Apologies in advance if this post is a bit vague.
We’re trying to install CmdstanR on a machine with more RAM/computing power than I currently have, but I don’t own the machine and have been assisting with remote access.
First, after installing the R package cmdstanr, we run
check_cmdstan_toolchain which yields:
Error: Rtools43 installation found but the toolchain was not installed. Run cmdstanr::check_cmdstan_toolchain(fix = TRUE) to fix the issue.
Then, we run that (with
fix = TRUE) and it yields:
Installing mingw32-make and g++ with Rtools43 Error: Installation of the toolchain failed. Try reinstalling RTools and trying again. If the issue persists, open a bug report at https://github.com/stan-dev/cmdstanr.
So we go in the Windows installation settings, uninstall Rtools43, and install it again. The issue unfortunately persists.
Following a thread on this forum, we tried to add the argument
overwrite = TRUE to
install_cmdstan() which also doesn’t work.
Are these issues common and if so, are there some solutions we can try? Please let me know if I should try some things and report back!
