Error on the stan file compilation using R 3.6.0. and Win 10

问题

Error in compileCode(f, code, language = language, verbose = verbose) : 
  Compilation ERROR, function(s)/method(s) not created! Error in .shlib_internal(commandArgs(TRUE)) : 
  C++14 standard requested but CXX14 is not defined
Calls: <Anonymous> -> .shlib_internal
Execution halted
In addition: Warning message:
In system(cmd, intern = !verbose) :
  running command 'C:/PROGRA~1/R/R-36~1.0/bin/x64/R CMD SHLIB file1a1860a0379.cpp 2> file1a1860a0379.cpp.err.txt' had status 1
Error in sink(type = "output") : invalid connection

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.

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"
