Error in yaml::yaml.load(..., eval.expr = TRUE)

[MatixR]

Hi, When I try to use the paper_zh on Mac OS , I meet a problem with YAML.

I use the flowing code to generate the template. bookdownplus(template = 'paper_zh', to = "chinese_paper", render = FALSE) ,

When I try to produce a pdf document, I find the following erorr:

n*** Successfully loaded .Rprofile ***n Error in yaml::yaml.load(..., eval.expr = TRUE) : Parser error: while parsing a block mapping at line 12, column 3 did not find expected key at line 20, column 4 Calls: <Anonymous> ... parse_yaml_front_matter -> yaml_load -> <Anonymous> Execution halted

By the way, I have changed the YAML setup in the index.md .

output: bookdown::pdf_book:

I am sorry that I don't have a mac and this issue cannot be tested.
