Error in compileCode & invalid connection

Short summary of the problem
When I run the following code:
fit = stan(“normal_mean.stan”,data=stan_data,chains = 1,iter=10^4)
I obtain the following error message:

Error in compileCode(f, code, language = language, verbose = verbose) :
from C:/Users/Willem/Documents/R/win-library/3.6/StanHeaders/include/src/stan/model/model_header.hpp:4, from file1e7c7c9b298e.cpp:14:C:/Users/Willem/Documents/R/win-library/3.6/StanHeaders/include/stan/math/rev/core/set_zero_all_adjoints.hpp:14:13: warning: ‘void stan::math::set_zero_all_adjoints()’ defined but not used [-Wunused-function] static void set_zero_all_adjoints() { ^make: *** [C:/PROGRA~1/R/R-36~1.3/etc/x64/Makeconf:215: file1e7c7c9b298e.o] Error 1
In addition: Warning message:
In system(paste(CXX, ARGS), ignore.stdout = TRUE, ignore.stderr = TRUE) :
‘-E’ not found
Error in sink(type = “output”) : invalid connection

I use Windows 10 and for as far as I know, I have installed all the required packages and Rtools.

I can’t find out what the problem is and all the given solutions seem not to work for me unfortunately. Thank you in advance for your reaction.

I think I have a similar problem. I ran the following code:
fit<- stan(file=‘EU.stan’,
data=list(N=N,nsubj=nsubj,subjs=subjs,choices=choices,x1a=x1a,x2a=x2a,x3a=x3a,x4a=x4a,
x1b=x1b,x2b=x2b,x3b=x3b,x4b=x4b,p1a=p1a,p2a=p2a,p3a=p3a,p4a=p4a,p1b=p1b,p2b=p2b,p3b=p3b,p4b=p4b,sid=sid),
warmup=5,
chains=4,
iter=100,
init_r=1,
verbose=FALSE)

I then got the following error:
Error in compileCode(f, code, language = language, verbose = verbose) :

Can someone please advise. Thanks in advance!

We’re having some compatibility issues with R4.2 and the CRAN rstan, can I get you to restart your R session and then install the preview of the next rstan version using:

remove.packages(c("rstan","StanHeaders"))
install.packages("StanHeaders", repos = c("https://mc-stan.org/r-packages/", getOption("repos")))
install.packages("rstan", repos = c("https://mc-stan.org/r-packages/", getOption("repos")))

Thank you! Looks like it is working now.
