R 未检测到 Rtools [英] Rtools not being detected by R

问题描述

更新:

我写了一个简短的演练指南来在 Windows 上安装 Rtools.

I've written a brief walkthrough guide to installing Rtools on windows.

原文:

我正在尝试在 Windows 7 上使用 RStudio 构建 R 包.当我尝试通过 RStudio 的构建面板构建包时，我收到:

I am trying to build an R package using RStudio on Windows 7. When I attempt to build the package via RStudio's Build panel I receive:

WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:

http://cran.rstudio.com/bin/windows/Rtools/

加载 library(devtools) 并运行 find_rtools(T) 给出:

Loading library(devtools) and running find_rtools(T) gives:

Scanning path...
ls : F:\Rtools\bin\ls.exe 
Scanning registry...
Found F:/Rtools for 3.1 
VERSION.txt
Rtools version 3.1.0.1936 
[1] TRUE

Path 变量设置为:

The Path variable is set as:

F:\Rtools\bin;F:\Rtools\gcc-4.6.3\bin;F:\Rtools\perl\bin;F:\Rtools\MinGW\bin;F:\Program Files\R\R-3.0.2\bin\x64;F:\Program Files (x86)\HTML Help Workshop;F:\Program Files\MiKTeX 2.9\miktex\bin\x64\;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Windows Live\Shared;C:\Program Files\Microsoft Network Monitor 3\;F:\Program Files (x86)\QuickTime\QTSystem\

我也重新启动了几次，但错误仍然存​​在.我有点不明白为什么会这样.

I've also restarted several times, yet the error persists. I'm a bit confused as to why this is occurring.

R访问系统变量Path时的输出:

推荐答案

事实证明，当我安装 RTools 时，我在安装中遗漏了 R 2.15.x+ 工具链选项，这导致 gcc 从未安装过.如果 RStudio 无法注册 RTools，希望这篇文章可以作为诊断指南.

Turns out when I installed RTools I left out the R 2.15.x+ toolchain option in the installation, which lead to the gcc never being installed. Hopefully, this post will serve as a diagnostic guide if RStudio fails to register RTools.
