Rstudio 无法识别 MacTeX MacOSx 10.7.5，无法预览 pdf

Question

我已经创建了一个 .md 文件，但要以 pdf 格式预览它，Rstudio 需要安装 MacTeX。我已经安装了它，阅读自述文件，一切都在那里，终端显示所有包，但 Rstudio 没有看到，并产生以下消息。如何同步这两个程序？如何让 Rstudio 检测到 MacTeX 在那里？

--to latex --from markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash-implicit_figures --output HelloWorld.pdf --template /Library/Frameworks/R.framework/Versions/3.1/Resources/library/rmarkdown/rmd/latex/default.tex --highlight-style tango --latex-engine pdflatex --variable 'geometry:margin=1in'
pandoc: pdflatex not found. pdflatex is needed for pdf output.
Error: pandoc document conversion failed with error 41
Execution halted

No TeX installation detected (TeX is required to create PDF output). You should install a recommended TeX distribution for your platform:

  Windows: MiKTeX (Complete) - http://miktex.org/2.9/setup
  (NOTE: Be sure to download the Complete rather than Basic installation)

  Mac OS X: TexLive 2013 (Full) - http://tug.org/mactex/
  (NOTE: Download with Safari rather than Chrome _strongly_ recommended)

  Linux: Use system package manager

我使用 Mac OS X 10.7.5谢谢你!

令人尴尬的答案是多么简单!安装 MacTeX 程序后重启 Rstudio 即可。完成，pdf 创建。
