错误提示

[xukuang]

下载这个项目到自己电脑(window系统)上，什么文件也没有改动，只是打开了bookdown-chinese.Rproj文件，Rstudio就有如下的错误提醒：
[1] "LC_COLLATE=Chinese (Simplified)_People's Republic of China.936;LC_CTYPE=Chinese (Simplified)_People's Republic of China.936;LC_MONETARY=Chinese (Simplified)_People's Republic of China.936;LC_NUMERIC=C;LC_TIME=Chinese (Simplified)_People's Republic of China.936"
Error in yaml::yaml.load(string, ...) :
Scanner error: mapping values are not allowed in this context at line 2, column 7。、

发现Build Book后能正常运行，得到的结果也没问题。不知道这个错误提示是哪里出了问题？

吾日三省吾身做了没有：RStudio 最新版？R 最新版？所有 R 包都更新过了？

[xukuang]

RStudio升级到 1.0.143，R升级到3.4.0，所有包都升级到最新版（除了foreign包，貌似最新版不支持windows系统，没有升级）。上面的错误提醒依然存在，但运行结果依旧没有问题。对index.Rmd文件中的第二行内容重新输入一遍并从后前逐步删除其中的字符希望找出其中错误。发现当内容改为下面的情形时：
---
title: "麻麻"
author: "张三"
date: "r Sys.Date()"
documentclass: ctexbook
bibliography: [book.bib, packages.bib]
biblio-style: apalike
link-citations: yes
colorlinks: yes
lot: yes
lof: yes
geometry: [b5paper, tmargin=2.5cm, bmargin=2.5cm, lmargin=3.5cm, rmargin=2.5cm]
site: bookdown::bookdown_site
description: "一个简单的中文书示例。"
github-repo: yihui/bookdown-chinese
#cover-image: images/cover.jpg
---
又出现这样的错误提示：
Error in yaml::yaml.load(string, ...) :
Scanner error: while scanning a simple key at line 13, column 1could not find expected ':' at line 14, column 1
此时，删除第14行（description: "一个简单的中文书示例。"），就没有错误提示了。不删除第14行，仍有错误提示。

此外，在使用这个模板时发现，当index.Rmd文件中的title: "《R for Data Science》学习笔记"时也会出现类似的错误提示：

Error in yaml::yaml.load(string, ...) :
Scanner error: mapping values are not allowed in this context at line 2, column 7

而把书名号去掉，即title: "R for Data Science学习笔记"错误提示就会消失。

感觉字符编码遇见windows系统到处都是坑。

我找到问题所在了，但我没时间去深究。这个问题不影响你使用 bookdown 或者编译这个例子，所以你可以忽略这个错误。

好的，谢谢

我也碰到这个问题了~更新到最新版木有用 😢

@yihui
我按照https://bookdown.org/使用publish功能也报错了

> bookdown::publish_book(render = "local")
Error in yaml::yaml.load(string, ...) : 
  Scanner error: mapping values are not allowed in this context at line 2, column 7
