我在学习使用OpenShift的getting started指南时遇到了错误。OpenShift Client Tools（RHC）的设置向导会帮助我上传SSH密钥、设置应用命名空间，并检查Git等程序是否安装。

我一直在跟踪 getting started的openshift,但我遇到了这个错误.

OpenShift Client Tools (RHC) Setup Wizard This wizard will help you upload your SSH keys, set your application namespace, and check that other programs like Git are properly installed. If you have your own OpenShift server, you can specify it now. Just hit enter to use the server for OpenShift Online: openshift.redhat.com. Enter the server hostname: |openshift.redhat.com| C:/Ruby193/lib/ruby/gems/1.9.1/gems/highline-1.6.21/lib/highline.rb:86 4:in `gets': Invalid argument - <STDIN> (Errno::EINVAL) from C:/Ruby193/lib/ruby/gems/1.9.1/gems/highline-1.6.21/lib/highline.rb:864:in `get_line' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/highline-1.6.21/lib/highline.rb:885:in `get_response' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/highline-1.6.21/lib/highline.rb:260:in `ask' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rhc-1.38.4/lib/rhc/highline_extensions.rb:12:in `block (2 levels) in <c lass:HighLineExtension>' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rhc-1.38.4/lib/rhc/wizard.rb:188:in `block in server_stage' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rhc-1.38.4/lib/rhc/highline_extensions.rb:190:in `call' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rhc-1.38.4/lib/rhc/highline_extensions.rb:190:in `section' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rhc-1.38.4/lib/rhc/highline_extensions.rb:204:in `paragraph' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rhc-1.38.4/lib/rhc/helpers.rb:339:in `block (2 levels) in <module:Helpe rs>' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rhc-1.38.4/lib/rhc/wizard.rb:185:in `server_stage' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rhc-1.38.4/lib/rhc/wizard.rb:67:in `block in run' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rhc-1.38.4/lib/rhc/wizard.rb:65:in `each' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rhc-1.38.4/lib/rhc/wizard.rb:65:in `run' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rhc-1.38.4/lib/rhc/commands/setup.rb:57:in `run' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rhc-1.38.4/lib/rhc/commands.rb:294:in `execute' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rhc-1.38.4/lib/rhc/commands.rb:285:in `block (3 levels) in to_commander ' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/commander-4.2.1/lib/commander/command.rb:180:in `call' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/commander-4.2.1/lib/commander/command.rb:180:in `call' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/commander-4.2.1/lib/commander/command.rb:155:in `run' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/commander-4.2.1/lib/commander/runner.rb:421:in `run_active_command' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rhc-1.38.4/lib/rhc/command_runner.rb:72:in `run!' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/commander-4.2.1/lib/commander/delegates.rb:12:in `run!' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rhc-1.38.4/lib/rhc/cli.rb:37:in `start' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/rhc-1.38.4/bin/rhc:20:in `<top (required)>' from C:/Ruby193/bin/rhc:23:in `load' from C:/Ruby193/bin/rhc:23:in `<main>'

我尝试将ruby(和rhc gem)重新安装到旧版本(1.93),如同在另一个问题中找到的那样.它可能不是导致我的错误的原因.我尝试使用defauld windows命令行和PowerShell 5.0,结果相同.

我期待服务器主机名的提示,但是这个堆栈跟踪在进入’rhc setup’后立即发生.

我试过一切都没有用,除了 this说“更改CMD窗口属性.只需选择’使用旧版控制台’”它真的有用
