在装arulesViz时提示seriation安装失败，R3.6.3， 要如何处理？

  • installing source package ‘seriation’ ...
    • package ‘seriation’ successfully unpacked and MD5 sums checked
    • using staged installation
    • libs

    Warning in install.packages :

The downloaded source packages are in
‘/private/var/folders/sy/bwwry6550nz44hj9s_55cz200000gn/T/RtmpJ9CAZ7/downloaded_packages’

可能是缺少C++ library 提供的放头文件。安装C++或者Xcode Command Line Tools。

xcode-select --install
