RVM ruby安装问题
我已经安装了ruby和rails一段时间并且在一些项目上工作。 最近我安装了Xcode 5开发人员预览版，以便为iOS 7准备好我的应用程序。我只是提到这个，以防新Xcode搞砸了。
我第一次注意到这个错误
rake asets:precompile 在rails项目目录中。 它给出以下错误：
/Users/User/.rvm/bin/ruby:line 6：/Users/User/.rvm/bin/ruby：参数列表太长/Users/User/.rvm/bin/ruby:line 6：/ Users / User /.rvm/bin/ruby：未定义的错误：0
当我尝试：
ruby -v
终端窗口首先没有响应，终端标题在“bash”和“env”之间闪烁，但随后显示以下错误：
/Users/User/.rvm/bin/ruby: line 6: /Users/User/.rvm/bin/ruby: Argument list too long /Users/User/.rvm/bin/ruby: line 6: /Users/User/.rvm/bin/ruby: Undefined error: 0
当我尝试
rvm get stable
我明白了：

最后，当我进入：
rvm install ruby-2.0.0-p247
我明白了：

但它仍然和以前一样。
据我所知，我没有改变任何系统，我只安装了新的Xcode。 有人知道这里有什么不对吗？ 不幸的是，这些rvm / ruby / terminal命令，或者更确切地说，这个ruby如何安装路径权限权限对我来说仍然是一个新手。 非常感谢您的宝贵时间！
确保你的rvm是最新的：
rvm get stable
然后你需要运行：
rvm use ruby
这将确保您的环境设置正确，如果出现问题，它会显示警告，您需要始终阅读警告 – 并按照说明操作
使用ruby持久化下一个shell会话使用：
rvm use --default ruby
它将创建在启动rvm时加载的default别名
看起来gem路径中发生错误。 你确定@global gemset存在吗？ 运行以下内容应该可以解决问题。
rvm gemset create global
