我在安装R软件包PearsonDS时遇到问题。在RStudio中，我运行：
> install.packages("PearsonDS")
Warning in install.packages :

因此，我从https://cloud.r-project.org/src/contrib/下载了程序包，然后打开PearsonDS_1.1.tar文件，然后在终端的PearsonDS文件夹中输入并运行R CMD INSTALL .。 config.log中的错误如下：

我该如何解决？我寻找了类似的错误（例如https://trac.macports.org/ticket/54506?cversion=0&cnum_hist=2），但未能解决问题。
