Thanks @andrjohns, there is now other errors and the model finish running.
Hi Andrew! :)
How are you? How are things in Aussie?
I am pretty new to R and have hardly any experience with coding.
I wanted to run a brm model through the package “brms” it uses Stan. I got the same message like Chris at first. Then I copy pasted everything code you suggested and also created the folder with markevars.win (I created a text file, or what sort of file is this meant to be?)
and after running > cat(“CXX14FLAGS += -O3 -mmmx -msse -msse2 -msse3 -mssse3 -msse4.1 -msse4.2”,file = “~/.R/Makevars.win”, sep = “\n”, append = FALSE)
library(rstan)
example(stan_model,run.dontrun=TRUE,verbose=TRUE)
I get
Error in cleanup_makevar(old) :
argument “RMU” is missing, with no default
In addition: Warning messages:
1: In find.package(package, lib.loc, verbose = verbose) :
package ‘base’ found more than once, using the first from
“C:/PROGRA~1/R/R-40~1.4/library/base”,
“C:/Program Files/R/R-4.0.4/library/base”
2: In system(paste(CXX, ARGS), ignore.stdout = TRUE, ignore.stderr = TRUE) :

would you be able to help here, please?
best wishes,
Adele
This error occurs when your withr package is at a version greater than 2.2.0. You just need to downgrade your package using:
devtools::install_version("withr", version="2.2.0")
Then make sure not to update. It’s a bit annoying but will be fixed in the next release
Hey andrjohns,
I have a very similar problem and can’t solve it.
Executing
example(stan_model, run.dontrun = TRUE, verbose=TRUE)
returns
Error in prep_call_sampler(object) : could not find function "prep_call_sampler" In addition: Warning messages: 1: In find.package(package, lib.loc, verbose = verbose) : package ‘base’ found more than once, using the first from “C:/PROGRA~1/R/R-40~1.4/library/base”, “C:/Program Files/R/R-4.0.4/library/base” 2: In system(paste(CXX, ARGS), ignore.stdout = TRUE, ignore.stderr = TRUE) : '-E' not found
So what is happening here? I tried installing rstan on different ways (with install.rstan and from source), doublechecked those installations, removed them and reinstalled them, with and without loading library.
devtools::install_version("withr", version="2.2.0")
returns
Error in loadNamespace(name) : there is no package called ‘devtools’
What can I do to finally get Stan working?
Btw: there is no .R folder in my documents and I cannot create one of such name as Windows prohibits the dot in folder names. I also tried adding the makevars file in /Documents/R/ but did not quite grasp of what type this file should be. Creating a .txt and just naming it Makevars.win was not the solution.
I need a bit more information about your system. Can you post the outputs from:
Sys.getenv("BINPREF")
Sys.getenv("PATH")
readLines("~/.R/Makevars.win")
readLines("~/.Renviron")
readLines("~/.Rprofile")
Output is:

It looks like you haven’t completed the Getting Started instructions in the RStan wiki to prepare your system.
Can you complete the Instructions for Windows and then install RStan from source via:
# Compile packages using all cores
Sys.setenv(MAKEFLAGS = paste0("-j",parallel::detectCores()))
install.packages(c("StanHeaders","rstan"),type="source")
I followed complete instructions and ignored that I didn’t get the error messages that the link you provided suggested would make the following steps necessary. Sys.which("make") also seems to work yet executing install.packages("jsonlite", type="source") sends me on an endless cycle of a warning asking me to resart R prior to installation. I negated that to break the circle. I executed library("rstan") and library(rstan) just to be sure which didn’t produce an error.
I executed example(stan_model, package = "rstan", run.dontrun = TRUE)
and return was
Error in prep_call_sampler(object) :
could not find function “prep_call_sampler”
In addition: Warning message:
In system(paste(CXX, ARGS), ignore.stdout = TRUE, ignore.stderr = TRUE) :
‘C:/rtools40/usr/mingw_/bin/g++’ not found
Let’s debug the jsonlite install first, since we need to make sure that your RTools installation is accessible from R.
In a clean R session (with RStan not loaded) can you try to remove any existing RStan install via
remove.packages("rstan")
if (file.exists(".RData")) file.remove(".RData")
Then, restart R and try the jsonlite install again
I executed the code and reinstalled jsonlite via "install.packages("jsonlite", type = "source"). But now what?
Great, if that reinstalled without issue, then things are looking good. Next, can you try the rstan source install again:
# Compile packages using all cores
Sys.setenv(MAKEFLAGS = paste0("-j",parallel::detectCores()))
install.packages(c("StanHeaders","rstan"),type="source")
Executing the model again returns
Error in prep_call_sampler(object) :
could not find function “prep_call_sampler”
In addition: Warning message:
In system(paste(CXX, ARGS), ignore.stdout = TRUE, ignore.stderr = TRUE) :
‘C:/rtools40/usr/mingw_/bin/g++’ not found
Executing the model after library(rstan) commands returns
Error in prep_call_sampler(object) :

In addition: Warning messages:
1: In find.package(package, lib.loc, verbose = verbose) :

D -- DLL MD5 mismatch, broken installation.I can’t see anything obviously wrong there, let’s try a basic model to see if that will work.
First you’ll need to downgrade your withr package or you’ll run into issues:
devtools::install_version("withr",version="2.2.0")
Next, restart R and then run:
modcode = "data{real y_mean;} parameters{real y;} model{y~normal(y_mean,1);}"
library(rstan)
rstan_options(auto_write=FALSE)
stan(model_code=modcode,data=list(y_mean=0))
Does that error?
It does show a warning
> stan(model_code=modcode,data=list(y_mean=0))

That means that your installation is completely setup and working fine. Is it one of your models that is giving the prep_sampler error or just the example model?
Hi Andrew!
Thank you so much for your help especially considering it was the weekend!
I tried it. then I got another warning message:
Error in cleanup_makevar(old) :
argument “RMU” is missing, with no default
I looked it up and someone suggested this:
file.rename(“~/.R/Makevars.win”, “~/.R/Makevars.win.bak”)
Now its working! YAYY!! Thank you!! :)
Hey @andrjohns just came back to tell you how thankful I am for you taking the time to help me. I really appreciate it. Had some serious deadline to meet at the time. You helped a lot to get things done. Thanks and keep up the good work.
