我在使Rtools运行时遇到问题。我已经搜索了SO和其他网站，但仍然无法深入了解该问题。
我正在使用R版本3.6.1，并尝试安装Rtools35。我正在使用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。
我已经在C：\ Rtools中安装了具有管理权限的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文件，并将其放在Rtools \ bin中（如一篇文章所建议。
运行：
Sys.getenv('PATH')

在RStudio not finding RTools之后，
`Sys.which("ls.exe")`
> C:\\Rtools\\bin\\ls.exe
Sys.which("gcc.exe")
> "C:\\Rtools\\bin\\gcc.exe"
似乎已安装RTools：
library(devtools)
find_rtools()
> [1] TRUE
但是，在Rcpp中进行简单评估会引发错误。正在运行：
library(Rcpp)

我已经重新启动计算机，并尝试重新安装Rtools几次。我不知道下一步该怎么做。
