当出现“资源路径中未找到文件”错误时如何解决问题？

Question

当我在 rmarkdown 文档中运行时knit，它一开始似乎可以工作，但最终会显示以下错误消息。

output file: paper-1_revised.knit.md

File  not found in resource path
Error: pandoc document conversion failed with error 99
Execution halted

我检查了几乎所有路径中使用的图片\includegraphics，但它们对我来说似乎是正确的。有什么方法可以修复或找到代码中资源路径问题所在的位置吗？
