gcc-8:找不到命令(在安装randomForest时)

Question

我试图在R3.6.3上安装"randomForest“，如下所示：

urlPackage <- "https://cran.r-project.org/src/contrib/Archive/randomForest/randomForest_4.6-14.tar.gz"
install.packages(urlPackage, repos=NULL, type="source")

(install.packages( 'randomForest‘)抛出错误:包’randomForest‘不可用(用于RVersion3.6.3)

然而，上面的行给出了以下错误：

    trying URL 'https://cran.r-project.org/src/contrib/Archive/randomForest/randomForest_4.6-14.tar.gz'

有人知道怎么解决这个问题吗？我在macOS Catalina (Ver10.15.7)

您应该安装gcc8工具：

sudo port install gcc8
