安装Rtools时出错

Question

我很难让Rtools发挥作用。我已经搜索过这样和其他的网站，但仍然找不到这方面的真相。

我正在使用RVersion3.6.1，并试图安装Rtools 35。我使用的是RStudio 1.0.143，但是在R控制台中运行代码不会产生不同的结果。

我在C中安装了带有管理权限的Rtools：\ Rtools\bin、Rtools\mingw_32\bin和Rtools\mingw_64\bin都在PATH中。gcc编译器安装在mingw_32和ming_64二进制文件中，我从mingw_32文件夹中复制了一个，并将其放入Rtools\bin (如一篇文章所建议的那样)。

跑步：

Sys.getenv('PATH')

> C:\\Users\\robin.ghertner\\Documents\\R\\R-3.6.1\\bin\\x64;C:\\oracle\\product\\11.2.0\\client_1\\BIN;C:\\Program Files (x86)\\Common
> Files\\Oracle\\Java\\javapath;C:\\Windows\\System32;C:\\Windows;C:\\Windows\\System32\\wbem;C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\;C:\\Windows\\System32\\OpenSSH\\;C:\\Program

继RStudio not finding RTools之后，

`Sys.which("ls.exe")`

> C:\\Rtools\\bin\\ls.exe

Sys.which("gcc.exe")

> "C:\\Rtools\\bin\\gcc.exe"

它看起来像是安装了RTools：

library(devtools)
find_rtools()

> [1] TRUE

但是，在Rcpp中执行一个简单的评估会引发一个错误。跑步：

library(Rcpp)
evalCpp("1+1",showOutput = T)

我已经重新启动了我的计算机，并尝试重新安装Rtools几次。我不知道下一步该做什么。

Answer 1

需要检查文件夹name(C:/Rtools40/usr/bin)的

1. ，您需要检查所使用的位。(32位或64位)

1. https://github.com/r-windows/docs/blob/master/rtools40.md#readme ->您应该打开pacman并遵循pacman命令

1. ，如果仍然有错误，则需要检查生物导体版本，以便可以计算出out..maybe

​

 if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")
BiocManager::install(version = "3.11")
