bibtext引用未在bookdown中处理

我有一个bookdown文档,它引用了使用bibtex书目文件的其他文档。它似乎根本没有过程,因为输出(gitbook格式和pdf)不会将实际引用转换为参考。输出总是复制引用的纯文本,而不是实际引用,如下所示:

下面是一个最小的复制示例,我使用以下方法构建该示例:

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

指数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()
```

测试:bib:

@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}
}
