已安装 Rcpp Rtools 但未找到错误消息 g++

问题描述

我已经查阅了与我的具体问题相关的现有 SO 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.

我正在尝试在我的工作机器上执行此操作，我的管理员权限有限，但我可以运行 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.

所有的 R、Rstudio 和 Rtools 都安装在 C:/WORK/中，这是我拥有一些有限管理员权限的地方.

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，我设置了:

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;" 

当我跑步时

 system('where make')

我明白了

 C:WORKRtoolsinmake.exe

当我跑步时

 system('g++ -v')

我明白了:

 Using built-in specs.

当我编译时，我得到这个错误:

When I compile, I get this error:

 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 还在寻找 g++

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

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

我不是已经设置了 R 来查找它吗

Didn't I already set R to look for it in

 C:/WORK/Rtools? 

即使我手动添加了

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

在 ENV 变量中，我仍然遇到同样的错误.(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.)

有人遇到过这个问题吗?

Has anyone run into this specific issue?

推荐答案

路径 c:/Rtools/mingw_64/bin/ 硬编码到文件 Makeconf位于 R 安装中的某个位置(在我的情况下为 C:ProgsRR-3.4.1etcx64)，作为变量 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:ProgsRR-3.4.1etcx64), as the value of the variable BINPREF.

最简单的做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/).这适用于我全新安装的 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.
