natbib似乎不pdf_book /艺品正常工作(natbib seems to not work

在我.Rmd文件，我指的位置名为.bib文件如下：“让我举一个文章：[@ SampleTitle2016]”

当我编织当前的'，我想有地方被\提供文章被引用的引用，\ citep或\ citet命令.tex文件。

我注意到，如果我省略了线：在输出PARAMS“citation_package natbib”，引文作为原始文本提供：

但是，如果加提到线，.tex文件看起来更好，但由于某些原因，书目无法正确显示/（编译） - “什么？”我见而不是正确的引文：

我.Rmd如下所示：

---
title: "Sample document"
abstract: "This is a sample abstract \\newline This is the second line of abstract \\par \\textbf{Keywords:} keywordA, keywordB"
author:
  - name: Mateusz Kędzior
    email: alice@example.com
    affiliation: Some Institute of Technology
    footnote: Corresponding Author
bibliography: bibliography_escaped.bib
output:
  bookdown::pdf_book:
    base_format: rticles::elsevier_article
    keep_tex: true
    citation_package: natbib
---

## Sample Text

Let me cite an article: [@SampleTitle2016].

Without natbib, in .tex file citep  command is not used in output .tex file.

An with natbib, it seems there's problem with bibliography compilation.
