Question using cmdstanr

Interfaces

Short summary of the problem

I have checked some topics and try to use cmdstanr to install cmdstan

install_cmdstan(cores = 4, check_toolchain = FALSE, overwrite=TRUE)

And it returns,

  • Latest CmdStan release is v2.27.0
  • Installing CmdStan v2.27.0 in C:/Users/SF Liu/Documents/.cmdstanr/cmdstan-2.27.0
  • Downloading cmdstan-2.27.0.tar.gz from GitHub…
  • Removing the existing installation of CmdStan…
  • Download complete
  • Unpacking archive…
  • Building CmdStan binaries…
    Error in rethrow_call(c_processx_exec, command, c(command, args), pty, :
    Command ‘mingw32-make.exe’ not found @win/processx.c:982 (processx_exec)
    Type .Last.error.trace to see where the error occurred
    In addition: Warning messages:
    1: In readChar(make_local_path, file.info(make_local_path)$size) :
    can only read in bytes in a non-UTF-8 MBCS locale
    2: In readChar(make_local_path, file.info(make_local_path)$size) :
    can only read in bytes in a non-UTF-8 MBCS locale

My system has installed make.exe but doesn’t get mingw32-make.exe. I’m wondering how to fix it.

I believe the answer is here: Cmdstanr with Rtools 4.0 on Windows 10: mingw32-make.exe missing? - #7 by rok_cesnovar

but it should be featured more prominently somewhere in the CmdStanR vignettes - perhaps a “troubleshooting the installation” section?

this has also been a pain point for CmdStanPy users on Windows - we’re working on a better solution that doesn’t require following instructions and checking screenshots.

@mitzimorris This was the answer in the past. Well it still is, but we handle this automatically also. We install mingw32-make and fix and PATH issues or warn on other problematic issues that we cant fix automatically.

@sf-Liu you note that you ran:

install_cmdstan(cores = 4, check_toolchain = FALSE, overwrite=TRUE)

Please set the check_toolchain to TRUE or just remove the argument (its on by default).

Thanks. I tried to write
pacman -Syu mingw-w64-x86_64-make
in Rtools Bash, but got
(9/9) Checking the key in the key ring [#####################] 100%

mingw-w64-x86_64-make: /mingw64 already exists in the file system
An error has occurred and no software packages have been updated.

I may meet some odd problems.

The reason I add ‘check_toolchain = FALSE’ is just because I can not run it with True. It returns

install_cmdstan(cores =4, overwrite=TRUE)
Error:
RTools installation found but PATH was not properly set.
Run check_cmdstan_toolchain(fix = TRUE) to fix the issue.

OK, let’s try the suggestion.

check_cmdstan_toolchain(fix = TRUE)
Installing mingw32-make and writing RTools path to ~/.Renviron …
Error in rethrow_call(c_processx_exec, command, c(command, args), pty, :
Command ‘pacman’ not found @win/processx.c:982 (processx_exec)
Type .Last.error.trace to see where the error occurred
In addition: Warning message:
No write permissions in the RTools folder. This might prevent installing mingw32-make. Consider changing permissions or reinstalling RTools in a different folder.

Here is the path of my Rtools 4.0,
D:\R\Rtools
And the PATH environment I set is
D:\R\Rtools\mingw_64\bin
Should I put it in C:/ or rename it? Or can you see anything goes wrong?

I reinstalled the Rtools in C:\ and then I can run the cmdrstan. I guess it fixed! Thanks.
