将TeX路径添加到R Studio-Ubuntu [英] Add TeX path to R Studio - Ubuntu

问题描述

我遇到的问题与这个问题:

当我打开任何.Rnw文件时，R Studio表示我没有安装TeX发行版:我正在使用带有Gnome的Ubuntu 14.04和TeXLive 2014.

When I open any .Rnw file, R Studio says that I have no TeX Distribution installed: I'm using Ubuntu 14.04 w/ Gnome and TeXLive 2014.

我在Renviron.site文件中加入了行PATH=/usr/local/texlive/2014/bin:${PATH}，现在看起来像这样:

I include the line PATH=/usr/local/texlive/2014/bin:${PATH} in the Renviron.site file, which now looks like:

##                      Emacs please make this -*- R -*-
## empty Renviron.site for R on Debian
##
## Copyright (C) 2008 Dirk Eddelbuettel and GPL'ed
##
## see help(Startup) for documentation on ~/.Renviron and Renviron.site

# ## Example ~/.Renviron on Unix
# R_LIBS=~/R/library
# PAGER=/usr/local/bin/less

# ## Example .Renviron on Windows
# R_LIBS=C:/R/library
# MY_TCLTK="c:/Program Files/Tcl/bin"

# ## Example of setting R_DEFAULT_PACKAGES (from R CMD check)
# R_DEFAULT_PACKAGES='utils,grDevices,graphics,stats'
# # this loads the packages in the order given, so they appear on
# # the search path in reverse order.

PATH=/usr/local/texlive/2014/bin:${PATH}

但是问题仍然存在.如何解决此问题并运行Sweave或knitR?

However the problem persists. How can I fix this and run Sweave or knitR?

推荐答案

如果有人遇到相同的问题，我打开R Studio并使用

If anyone faces the same problem, I opened R Studio and checked the pdflatex installation with

> Sys.which("pdflatex")
pdflatex 
  "" 

表明它实际上是空的，因此我运行命令Sys.getenv("PATH")来检查当前PATH:

Which show that it is in fact empty, so I run the command Sys.getenv("PATH")to check the current PATH:

Sys.getenv("PATH")
[1]   "/usr/local/texlive/2014/bin:/usr/local/texlive/2014/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"

要添加pdflatex路径，我必须在texlive目录中找到pdflatex文件，该文件为/usr/local/texlive/2014/bin/x86_64-linux，然后将其添加到当前路径中:

To add my pdflatex Path, I had to find the pdflatex file on my texlive directory, which was /usr/local/texlive/2014/bin/x86_64-linux, then I added this to my current Path:

> Sys.setenv(PATH=paste(Sys.getenv("PATH"),"/usr/local/texlive/2014/bin/x86_64-linux",sep=":"))

现在它可以完美运行

上面的解决方案仅适用于打开的会话，并且只是临时的，每次打开新的会话时都必须运行代码.我仍在寻找永久解决方案

the solution above works only for the open session and is only temporary, you have to run the code everytime you open a new session. I'm still trying to find a permanent solution
