使用 R 3.6.0 编译 stan 文件时出错。和赢10

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

In addition: Warning message:

Error in sink(type = "output") : invalid connection

一些非英语页面说我们可以通过执行以下 R 脚本来克服，但它在我的情况下不起作用：

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)

上面的 R 脚本与以下页面中的相同：

我尝试按照以下页面卸载并安装，但出现上述错误。

对我来说，通过手动将以下行添加到文件 .R/Makevars.win 中解决了该问题。

CXX14 = "C:\Rtools\mingw_64\bin\g++.exe"
