我正在使用子 .Rmd 编​​译 pdf。example_child.Rmd调用图像使用并knitr::include_graphics()自行编译，但尝试编译example_main.Rmd会产生以下错误。

TeX Live 2019 is frozen forever and will no
longer be updated.  This happens in preparation for a new release.

If you're interested in helping to pretest the new release (when
pretests are available), please read https://tug.org/texlive/pretest.html.
Otherwise, just wait, and the new release will be ready in due time.
! LaTeX Error: File `images/example_image' not found.

Error: LaTeX failed to compile example_main.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See example_main.log for more info.
Execution halted

example_main.Rmd仅调用不调用图像的子文档时编译正常（它调用子文件夹中的数据就好了）。任何帮助，将不胜感激！关于我的会话和文件的所有相关信息如下：

我的工作目录是"/Users/example_project"

（example_main.Rmd文件路径"/Users/example_project/folder_1/example_main.Rmd"）YAML 和代码块如下：

---
output: 
  pdf_document:
    latex_engine: xelatex
---

```{r child = './folder_2/example_child.Rmd'}
```

（example_child.Rmd文件路径"/Users/example_project/folder_1/folder_2/example_child.Rmd"）YAML 和代码块如下：

---
output: pdf_document
---

```{r example, echo = FALSE, out.width='80%', out.height='50%'}
knitr::include_graphics("./images/example_image.png")
```

完整的图像文件路径是"/Users/example_project/folder_1/folder_2/images/example_image.png".

example_child.Rmd您可以使用子文档的工作目录（在 中）重建图像的路径

---
output: pdf_document
---

```{r example, echo = FALSE, out.width='80%', out.height='50%'}
knitr::include_graphics(paste0(getwd(), "/images/example_image.png"))
```

似乎这是与此处和此处描述的类似的“孙子”文档的问题
