【问题描述】：
我正在尝试安装 OPAM，最终目标是安装 OCAML。我试着跑了
brew install OPAM
我得到了这个错误：
/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- mach (LoadError)
from /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'

from /usr/local/Library/brew.rb:15:in `<main>'
然后我尝试更新 brew
brew update
得到了这个
usage: install [-bCcpSsv] [-B suffix] [-f flags] [-g group] [-m mode]
[-o owner] file1 file2
install [-bCcpSsv] [-B suffix] [-f flags] [-g group] [-m mode]
[-o owner] file1 ... fileN directory
install -d [-v] [-g group] [-m mode] [-o owner] directory ...
似乎我对 brew 所做的任何事情都会给我带来问题。红宝石似乎有问题。
如果我愿意
ruby -v
我明白了
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14]
感谢您的帮助
PS 我尝试在这些上运行 sudo 并得到相同的错误
