当我在Mac上使用render {rmarkdown}从.Rmd文件生成pdf文件时，出现错误消息

When I use the render{rmarkdown} to produce pdf file from .Rmd file on my Mac, an error message says

pandoc: pdflatex not found. pdflatex is needed for pdf output. Error: pandoc document conversion failed

pandoc: pdflatex not found. pdflatex is needed for pdf output. Error: pandoc document conversion failed

但是，当我与

pdflatex -v

我知道了

pdflatex已安装在我的计算机中.

The pdflatex is installed in my machine.

任何人都可以帮助告诉我如何告诉R在哪里找到pdflatex吗?

Can anyone help to tell how can I tell R where to find the pdflatex?

非常感谢！

推荐答案

升级到OS X Mavericks后，我发现pdflatex缺失"问题(例如，在RStudio中检查软件包的构建时，我收到了error tools::texi2pdf pdflatex missing消息).

I found I was having issues with pdflatex "missing" after I upgraded to OS X Mavericks (e.g. when checking package builds in RStudio I was getting an error tools::texi2pdf pdflatex missing message).

1. 检查是否存在/usr/texbin.
   在终端中:

1. Check that /usr/texbin exists.
   In terminal:

cd /usr/texbin

如果没有这样的文件或目录"，那么您将需要创建指向安装的texbin的符号链接.我的在/Library/TeX/Distributions/.DefaultTeX/Contents/Programs/texbin
在终端中:

If "No such file or directory" then you will need to create a symbolic link to your installation's texbin. Mine was in /Library/TeX/Distributions/.DefaultTeX/Contents/Programs/texbin
In terminal:

ln -s /Library/TeX/Distributions/.DefaultTeX/Contents/Programs/texbin /usr/texbin

在终端中，检查echo $PATH的结果.确保存在/usr/texbin.如果不存在，则需要在PATH变量中添加/usr/texbin.

In terminal, check the result of echo $PATH. Make sure that /usr/texbin is present. If it isn't present, then you need to add /usr/texbin to your PATH variable.

如果发现自己必须弄乱PATH变量，则可以安装最新版本的 MacTex 成为更好的解决方案.

If you find yourself having to mess with the PATH variable, installing the latest version of MacTex might be a better solution.

更新:OS X 10.11 El Capitan不再允许对/usr的写操作，因此最新版本的MacTeX(2015)现在在此系统上写了指向/Library/TeX/texbin而不是/usr/texbin的链接.

UPDATE: OS X 10.11 El Capitan no longer allows writes to /usr so the latest version of MacTeX (2015) now writes a link to /Library/TeX/texbin instead of /usr/texbin on this system.
