[英]No RTools compatible with R version 3.5.0 was found
I had problems installing data.table for R version 3.5.0, and was advised to check that RTools was properly installed. 我在安装R版本3.5.0的data.table时遇到问题,并建议检查是否正确安装了RTools。
After installing RTools 3.5 (this seems to be the latest) I typed 安装了RTools 3.5(这似乎是最新的)我输入了
find_rtools(T)
I got the following message: 我收到以下消息:
WARNING: Rtools is required to build R packages, but no version
of Rtools compatible with R 3.5.0 was found.
(Only the following incompatible version(s) of Rtools were found:3.4,3.5)
Please download and install the appropriate version of Rtools from
http://cran.r-project.org/bin/windows/Rtools/.
So on the one hand it looks like I do have 3.5 installed, but it seems to think there is a newer/different version. 所以一方面它看起来我安装了3.5,但它似乎认为有一个更新/不同的版本。
Any thoughts? 有什么想法吗?
The problem was Rtools 3.5
was not in your Windows system PATH
thus find_rtools
couldn't find it. 问题是
Rtools 3.5
不在您的Windows系统PATH
因此find_rtools
无法找到它。 Another possibility was that an incompatible version of Rtools
was in the PATH
另一种可能性是,
PATH
中存在不兼容的Rtools
版本
Best practice for installing Rtools
: 安装
Rtools
最佳实践:
Install RTools
at default recommended location (at the root of your C
drive): C:/Rtools/
在默认的推荐位置安装
RTools
(在C
盘的根目录下): C:/Rtools/
< Important > Check the box that allows Rtools
to modify system PATH < 重要 >选中允许
Rtools
修改系统路径的框
After the installation, we can double check by running this command inside R
安装完成后,我们可以通过在
R
里面运行这个命令来仔细检查
R> Sys.getenv('PATH')
[1] "C:\\Program Files\\R\\R-3.5.0\\bin\\x64;c:\\Rtools\\bin;c:\\Rtools\\mingw_64\\bin;

UPDATE UPDATE
The utility find_rtools
has been moved to the package pkgbuild
(as noted in devtools
News ). 实用程序
find_rtools
已移至包pkgbuild
(如devtools
News中所述 )。 The function pkgbuild::find_rtools()
correctly discovers Rtools
3.5 in my system. 函数
pkgbuild::find_rtools()
在我的系统中正确发现了Rtools
3.5。
Old answer 老答案
I had this same problem and it occurs because devtools
has not been updated to consider the newest version of RTools (3.5). 我有同样的问题,因为
devtools
尚未更新以考虑最新版本的RTools(3.5)。 Here is an easy fix that should work while they update the package: 这是一个简单的修复,它应该在更新包时起作用:
# add missing RTools 3.5 info
v_i = devtools:::version_info
v_i[["3.5"]] = v_i[["3.4"]]
v_i[["3.5"]]$version_max = "3.5.99"
assignInNamespace(x = "version_info",
value = v_i,
ns = "devtools")
# now find_rtools should work properly
devtools::find_rtools()
Of course, this approach assumes that devtools::find_rtools
worked for you before updating R and RTools. 当然,这种方法假设
devtools::find_rtools
在更新R和RTools之前为您工作。 If this is not the case, then you might have a faulty installation and/or PATH variable as others have mentioned. 如果不是这种情况,那么您可能会遇到其他人提到的错误安装和/或PATH变量。
I'm quite sure RTools 3.5 works with R-3.5 . 我很确定RTools 3.5适用于R-3.5。 I haven't used find_rtools() before, but I did manage to compile data.table from source a week ago.
我之前没有使用过find_rtools(),但我确实设法在一周前从源代码编译data.table。 Here's how I did it:
我是这样做的:
After installing R 3.5 and RTools 3.5, I manually checked/modified the following system-envs (somehow the RTools installer failed to do this automatically, so I went through the readme from RTools and do it manually): BINREF = "C:/Rtools/mingw_$(WIN)/bin/" (with "s, slashes are /) PATH = ";C:\\Rtools\\bin" ("s are optional , slashes are \\ ) 安装R 3.5和RTools 3.5之后,我手动检查/修改了以下system-envs(不知何故,RTools安装程序无法自动执行此操作,因此我从RTools读取了自述文件并手动完成):BINREF =“C:/ Rtools / mingw _ $(WIN)/ bin /“(带”s,斜杠是/)PATH =“; C:\\ Rtools \\ bin”(“s是可选的,斜杠是\\)
Then I downloaded the source package for data.table(was version 1.10.4-3) and ran R CMD INSTALL data.table_1.10.4-3.tar.gz from windows command-line. 然后我下载了data.table的源包(版本为1.10.4-3),并从windows命令行运行了R CMD INSTALL data.table_1.10.4-3.tar.gz。 With a working RTools, the package would successfully compile.
使用工作的RTools,包将成功编译。 I also tried the install.packages(data.table) from R-GUI, where I got pop-up window to confirm compilation from source.
我还尝试了来自R-GUI的install.packages(data.table),我在弹出窗口中确认从源代码编译。
Anyway, I believe cran now provides a working windows-binary for data.table, so using RTools is no longer necessary. 无论如何,我相信cran现在为data.table提供了一个工作的windows-binary,因此不再需要使用RTools。
