我正在尝试为课程安装包 rugarch。
我正在使用 MacOS Mojave 10.14.6 (18G3020)。
我正在使用 RStudio：R 版本 3.5.1 (2018-07-02) -- "Feather Spray" 版权所有 (C) 2018 The R Foundation for Statistical Computing
平台：x86_64-apple-darwin15.6.0（64位）
我搜索的大多数论坛都报告了对 Xquartz 的需求，但我已经安装了它。我也搜索了 https://thecoatlessprofessor.com/programming/cpp/r-compiler-tools-for-rcpp-on-macos-before-r-3.6.0/
想知道接下来要尝试什么。我认为问题与我的文件路径有关，这可能是由于安装 clang4 和 clang6 而造成的？......下面的错误消息涉及编译器问题：'make: *** [RcppArmadillo. o] 错误 127'。谢谢你的帮助！
