安装 OSX 10.8.5 后，我开始出现一些错误，在仔细阅读 stackoverflow 中不同的帖子后，我没有找到正确的答案。我将非常感谢您的帮助

当我尝试安装 libyaml 时，我有一些警告

$ sudo rvm pkg install libyaml 

Beware, 'rvm pkg ...' is deprecated, read about the new autolibs feature: 'rvm help autolibs'.

首先，永远不要sudo rvm将 sudo 与 rvm 一起使用会导致您想要避免的各种文件权限问题。

更多信息在这里：http ://rvm.io/rubies/rubygems

如果您一直在使用sudo gem install ..，您可以通过运行来修复您的 rvm 权限

sudo chown -R $USER: ~/.rvm

无论如何，要安装 libyaml，您应该使用自制软件。看起来你需要安装 libyaml 然后重新安装你的 Ruby。尝试：

$ brew install libyaml
$ rvm reinstall 2.0.0

编辑：

根据您上面的代码，您似乎对自制软件有一些问题。尝试运行

$ brew doctor
$ rvm install ruby-2.0.0-p247

如果这些运行完成，那么您可以再次尝试 libyaml。

$ brew install libyaml

如果这些仍然返回该bad interpreter: no such file or directory错误，请尝试修复它。

使用 brew 时出现“错误的解释器”错误

/usr/local/lib/ruby/2.0.0/不是 RVM Ruby - 你需要说rvm使用已安装的 ruby​​：

rvm list

它将显示如下内容：

   ruby-1.9.3-p448 [ x86_64 ]
   ruby-2.0.0-p247 [ x86_64 ]

你可以说 rvm 来使用 2.0.0 ruby​​：

rvm use 2.0.0-p247

另一个答案也是正确的-永远不要使用sudo
