javascript - 需要帮助将 Bot 更新到 Discord.js v12

问题描述

我正在尝试更新此代码以使用 Discord.js v12。我遇到了一个错误，我对如何解决这个错误有点困惑。我已经更新了一些代码以使用 Discord.js v12。

类型错误：client.channels.fetch(...).send 不是函数

解决方案

.fetch()返回一个Promise。
因此，您需要等待结果.then()。

在您的代码中（假设logsChannel是一个 ID）：

client.channels
    .fetch(logsChannel)
    .then(fetchedChannel => fetchedChannel.send(embed_delete));

目前，你需要更新你所有的.fetches
