然而,当我按Ctrl+Shift+B在RStudio中构建包时,我被告知找不到Rtools:

以前关于这个问题的文章(见: Rtools not being detected by R R 3.3.0 installing a package on Windows: gcc not found error ). 在我的例子中,在显示系统路径的代码下面,两个工具链框都被选中(参见图)。

RStudio cannot find Rtools to build package

有人能为Rstudio中检测rtools的解决方案提供建议吗?

我以这种方式对问题进行了分类,部分是根据对以下问题的评论:

Rtools not being detected by R

既然如此 devtools::find_rtools() 回报 TRUE Rcpp ( https://thecoatlessprofessor.com/programming/installing-rtools-for-compiled-code-via-rcpp/ )作品:

Sys.which("ls.exe") 和 Sys.which("gcc.exe") . 前者应该返回一条路径,但后者可能是空的,这就是问题所在。

然后我又找到了 gcc.exe C:\Rtools\mingw_64\bin ,这有点疯狂)并将其复制到 C:\Rtools\bin ,这正是RStudio想要的。那就是 ls.exe 使用 Sys.which
