我需要同时渲染一个.qmd文件到gfm（.md）和.html，但是当我渲染.html文件时，夸托删除了现有的.md。有什么方法可以同时保持这两种格式吗？
夸托网站似乎表明这是可能的：https：//quarto.org/docs/get-started/authoring/rstudio.html#rendering，但我在让它工作时遇到了麻烦。
这是我的档案：

format_test.qmd

---
title: "format_test"
format:
  html: default
  gfm: default
---

## Quarto

Quarto enables you to weave together content and executable code
into a finished document. To learn more about Quarto 
see <https://quarto.org>.

## Running Code

When you click the **Render** button a document will 
be generated that includes both content and the output 
of embedded code. You can embed code like this:

```{r}
1 + 1

到目前为止我尝试过的：

1.在RStudio中点击Render：

• 生成一个带有gfm标签的.html文件。但是，单击gfm标签会导致一个空白页面，其中包含“未找到”。Screenshot of HTML render

我的工作目录有一个format_test.html文件，但没有format_test.md文件：

list.files()

[1] "format_test_files" "format_test.html"  "format_test.qmd"  
[4] "format_test.Rproj"

2.终端渲染：结果同上。

quarto render format_test.qmd --to gfm,html

processing file: format_test.qmd
                                                                                                            
output file: format_test.knit.md

list.files()

[1] "format_test_files" "format_test.html"  "format_test.qmd"  
[4] "format_test.Rproj"

3.单独渲染：夸托删除.md文件并将其替换为.html

这个命令给了我一个format_test.md文件：

quarto render format_test.qmd --to gfm

processing file: format_test.qmd

output file: format_test.knit.md

pandoc
to: \>-
commonmark+autolink_bare_uris+emoji+footnotes+gfm_auto_identifiers+pipe_tables+strikeout+task_lists+tex_math_dollars
output-file: format_test.md
standalone: true
default-image-extension: png
toc: true
number-sections: true

metadata
title: format_test

Output created: format_test.md

ls

format_test.Rproj       format_test.md          format_test.qmd

运行此命令将删除format_test.md，并将其替换为format_test.html。

quarto render format_test.qmd --to html

processing file: format_test.qmd

output file: format_test.knit.md

pandoc
to: html
output-file: format_test.html
standalone: true
section-divs: true
html-math-method: mathjax
wrap: none
default-image-extension: png

metadata
document-css: false
link-citations: true
date-format: long
lang: en
title: format_test

Output created: format_test.html

ls
format_test.Rproj       format_test.qmd
format_test.html        format_test_files
