r - 无法安装 rtools

Question

我需要安装 Rtools 但我没有成功。

当我运行它时，它可以工作

library(devtools)
find_rtools()
[1] TRUE

当我加载库时，它也可以正常工作。但是当我运行需要 rtools 的代码时，我得到：

Error in sourceCpp(code = code, env = env, rebuild = rebuild, cacheDir = cacheDir,  : 
  Error 1 occurred building shared library.
WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:

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

当我尝试安装 rtools 时，我得到了这个：

Warning in install.packages :
  package ‘Rtools’ is not available (for R version 3.5.2)

解决方案

设置路径解决了这个问题。谢谢@red_quark

RStudio 未检测到 Rtools
