I'm getting the following error when installing packages from github:

> devtools::install_github("pmartinezarbizu/pairwiseAdonis/pairwiseAdonis")
Downloading GitHub repo pmartinezarbizu/pairwiseAdonis@HEAD
Erro: Failed to install 'pairwiseAdonis' from GitHub:
  System command 'Rcmd.exe' failed, exit status: -1, stdout + stderr empty

With find_rtools, I get the following message (I was reading these posts, but couldn't solve my problem: https://github.com/r-lib/devtools/issues/2031 and R CMD check not looking for gcc in Rtools directory):

> find_rtools(T)

I'm using R v. 3.6.:

  • You need to add the R bin directory to your PATH. It is something like `file.path(R.home(), "bin/x64")`. (Use `list.files()` to make sure `Rcmd.exe` is there to confirm.) – user2554330 Jul 29 '20 at 23:47
  • What version of `devtools` are you running? – MrFlick Jul 29 '20 at 23:49

    Devtools v. 2.3.1 I did try to include what I thought was necessary in the PATH. I think the problem is with my PATH variables, but I am afraid to make things worse by removing things. These are the variables there (but there are more, e.g. python): > Sys.getenv('PATH') [1] "C:\\usr\\bin;C:\\Program Files\\R\\R-3.6.3\\bin\\x64; C:\\Rtools\\bin; C:\\RBuildTools\\3.5\\bin; C:\\Rtools\\bin;C:\\Rtools\\mingw_64\\bin; C:\\Rtools\\mingw_64\\bin\\gcc; C:\\Program Files\\R\\R-3.6.3\\bin\\x64; C:\\Program Files\\R\\R-3.6.3\\bin\\x64\\Rcmd.exe; C:\\Program Files\\R\\R-3.6.3\\bin – Thiago DeRoure BandeiradeMello Jul 30 '20 at 10:07

If anyone's still having this problem, I was able to work around it using the pak package with the pkg_install function. It's possible this might not work for all package repositories, but it has worked for the ones I've needed it for.
