Devtools: find_rtools() doesn't recognize Rtools 3.5 in R 3.5.0

[krshedd]

I installed Rtools 3.5 from here, but when I run find_rtools() in the latest release of R 3.5.0 I get this

WARNING: Rtools is required to build R packages, but no version of Rtools compatible with R 3.5.0 was found. (Only the following incompatible version(s) of Rtools were found:3.1,3.2,3.3,3.4,3.5) Please download and install the appropriate version of Rtools from http://cran.r-project.org/bin/windows/Rtools/.

[EricMarcon]

It seems that devtools:::version_info$3.5 is missing.

Also, devtools:::version_info$3.4$version_max is "3.4.99" so Rtools 3.5 cannot be used with R 3.4.4..

It seems to be the same issue as pkgbuild issue #38 but devtools has not been updated yet.

[jackwasey]

to be clear, a workaround is to use library(pkgbuild) with an updated pkgbuild after loading devtools

[krshedd]

Thanks for the workaround Jack, much appreciated. This allowed be to be able to use devtools::install_github to download other R packages from GitHub that require Rtools to build them.

Here is the code just in case anyone else has this issue.
install.packages("pkgbuild") # pkgbuild is not available (for R version 3.5.0)
install.packages("devtools") # make sure you have the latest version from CRAN
library(devtools) # load package
devtools::install_github("r-lib/pkgbuild") # install updated version of pkgbuild from GitHub
library(pkgbuild) # load package
find_rtools() # should be TRUE, assuming you have Rtools 3.5

I'll leave this issue open for now since this workaround doesn't really close the underlying issue.

[EricMarcon]

Unfortunately, it does not work on Windows: devtools::install_github("r-lib/pkgbuild") fails because the CRAN version of devtools does not accept either R 3.5 nor Rtools 3.5 to compile it.
We need a binary of pkgbuild on CRAN first to allow using Rtools.

I went back to R 3.4.4 and Rtools 3.4 until pkgbuild is on CRAN.

[aparpara]

This workaround works for me:
library(devtools)
assignInNamespace("version_info", c(devtools:::version_info, list("3.5" = list(version_min = "3.3.0", version_max = "99.99.99", path = "bin"))), "devtools")
find_rtools() # is TRUE now

[urwa]

Windows 10 x64
I was getting the same error while installing rPython package.

I followed the workaround code by krshedd and got find_rtools() is TRUE now.

The problem is when I try to install rPython using install("C:/Users/urwa/Downloads/rPython")
and I am back with the same error

WARNING: Rtools is required to build R packages, but no version of Rtools compatible with R 3.5.0 was found. (Only the following incompatible version(s) of Rtools were found:3.5)

Please download and install the appropriate version of Rtools from http://cran.r-project.org/bin/windows/Rtools/.

If you install the development version of devtools, it will work. First, use @aparpara's workaround, then upgrade devtools:

library(devtools)
assignInNamespace("version_info", c(devtools:::version_info, list("3.5" = list(version_min = "3.3.0", version_max = "99.99.99", path = "bin"))), "devtools")
find_rtools() # is TRUE now

devtools::install_github("r-lib/devtools")

[rjrich]

@wch: Thanks for the tip about installing the development version of devtools! This enabled me to install the development version of the "philentropy" package in Windows 10 ver 1709. Thanks also to @aparpara for the initial workaround.

[bshor]

When I tried this I'm getting errors for loading any other package...

Error: package or namespace load failed for ‘haven’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
 there is no package called ‘Rcpp’

How do I reverse this? My R installation is screwed (for now)...

[guilhermefrias23]

Thank you! It worked really well!

[kevinushey]

Any chance that a CRAN release will be coming soon with this fix?

[jimhester]

Yes, a CRAN release will be coming soon, in the next week or two.

[majusus]

@krshedd ..thank you this work around works even for the updated versions of R and Rtools.. (Y)

Any other ways to install gganimate @thomasp85?

[jimhester]

Could you try

pkgbuild::with_build_tools(remotes::install_github("thomasp85/tweenr"))

With the CRAN versions of pkgbuild and remotes

[ankitgupta124]

Hi, facing trouble with rtools 3.5 on R3.5.1 windows.
It shows following message when I use find_rtools()

Error in find_rtools() : could not find function "find_rtools"

Please help.

[plnnr]

@jimhester This worked!

Could you try

pkgbuild::with_build_tools(remotes::install_github("thomasp85/tweenr"))

With the CRAN versions of pkgbuild and remotes

[jamesgriggs]

Hi,

Trying the workaround with R 3.5.1 to get devtools/Rtools to work as described in this issue, but it doesn't appear to work. Any advice?

library(devtools)
assignInNamespace("version_info", c(devtools:::version_info, list("3.5" = list(version_min = "3.3.0", version_max = "99.99.99", path = "bin"))), "devtools")

Error in bindingIsLocked(x, ns) : no binding for "version_info"

find_rtools()

Error in find_rtools() : could not find function "find_rtools"

[jimhester]

@jamesgriggs please just use the CRAN version of devtools, the workaround is no longer necessary.

[anqelnquyenx]

@jimhester I am having trouble with Rtools. I downloaded the latest version and followed steps 1-3 on your site https://www.r-project.org/nosvn/pandoc/devtools.html but I am still getting the message: Error in write.xlsx(simple.list, file = "simple_list.xlsx") :
could not find function "write.xlsx"

Your help is greatly appreciated. Thank you.

[ritwikguhathakurta]

Error in find_rtools() : could not find function "find_rtools"
How to reslove the issue?? Please help..

[isabelle-fischer]

I have the same problem. I am using R version 3.5.1 and RTools 35. I installed the devtools Package and loaded it, but I always get this error message:

Error in find_rtools() : could not find function "find_rtools"

I also tried every suggested workaround (even though they should not be necessary), but nothing works. I'm running out of ideas.

[isabelle-fischer]

Ah, found aother workaround!

Loaded pkgbuild and then ran find_rTools . Worked perfectly fine!

[ritwikguhathakurta]

That works fine with pkgbuild but not with devtools.

find_rtools() was removed from devtools, it is only in pkgbuild now. If you want to call the function you need to load pkgbuild.

[ritwikguhathakurta]

Thank you very much for your response..

I have R3.5.1 and Rtools 3.5.0.4. I tried library(pkgbuild), and find_rtools() is coming TRUE. However when I run "devtools::install_github("rstudio/reticulate", force=TRUE)", I get the error below. Any suggestions are appreciated!

Thank you!! I have been trying to get this done for an hour now, I am new to R and did not understand most of the discussions happening. But this answer was very clear! Thanks a lot.

[a3guyen]

find_rtools() was removed from devtools, it is only in pkgbuild now. If you want to call the function you need to load pkgbuild.

Yeah. Thanks for that. I am new to R but this really help. I use windows 10, R 3.5.2 version so here is what I did:

install.packages("devtools")
library(devtools)
find_rtools() # Error in find_rtools() : could not find function "find_rtools"
install.packages("pkgbuild")
library(pkgbuild)
find_rtools()
[1] TRUE

So basically we need to install pkgbuild instead of devtools to get TRUE result from find_rtools() function
