将rmarkdown编织为html时，选项卡未呈现 [英] Tabs not rendering when knitting rmarkdown to html

问题描述

我一直在使用rmarkdown和knitr创建html输出.突然之间，{.tabset}函数在编织时似乎已停止工作，并且文档呈现没有该选项的状态.

I've been using rmarkdown and knitr to create html output. Quite suddenly, the {.tabset} function seems to have stopped working when knitting, and documents render as they would without this option.

这是一个简单的示例，在我的系统上无法正常运行.

Here is a simple example that does not work as it should on my system.

---
title: "Plot Tabs"
output: html_document
---

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

## Title {.tabset .tabset-fade .tabset-pills}

### tab 1

```{r}
plot(cars)
```

### tab 2

```{r}
plot(pressure)
```

我已经在另一个系统上对此进行了测试，并且工作正常.我还重新安装了R并更新了我的所有软件包以及RStudio.

I've tested this on another system, and it works fine. I've also reinstalled R and updated all my packages as well as RStudio.

有人知道任何类似的问题或任何可能导致该问题的东西吗?

Does anyone know of any similar issues, or anything that could be causing the problem?
