Some non-English page said that we can overcome by executing the following R script, but it did not work in my case:
dotR <- file.path(Sys.getenv("HOME"), ".R")
if (!file.exists(dotR))
dir.create(dotR)
M <- file.path(dotR, "Makevars")
if (!file.exists(M))
file.create(M)
cat("\nCXX14FLAGS=-O3 -Wno-unused-variable -Wno-unused-function",
"CXX14 = g++ -std=c++1y",
file = M, sep = "\n", append = TRUE)
The above R script is same as in the following page:

I tried to uninstall and install according to the following page, but the above error occurred.
Rstan installation: https://github.com/stan-dev/rstan/wiki/RStan-Getting-Started
For me, the issue has been solved by adding manually the following line into the file .R/Makevars.win.
CXX14 = "C:\Rtools\mingw_64\bin\g++.exe"
