【问题描述】：

我按照R Compiler Tools for Rcpp on macOS (for R 3.6.x) 中的步骤进行操作，但是当我尝试安装RcppArmadillo 时出现错误。我没有安装 Xcode.app，而是更喜欢使用命令行工具。

here 发布的答案没有帮助:(

【参考方案1】：

this answer 中提到的一个旁注救了我。诀窍是将以下行添加到$(R RHOME)/etc/Makeconf

CPPFLAGS = -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -I/usr/local/include
