已安装 Rcpp Rtools 但未找到错误消息 g++
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.
