已安装Rcpp Rtools，但未找到错误消息g ++ [英] Rcpp Rtools installed but error message g++ not found

问题描述

我已经咨询了与我的特定问题相关的SO的现有条目，但仍然无法解决.

I have consulted existing entries on SO related to my specific issue, but still could not resolve it.

我正在尝试使用具有有限管理员权限的计算机在工作，但是我可以运行Rtools.exe，所以我安装了它.

I am trying to do this with my machine at work, where I have limited admin rights, but I can run Rtools.exe, so I installed it.

我对R的设置是:

 platform       x86_64-w64-mingw32          
 arch           x86_64                      
 os             mingw32                     
 system         x86_64, mingw32             
 version.string R version 3.3.0 (2016-05-03)

我是RStudion版本0.99.902.我安装了Rtools版本3.3.0.1959.

I am RStudion Version 0.99.902. I installed Rtools version 3.3.0.1959.

所有R，Rstudio和Rtools都安装在C:/WORK/中，在这里我具有一些有限的管理员权限.

All of R, Rstudio, and Rtools are installed in C:/WORK/, which is where I have some limited admin rights.

在我的系统ENV变量中，我已设置:

In my system ENV variable, I have set up:

 C:\\WORK\\Rtools\\bin; C:\\WORK\\Rtools\\gcc-  4.6.3\\bin; C:\\WORK\\R-3.3.0\\bin\\x64;" 

我跑步时

 system('where make')

我知道

 C:\WORK\Rtools\bin\make.exe

我跑步时

 system('g++ -v')

我得到:

编译时出现此错误:

 Error in compileCode(f, code, language = language, verbose = verbose) : 
 Compilation ERROR, function(s)/method(s) not created!
 c:/Rtools/mingw_64/bin/g++: not found

我的问题是:为什么R还在

My question is: why is R still looking for g++ in

 c:/Rtools/mingw_64/bin/g++

我不是已经设置R在

 C:/WORK/Rtools? 

即使是我手动添加

 c:/WORK/Rtools/mingw_64/bin/g++

在ENV变量中，我仍然遇到相同的错误. (由于管理员权限，我无法在C:/中创建Rtools文件夹.)

in the ENV variable, I still got the same error. (I cannot make Rtools folder in C:/ due to admin rights.)

有人遇到这个特定问题吗?

Has anyone run into this specific issue?

推荐答案

路径c:/Rtools/mingw_64/bin/硬编码为R安装(在我的情况下为C:\Progs\R\R-3.4.1\etc\x64)中某个位置的文件Makeconf中. BINPREF的值.

The path c:/Rtools/mingw_64/bin/ is hard-coded into the file Makeconflocated somewhere in the R installation (in my case C:\Progs\R\R-3.4.1\etc\x64), as the value of the variable BINPREF.

最简单的方法是将此路径更改为您的路径C:/WORK/Rtools/bin(在我的情况下是C:/Progs/RTools/3.4/mingw_64/bin/).这对我来说是全新安装的R-3.4.1和Rtools3.4以及一个最小的示例.

The easiest thing to do is to change this path to your path C:/WORK/Rtools/bin (in my case was C:/Progs/RTools/3.4/mingw_64/bin/). That worked for me in a fresh installation of R-3.4.1 and Rtools3.4, and a minimal example.
