r-markdown - Rmarkdown中美人鱼甘特图的渲染问题

Question

我正在尝试使用 DiagrammeR mermaid 在我的 Rmarkdown 中插入甘特图。问题是当我编织到 html 时，我的文本看起来都是灰色/透明的。我注意到当我删除标题的## 时，一切都很好。有人对我有解决方案吗？

这是代码模板：

---
title: "My title"
author: "J. Doe"
output:
  html_document:
    toc: no
bibliography: biblio.bib
--- 

```{r libraries, include=FALSE}
library(DiagrammeR)```


```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)```

<style>
body {
text-align: justify}
</style>
