问题描述

我似乎无法让preview_chapter从事我的Bookdown项目。这是我的_bookdown.yml文件：

book_filename: "thesis"
delete_merged_file: true
output_dir: "docs"
new_session: yes 

rmd_files: # defines the .Rmd files to be included for each output format
  html: ["index.Rmd","02-methodology.Rmd","03-results.Rmd","99_references.Rmd"]

当我使用时：

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

整本书正确编译。但是，如果我尝试按以下步骤构建单个章节：

 bookdown::preview_chapter("03-results.Rmd",bookdown::'gitbook')

我得到：

Error in files2[[format]] : 
  attempt to select less than one element in get1index

我使用的语法不正确吗？

解决方法

bookdown::'gitbook'应该是'bookdown::gitbook'。
