小牛的系统红宝石和宝石破碎 [英] Mavericks system Ruby and gem broken

问题描述

当我尝试运行ruby -v或gem -v(或任何其他命令)时，我得到:

When I tried to run ruby -v or gem -v (or any other command), I get:

dyld: lazy symbol binding failed: Symbol not found: _ruby_run
  Referenced from: /usr/local/bin/ruby
  Expected in: /usr/lib/libruby.dylib

dyld: Symbol not found: _ruby_run
  Referenced from: /usr/local/bin/ruby
  Expected in: /usr/lib/libruby.dylib

这是在我运行rvm system以暂时切换到系统默认Ruby之后的. RVM工作正常，但是我特别需要在系统Ruby上安装gem，因此不能这样做.

This is after I ran rvm system to temporally switch to the system default Ruby. RVM is working fine, but I have a special need to install a gem to the system Ruby and I can't because of this problem.

有人知道为什么吗?似乎是到Ruby的某种链接问题，但我不知道该如何解决.

Does anyone know why? It seems to be some kind of link problem to Ruby, but I'm don't know how to solve this.

我运行了which ruby，它现在位于"/usr/local/bin/ruby​​"中.

I ran which ruby and it's at this point located in "/usr/local/bin/ruby".

我在"/usr/lib/"中检查了Ruby，它指向我的系统Ruby:"../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/lib/ruby​​"

I checked the Ruby in "/usr/lib/" and it's pointing to my system Ruby: "../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/lib/ruby"

任何帮助将不胜感激.

推荐答案

这对我有用.我将libruby的符号链接更改回lib ruby​​.1.8.6.dylib

This worked for me. I changed the symbolic link for libruby back to lib ruby.1.8.6.dylib

$ sudo cp -p /usr/local/lib/libruby.1.8.6.dylib /usr/lib
$ cd /usr/lib
$ sudo rm libruby.dylib
$ sudo ln -s libruby.1.8.6.dylib libruby.dylib

如果您需要返回到Ruby 2.0

If you need to go back to Ruby 2.0

$ sudo rm libruby.dylib
$ sudo ln -s libruby.2.0.0.dylib libruby.dylib
