NPM UnhandledPromiseRejectionWarning

Question

我在虚拟机和AWS上设置了一个20.04Ubuntu服务器，以运行不再由开发人员托管的uno。(https://github.com/Exium1/UnoBot)我一直在遵循别人关于如何设置它的指南(https://github.com/DaanWet/UnoBot/blob/master/documentation/Install.md)，但是当我启动它时，它失败了。

我得到以下错误：

(node:14998) UnhandledPromiseRejectionWarning: DiscordHTTPError: 401 Unauthorized on GET /api/v9/gateway/bot

cess with a non-zero exit code.

有人能帮忙解决这个问题吗？

Answer 1

为了解决已记录的UnhandledPromiseRejectionWarning警告，您可以通过在代码中添加以下内容来修复它：

process.on("unhandledRejection", console.error);

这将更清楚地记录错误，并将防止您的控制台被这些警告填满。

至于@mmenschig所说的话，它们确实是正确的。确保将正确的令牌传递到<Client>.login()中。
