在R中安装软件包时出错

Question

我试图通过R Studio在R中安装软件包，但出现以下错误：

installing the source package ‘bizdays’

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

Warning in install.packages :
  installation of package ‘bizdays’ had non-zero exit status

The downloaded source packages are in
    ‘/private/var/folders/z9/vfdjnsxx5zv15kdvfdy65trh0000gn/T/RtmpvkSXSt/downloaded_packages’

我正在使用Mac OS。有人知道如何解决这个问题吗？
