modules\discord.js\src\client\websocket\WebSocketShard.js:444:22)  
    at WebSocketShard.onMessage (E:\The Owner\Naffy Dharni\Discord\Bots\Toxado Manager\node_modules\discord.js\src\client\websocket\WebSocketShard.js:301:10) 
    at WebSocket.onMessage (E:\The Owner\Naffy Dharni\Discord\Bots\Toxado Manager\node_modules\ws\lib\event-target.js:132:16)

我该怎么做才能解决这个问题？

Answer 1

你discord.js使用的是什么版本？
在 12 版本上添加了缓存。使用 npm i discord.js@12 或仅删除字段 cache.

上的调用

module.exports = {
    name: 'stats',
    description: 'React to a message',
    execute(message, client) {
        message.channel.send(`Server count: ${client.guilds.size}`);
    },
};

Answer 2

cache 属性之前的内容是 undefined。

所以在你的情况下是 client.guilds。鉴于不能为正确的 djs 客户端对象取消定义，您在调用该文件时可能没有以正确的顺序传递您的值。也就是说，client 可能不是真正的 djs 客户端 class/object.
