Can not preview PDF for bookdown project

[hysci]

It was OK to preview/generate PDF files from bookdown project, such as https://github.com/rstudio/bookdown-demo.git, this proven that the environment in my computer was OK. (RStudio 1.1.442 + Miktex 2.9.6637 + pandoc 2.1.3)

However, when I used the latest RTVS + Visual studio 2017 (updated to Apr. 5th, 2018), I failed to preview PDF (R Tools -> Markdown -> Preview PDF)

R evaluation failed:
rtvs:::rmarkdown_publish(blob_id = 2, output_format = "pdf_document", encoding = 'cp65001')
Error: Failed to compile rmd_292c2548169b.tex

The (R Tools -> Markdown -> Preview PDF) seemed OK previewing "index.Rmd", but it only showed the single html file, not the whole book.

Did you figure out what the problem was? I'm struggling to resolve this issue as well.
