R Markdown：openBinaryFile：不存在（没有这样的文件或目录）

Question

我开发了一个闪亮的应用程序，允许用户通过R Markdown下载HTML报告。我正在尝试将自定义CSS和图像包含到我的rmarkdown文件中。但是，我不断收到此错误消息：

pandoc: Could not fetch (either css or image file)
openBinaryFile: does not exist (No such file or directory)

当我在R Studio上编织.rmd文件时，它可以引用所需的图像文件或CSS。但是，当我运行Shiny应用程序并下载html文件时，出现上述错误消息。我什至尝试将图像和CSS文件与.rmd文件放在同一工作目录中，但无济于事...

output:
  html_document:
   css: pandoc.css

(same error message as above)

一直在尝试为此找到解决方案，但似乎无法...有人可以在这里提供帮助吗？

Answer 1

我有一个类似的问题。我没有使用完整的文件路径。我正在使用〜/ path / to / file。我将其更改为完整路径（即删除了〜/），它可以正常工作。

Answer 2

I just had this issue as well, but for me the reason was that the RStudio project was on a shared drive, and I had opened it through the network location. The problem was resolved when I closed out of the project, and opened it back up through a mapped network drive. (If when you run getwd() your location starts with \\, this is probably what is happening to you.)
