我已经安装了 ruby 和 Rails 一段时间并参与了一些项目。最近，我安装了 Xcode 5 开发者预览版，以便让我的应用程序为 iOS 7 做好准备。我只是提一下这一点，以防新的 Xcode 搞砸了。
我第一次注意到这个错误是在尝试时
rake asets:precompile
在rails项目目录中。它给出以下错误:
/Users/User/.rvm/bin/ruby:第 6 行:/Users/User/.rvm/bin/ruby:参数列表太长 /Users/User/.rvm/bin/ruby:第 6 行:/Users/User/.rvm/bin/ruby:未定义错误:0
当我尝试时:
ruby -v
终端窗口一开始没有任何响应，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
当我尝试时
rvm get stable
我得到:

最后，当我输入时:
rvm install ruby-2.0.0-p247
我得到:

但还是和以前一样。
据我所知，我没有对系统进行任何更改，我只安装了新的 Xcode。有人知道这里出了什么问题吗？不幸的是，这些 rvm/ruby/终端命令，或者更准确地说，这个 ruby install path-permission-rights 对我来说仍然很新。非常感谢您的宝贵时间!
最佳答案
确保您的 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 - 并按照说明进行操作
要使 ruby 在下一个 shell session 中持续使用，请使用:
rvm use --default ruby
它将创建default别名，该别名在rvm启动时加载
