graphicspath导致rmarkdown编译失败

Question

我正在R Studio中工作，使用rmarkdown创建投影仪幻灯片。当我声明多个图形路径（使用\graphicspath{{"path1"},{"path2"}})块中的header_includes时，Beamer PDF无法编译，出现“无法编译”错误。下面给出一个最小的工作示例。

我正在回顾大约10个月前创建的幻灯片-当时效果很好。

声明无路径有效：

只声明一个路径也是如此：

---
title: A plea for help
author: Minimum reproducible example
output: beamer_presentation
header-includes:
- \graphicspath{{"C:/Users/me"}}
---

## A plea for help

Help much appreciated

但是多个路径失败：

output: beamer_presentation
header-includes:
- \graphicspath{{"C:/Users/me"},{"C:/Users/you"}}
---

## A plea for help

Help much appreciated
