bibtext引用未在bookdown中处理

Question

我有一个书面记录文档，引用其他文档使用bibtex参考书目文件。它似乎根本没有进程，因为输出（gitbook格式和pdf）都没有将实际引用转换为引用。输出总是复制引文的纯文本，而不是实际的引用，如下所示：

这是一个最小的复制示例，我使用它构建：

Rscript -e 'bookdown::render_book("index.Rmd", "bookdown::gitbook")'

index.Rmd：

---
title: "test"
site: "bookdown::bookdown_site"
documentclass: book
bibliography: test.bib
biblio-style: apalike
link-citations: true
# toc: yes
# toc_depth: 2

# Introduction {#ch:intro}

Conference publication takes the lead role in describing innovative research,
while journals are often delegated to archival purposes [@vrettas15:conferences].


```{r echo=FALSE}
sessionInfo()
```

试验：围兜：

@article{vrettas15:conferences,
  title =    {Conferences versus journals in computer science},
  author =   {Vrettas, George and Sanderson, Mark},
  journal =  {Journal of the Association for Information Science and Technology},
  volume =   66,
  number =   12,
  pages =    {2674--2684},
  year =     2015,
  publisher =    {Wiley Online Library}
}

_bookdown.yml：

rmd_files: [
  "index.Rmd",
]
new_session: no
bookdown::gitbook:
  split_bib: no

Answer 1

原来是由于Pandoc的版本太低了。 1.19.x或更高版本应该可以解决问题。
