我正在尝试运行，devtools::install_github("gaborcsardi/notifier")但 R 似乎无法正确识别 RTools；位于C:\Rtools.
按照https://github.com/r-lib/devtools/issues/1772上的说明操作后，pkgbuild::find_rtools()使用devtoolsand的 CRAN 版本运行仍然给我以下错误pkgbuild：
Error in rethrow_call(c_processx_exec, command, c(command, args), stdin, :
Command not found @win/processx.c:977
