Rcpp 无法在 Mac OS Monterey, R 4.1.2. 上编译，clang 错误

Question

尝试使用 Intel 计算机让 Rcpp 在 Mac OS Monterey 上的 R 4.1.2 上工作。

> library(Rcpp)
> evalCpp("2 + 2")

我已遵循 Coatless 教授的指示：

https://thecoatlessprofessor.com/programming/cpp/r-compiler-tools-for-rcpp-on-macos/

我相信 Xcode 命令行工具和 gfortran 已安装：

$which gcc 
/usr/bin/gcc

$which gfortran 
/usr/local/bin/gfortran

我已经删除了 ~/.R/Makevars 和 ~/.Renviron。

如有任何帮助，我们将不胜感激 - 非常感谢！

Answer 1

存在对 clang 编译器先前版本的旧引用。

在R中，请输入：

unlink("~/.R/Makevars")
unlink("~/.Renviron")

请重新启动 R，然后尝试：

Rcpp::evalCpp("1+1")
