Data.table: Cannot install data.table under R 3.5.0

[plarson2]

I recently updated to R 3.5.0 and can now no longer install data.table.

What should I do?

install.packages("C:/Users/owner/Downloads/data.table_1.10.4-3.tar.gz", repos = NULL, type = "source")
Installing package into ‘C:/Users/owner/Documents/R/win-library/3.5’
(as ‘lib’ is unspecified)

• installing source package 'data.table' ...
  * パッケージ 'data.table' の解凍および MD5 サムの検証に成功しました
  * libs

* arch - i386
system(cmd) で警告がありました: 'make' not found
ERROR: compilation failed for package 'data.table'

• removing 'C:/Users/owner/Documents/R/win-library/3.5/data.table'
  In R CMD INSTALL
  Warning in install.packages :
  installation of package ‘C:/Users/owner/Downloads/data.table_1.10.4-3.tar.gz’ had non-zero exit status

I second that. data.table does not build under the development version of R either.

I am downgrading to R-3.4.4 for the time being.

[jangorecki]

I had seamless installation of recent data.table and R 3.5.0 built from source on linux. CRAN check logs are not that relevant here because they run 1.10.4-3, so any issues present there might have been resolved already. Are you still have issue installing data.table from sources having Rtools for 3.5.0 installed? You might need to install recent Rtools.

[plarson2]

It appears that Rtools is not available for R 3.5.0

install.packages("Rtools")
Installing package into ‘C:/Users/owner/Documents/R/win-library/3.5’
(as ‘lib’ is unspecified)
Warning in install.packages :
package ‘Rtools’ is not available (for R version 3.5.0)

[jangorecki]

@plarson2 look for Rtools on R-project website, it is not a package.

[plarson2]

Thanks. I installed the latest Rtools but nothing has changed. I still cannot install data.table.

[facorread]

Same experience here. That is why I downgraded.

[plarson2]

Hopefully it will get resolved soon.

[jangorecki]

@plarson2 did you try to install from source? on windows install.packages will attempt to install from binaries, even when having Rtools installed.

[plarson2]

From the .tar ? Yes, tried that.

[pierrot07]

same problem, just solved now!
1/ download and install Rtools 3.5.0; don't forget to check the modify PATH option
2/ in R type install.packages("data.table")
3/ you get the message: ..._Package which is only available in source form, and may need
compilation of C/C++/Fortran: ‘data.table’_
4/ then a small window opens, asking you if you want to install from source: click YES
5/ data table is installed from source ..._data.table_1.10.4-3.tar.gz_

now you can load Rcmdr and it works
I hope it will work with you!!!!

In addition to above, I had to manually remove an old RBuildTools directory
from the PATH file , and then reinstall RTools35 into the c:\\RTools directory.
Now everything is working for me.

I've added to the stackoverflow issue

[JoeFernando]

Had the same problem. I'm on a Windows 10 machine. This is how I solved it:

• uninstall rtools via "Add/Remove Programs"
• remove devtools from your library - remove.packages("data.table")
• Go to environmental variables and remove all rtools paths (see point 5 in link https://www.biostat.wisc.edu/~kbroman/Rintro/Rwinpack.html) / you need to remove from both "user variables" and "System variables" - I had rtools path in both.
• download the latest rtools and install
• In the installation selection menu check the "PATH" - super important
• once done, go back to environmental variables and check if you can see rtools
• then in r remove.packages("data.table")
• library(devtools)
• install_github("Rdatatable/data.table", build_vignettes=FALSE)
  You should be good to go.....

[jangorecki]

@JoeFernando if you are building from source you don't need to use devtools::install_github, use

install.packages("data.table", repos="https://Rdatatable.github.io/data.table")

instead.
When you use install_github you always install latest master, when you use our repo you install latest master that passed R CMD check. Unless you are developing data.table the latter should be preferred.

@plarson2 could you try Joe procedure? if it works for you please close this issue.

But @jangorecki this problem is on Windows, where we already have pre-compiled binaries which are much easier. Go straight to suggesting the AppVeyor compiled and tested binary, like I did here :

https://stackoverflow.com/a/50031325/403310

I linked to the tweet there, and included the graphic. See the comments to the answer: Windows users who have upgraded to R 3.5 need to click the R_VERSION=r_devel one and not the the R_VERSION=r_release one. Until AppVeyor updates to R 3.5, and then it won't matter which one they click.

[jangorecki]

@mattdowle I was not aware that R-devel binaries will work on R 3.5. Good to know

[HughParsonage]

They 'work' but emit a warning that they were built under a different version, so will fail R CMD check for example.

[plarson2]

@JoeFernando THANK YOU. Works!

[jangorecki]

1.11.0 binaries are available on CRAN already.

[aadler]

Some of us on Windows still prefer to build from source to take advantage of machine-specific optimizations.
