Rimozione di HomeBrew? [duplicare]

1

Ho dovuto ricostruire il sistema operativo per il mio sistema iMac / Yosemite. Homebrew persiste nell'installazione del software nel vecchio profilo corrotto. Cosa dovrei fare? Penso che dovrei rimuovere Homebrew e reinstallarlo, ma ho davvero paura di rovinare. Si prega di aiutare con un consiglio di base, solido, infallibile.

Questo è lo script di disinstallazione di Homebrew ufficiale, dal link :

require "optparse"

# Default options
options = {
  :force => false,
  :quiet => false,
  :dry_run => false,
  :skip_cache_and_logs => false,
}

# global status to indicate whether there is anything wrong.
$failed = false

module Tty extend self
  def blue; bold 34; end
  def white; bold 39; end
  def red; underline 31; end
  def reset; escape 0; end
  def bold n; escape "1;#{n}" end
  def underline n; escape "4;#{n}" end
  def escape n; "3[#{n}m" if STDOUT.tty? end
end

class Array
  def shell_s
    cp = dup
    first = cp.shift
    cp.map{ |arg| arg.gsub " ", "\ " }.unshift(first) * " "
  end
end

class Pathname
  def resolved_path
    self.symlink? ? dirname+readlink : self
  end

  def /(other)
    self + other.to_s
  end

    if self.symlink?
      puts to_s + " -> " + resolved_path.to_s
    elsif self.directory?
      puts to_s + "/"
    else
      puts to_s
    end
  end
end

  puts "#{Tty.blue}==>#{Tty.white} #{args.shell_s}#{Tty.reset}"
