请让我知道，如果你看到任何明显的错误，或者我可能会继续解决这个问题。我甚至不知道从哪里开始。谢谢。

正如错误所说的
错误：找不到模块“../../controllers/theAudioDbController”
。检查文件名是否正确。

如错误所示
错误：找不到模块“../../controllers/theAudioDbController”
。检查文件名是否正确。

错误就在那里
错误：找不到模块“../../controllers/theAudioDbController”
我现在看到实际的文件名是“theAudioDbController”。我解决了这个问题，现在再试一次。编辑：这确实解决了问题。多么愚蠢的错误啊。非常感谢。我相信这是你这个月帮我解决的第二个问题。我写这篇文章是为了回答这个问题，以便将来人们能找到它。如果你喜欢，你可以把它标记为正确的。P.S-是的，这是一个月内的第二次LOL错误就在那里
