安装成功Ruby和git以后。执行rhc setup时提演示样例如以下错误：

解决方法例如以下：

Updating net-ssh to 2.9.3.beta1 (as cremno suggested in a comment above) resolved my problem:

For unix:

get install net-ssh -v 2.9.3.beta1

For windows:

gem install net-ssh -v 2.9.3.beta1

Before that I tried, but it didn‘t help:

get install net-ssh
