我在 OSX Lion 10.7.3

kpsewhich 的路径：

   $ which kpsewhich
    /usr/texbin/kpsewhich


$ which pdflatex
/usr/texbin/pdflatex

两条路径都在我.bash_profile的home目录中。我的 Tex 安装中确实有框架包。

PATH=$PATH:/usr/texbin/pdflatex
PATH=$PATH:/usr/texbin/kpsewhich
export PATH

解决方案

将此添加到我的.rprofile修复中：

Sys.setenv("PATH" = paste(Sys.getenv("PATH"),"/usr/texbin",sep=":"))

Answer 1

仅供参考，如果knitrMac OS 尚未在./tex/texbinPATHPATH

Answer 2

安装texlive-latex-extra为我解决了。原始答案（https://stackoverflow.com/a/25517332/1169233）适用于 Ubuntu，但 AFAIK 它也应该在 Mac OS 上逐字运行。
