I was trying to install cmdstan via Rstudio on Win10 OS. CmdStanR was successfully installed. I also followed https://www.maxmantei.com/2020/05/16/cmdstanr-windows/ to solve the problem of error message telling me that mingw32-make could not be found. However, I still got error when installing cmdstan using install_cmdstan(cores = 2, overwrite=TRUE). Here is the error message, could you please help? Note that my Rtool is indeed installed in C:/Program Files (x86)/rtools40 and I have add path for folders C:/Program Files (x86)/rtools40\usr\bin and C:/Program Files (x86)/rtools40\mingw64\bin

kind of suspecting this path with Program Files (x86), seems it could not recognize a path with space? but this is the default Rtool installation path.
I don’t have Windows, but I think you are probably be right about the space in the path being an issue. But I thought the default installation path was C:\rtools40, like in the image of the installation window on the Rtools page:
If it’s possible to install it there then that might fix the problem but @rok_cesnovar will know better than I do and may have other ideas.
I just reinstalled rtool 4.0, reinstalled cmdstanr, reboot OS. mingw32-make issue is gone but still get the following error
...failed updating 1 target...
...skipped 1 target...
...updated 46 targets...

I tried the examples in https://mc-stan.org/cmdstanr/articles/cmdstanr.html and it worked without any error. For the moment, I’m going to stay with the current set-up. No idea of these Windows compilers things, also got a lot of problems previously when installing Docker and so on. Maybe one day I will get some errors with a certain model then we will see. or I can get a Mac eventually haha :)
