Ruby / Brew 停止工作优胜美地

Question

我对此很陌生，所以请和我一起玩..

我已经为这个问题寻找了一个星期的解决方案。

Ruby 似乎无法正常工作

ruby
-bash: ruby: command not found

或

ruby -v
-bash: ruby: command not found

每当我尝试自制软件时，都会回来

/usr/local/bin/brew: /usr/local/Library/brew.rb:     /System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby: bad     interpreter: No such file or directory
/usr/local/bin/brew: line 21: /usr/local/Library/brew.rb: Undefined error: 0

正如您在上面看到的，我已按照其他人的建议将 ruby​​ 框架从 1.8 更改为 Current，但这并没有像遇到相同问题的用户那样解决问题。

所以搜索继续……

我的 usr/local/bin/brew 脚本看起来像这样 -

#!/System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby -W0
# encoding: UTF-8

std_trap = trap("INT") { exit! 130 } # no backtrace thanks

HOMEBREW_BREW_FILE = ENV['HOMEBREW_BREW_FILE']

if ARGV == %w{--prefix}
  puts File.dirname(File.dirname(HOMEBREW_BREW_FILE))
  exit 0
end

require 'pathname'
HOMEBREW_LIBRARY_PATH =     Pathname.new(__FILE__).realpath.dirname.parent.join("Library/Homebrew").to_s
$:.unshift(HOMEBREW_LIBRARY_PATH + '/vendor')
$:.unshift(HOMEBREW_LIBRARY_PATH)

case ARGV.first when '-h', '--help', '--usage', '-?', 'help', nil
  require 'cmd/help'

  exit ARGV.first ? 0 : 1

  puts HOMEBREW_VERSION
  exit 0
when '-v'
  puts "Homebrew #{HOMEBREW_VERSION}"
  # Shift the -v to the end of the parameter list
  ARGV << ARGV.shift
  # If no other arguments, just quit here.
  exit 0 if ARGV.length == 1
end

   # Check for bad xcode-select before anything else, because `doctor` and
# many other things will hang
# Note that this bug was fixed in 10.9
if OS.mac? && `xcode-select -print-path 2>/dev/null`.chomp == '/' &&     MacOS.version < :mavericks
  ofail <<-EOS.undent
  Your xcode-select path is currently set to '/'.
  This causes the `xcrun` tool to hang, and can render Homebrew unusable.
  If you are using Xcode, you should:
    sudo xcode-select -switch /Applications/Xcode.app
  Otherwise, you should:
    sudo rm -rf /usr/share/xcode-select

  exit 1
end

case HOMEBREW_PREFIX.to_s when '/', '/usr'
  # it may work, but I only see pain this route and don't want to support it
  abort "Cowardly refusing to continue at this prefix: #{HOMEBREW_PREFIX}"

这是否有意义或敲响了警钟？ 这可能与我收到 Homebrew 或 Ruby 错误的原因有关吗？

任何帮助将不胜感激。

我很乐意为我们提供尽可能多的信息来解决这个问题！ :)

编辑：

这是我尝试运行 brew doctor 时发生的情况：

如果您无法在终端提示符下运行echo "puts 'hello world'" | /System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby，则说明您的系统 Ruby 已卸载，您应该重新安装 OS X 以恢复它。
