Cloud Foundry - 在 Ruby 1.9.3 上使用较旧的 VMC - 错误："Can't convert hash into string"

Question

我最近在Win7 PC上安装了Ruby 1.9.3。然后我安装了最新版本的VMC，它似乎运行得很好。然而，有人建议我卸载那个版本，因为它在我的环境中无法正常工作，而是安装0.3.21。

我已经这样做了，但现在基本上我输入的每个VMC命令都会出现以下错误。我试过重新安装Ruby、Sinatra和VMC，但仍然会出现同样的错误。有什么想法吗？

为什么建议您卸载最新版本？可能存在gem依赖性问题，但这些问题已经得到解决。
