Updating, path and makefile

Interfaces
1

I am a statistics student, not a software developer, using cmdstanr on Windows. I reinstalled it to get version 2.31.

I have the message
“NOTE: Please add C:/Users/Admin/.cmdstan/cmdstan-2.31.0/stan/lib/stan_math/lib/tbb to your PATH variable.
You may call
mingw32-make install-tbb
to automatically update your user configuration.
— CmdStan v2.31.0 built —”

Could someone please explain this? What is a path variable, and how does one update it? What does it mean to call mingw32-make install-tbb, and how does one do it?

I have tried the R command

 set_cmdstan_path(path = 'C:/Users/Admin/.cmdstan/cmdstan-2.31.0/stan/lib/stan_math/lib/tbb')

but I get the response
“CmdStan path set to: C:/Users/Admin/.cmdstan/cmdstan-2.31.0/stan/lib/stan_math/lib/tbb
Warning message:
Can’t find CmdStan makefile to detect version number. Path may not point to valid installation.”

That message is displayed as part of the cmdstan setup process, you can safely ignore this as it is handled by cmdstanr

Fantastic, thanks Andrew.
