output file: /Users/xxx/Desktop/R_meetup/documentation/test2.tex

Warning message:
In test_latex_pkg("framed", system.file("misc", "framed.sty", package = "knitr")) :
  unable to find LaTeX package 'framed'; will use a copy from knitr

我在OSX Lion 10.7.3上

kpsewhich的路径：

   $ which kpsewhich
    /usr/texbin/kpsewhich


$ which pdflatex
/usr/texbin/pdflatex

这两个路径都位于.bash_profile目录中的home。我的Tex安装中有框架包。

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

解决方案

将此添加到我的.rprofile修复它：

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

Answer 1

仅供参考，现在knitr会自动将/tex/texbin添加到PATH for Mac OS（如果它不在PATH中。

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也应该在Mac OS上逐字处理。

为什么knitr无法找到framed.sty或kpsewhich？
