RuntimeError:托管在数字海洋上的Discord.JS中的内存越界错误

Question

我使用distube库编写了一个不和谐的音乐机器人，该库工作正常，没有在本地主机或heroku上显示此错误，但当我转到数字海洋时，它开始顺利工作，但过了一段时间，我开始收到与wasm-function和RuntimeError: memory access out of bounds相关的错误。我增加了屏幕截图和下面错误的代码，并提供了我为这个机器人编写的代码。我对wasm函数和内存访问越界错误几乎一无所知，所以如果有人能帮我解决这个问题，将会有很大的帮助。

不和谐上的错误消息

​

当我转移到数字海洋时，我才开始收到这个错误，而在此之前它并没有发生。

Answer 1

有几件事你可以支配：

• 确保您的数字海洋环境支持web组装(很可能是因为您说它最初运行得很好，但是如果不考虑这样要求的话：

var encoder = new OpusScript(samplingRate, channels, OpusScript.Application.AUDIO, {
  wasm: false
});

• 根据我的判断(通过研究控制台中的错误)，它主要发生在opusscript依赖项中，您可能希望切换到另一个操作系统引擎(如@discordjs/opus )，其中ytdl核/不和谐播放器是它的替代品，并且完全放弃distube作为依赖项。
• 如果错误不退出您的流程，并且一切正常运行，则完全抑制和忽略这些错误。
