我试图在ruby和rvm下安装nokogiri 1.6.1,但失败,错误如下:

最佳答案

检查您的grep版本并通过brew安装最新版本:

$ grep --version
grep (BSD grep) 2.5.1-FreeBSD

$ brew install grep --default-names

# If above fails, you probably need to tap
$ brew tap homebrew/dupes
$ brew install grep --default-names

$ grep --version
grep (GNU grep) 2.14.56-1e3d

“最新版本的osx附带bsd grep,而老版本附带gnu grep。而且,您的构建脚本可能需要gnu grep”
从Maverick的评论中偷来的,复制到这里作为答案,而不是评论,因为我现在已经遇到这个问题好几次了,我很想挽救别人的头痛。= X
