【问题描述】：

有谁知道怎么回事？我正在使用这行脚本 -

client.on('presenceUpdate', (oldPresence, newPresence) => {
    let member = newPresence.member;
    if (member.id === '603517534720753686') {
        if (oldPresence && oldPresence.status !== newPresence.status) {
            channel = client.channels.cache.get('788547135234375712');
            let text = "";
            if (newPresence.status === "online") {
                text = "**Hello @everyone, Timer Bot is now online! Thank you for your patience.**";
            } else if (newPresence.status === "offline") {
                text = "**@everyone Due to issues, Timer Bot is currently offline. We apologize for the inconvenience.**";
            }
            channel.send(text);
        }
    }
});

每次我运行它时，我的控制台都会显示 -

/home/runner/TimerUtilities/index.js:32
            channel.send(text);
                    ^

TypeError: Cannot read property 'send' of undefined

看起来“频道”身份不明。有谁知道如何识别它？谢谢！

【解决方案1】：

试试这个

client.channels.get("ID").send("Your message")

【讨论】：

使用它时，我的控制台说 client.channels.get 不是一个函数。当我使用 client.channels.cache.get("My-Id").send("My-Message") 时，它说Cannot read property 'send' of undefined。

【解决方案2】：

尝试做 'message.channel.send(text)' 而不是 'channel.send(text)'？
