r-为什么编织一个pdf_document要花很长时间

Question

我正试图在RStudio中编织一个pdf_document，但它花了很长时间，只限于编织第一个chunck？我尝试重新安装RStudio并删除.Rhistory，但仍然无法工作。你知道为什么它不能生成pdf文档以及如何解决问题吗？

这是rmarkdown文件：

author: "Author"
date: "29/5/2020"
output:
pdf_document:
fig_caption: yes
extra_dependencies:

- OT1
float: null

我能给你的最大帮助就是你陷入了库块的困境。所以，试着一次从那里删除一个元素，直到你越过那个块，看看哪一行有问题。
