Devtools not detecting that Rtools is the correct version with Microsoft R

[mattfidler]

For some reason there are people who install Rtools to a non-standard directory with microsoft R and add it to their path, it says it is a non-supported version of Rtools. This is reported here:

https://github.com/nlmixrdevelopment/nlmixr/issues/70

I'm letting you know for awareness. At the very least, the error message does not make sense:

#WARNING: Rtools 3.5 found on the path at C:/Apps/R/Rtools_3.5/Rtools is not compatible with R 3.5.1.

#Please download and install the appropriate version of Rtools from http://cran.r-project.org/bin/windows/Rtools/, remove the incompatible version from your PATH.
#Installation failed: Could not find build tools necessary to build RxODE

How can anybody think that forcing users to install in the root directory is an acceptable practice? I don't think you should describe the C:\Rtools directory as the standard directory. It should be described as non-standard and forced on users by bad programming practices.

Do you think this is a devtools programming error? Do you know if anybody ever got devtools to work with Rtools not in C:\?

The directory Rtools is installed is not the problem and devtools does not even require that Rtools be on your PATH.

I believe this is simply a duplicate of https://github.com/r-lib/devtools/issues/1772, please try that workaround or updating to the development version of devtools and see if that fixes your issue.

Thank you @jimhester . Hopefully it makes it on CRAN soon.

Hi,

the workaround seems like not working for me. or there is something i did wrong.

I used the code below as mentioned by previously and get a TRUE.

but the error still occurs.

`

yes, I also got the same error as @luckygoh. In my case, find_rtools gave TRUE, but whenever I tried to install packages through GitHub using devtools, it installed other packages (such as Rcpp) and crashed R.
