安装ggplot2失败。百度后发现需要先安装rlang包，结果如下，如何解决？

> install.packages("rlang")

Package which is only available in source form, and may need

compilation of C/C++/Fortran: ‘rlang’

These will not be installed

看一下是否有如下报错信息

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

ERROR: compilation failed for package ‘rlang’

mac系统下需要安装xcrun的编译环境
