在Windows环境下搭建OpenShift环境，安装客户端工具rhc，首先需要安装Ruby和Git，参阅https://developers.openshift.com/en/getting-started-client-tools.html#windows。
在正确安装Ruby和Git之后，使用RubyGems包管理器（Ruby内置）安装OpenShift的客户端工具rhc。
官方提供的方式为：gem install rhc，但可能是网络原因所致，执行命令后提示错误信息：
ERROR: Could not find a valid gem 'rhc' (>= 0), here is why:
Unable to download data from https://rubygems.org/ - Errno::ECONNREFUS
ED: No connection could be made because the target machine actively refused it.
- connect(2) (https://rubygems.org/latest_specs.4.8.gz)
参阅StackOverFlow的一个解答：http://stackoverflow.com/questions/19745960/unable-to-install-any-gem-by-ruby-in-windows
“This is most likely due to running over a secure (https) connection to rubygems.org. Look at the help for “gem sources –h”, remove the https version and add http://rubygems.org”
问题仍然没有解决。
实际上，gem install支持本地方式安装，即将gem包下载到本地后再执行gem install --local，参阅http://stackoverflow.com/questions/220176/how-can-i-install-a-local-gem
rhc-1.30.2依赖的gem包列表如下：
- http://rubygems.org/downloads/archive-tar-minitar-0.5.2.gem
- http://rubygems.org/downloads/commander-4.2.0.gem
- http://rubygems.org/downloads/highline-1.6.21.gem
- http://rubygems.org/downloads/httpclient-2.4.0.gem
- http://rubygems.org/downloads/net-scp-1.2.1.gem
- http://rubygems.org/downloads/net-ssh-2.9.1.gem
- http://rubygems.org/downloads/net-ssh-gateway-1.2.0.gem
- http://rubygems.org/downloads/net-ssh-multi-1.2.0.gem
- http://rubygems.org/downloads/open4-1.3.4.gem
- http://rubygems.org/downloads/rhc-1.30.2.gem
将上述gem文件下载至本地目录下，然后在该目录下执行
gem install rhc --local . hc-1.30.2.gem

后来好不容易能在线gem install rhc了，但是一rhc setup就报错，想起来ruby devkit没装
其实就在rubyInstaller的下面。另外我从前虽然在mac下，也是直接让eclipse去发布maven项目的，那样就不用rhc命令行这么麻烦。
还有由于怀疑ruby版本的问题，gem install pik来代替rvm查看和切换ruby版本。
还有为了follow人家的tornado与angular项目，把python的pip也装了。
事已至此，干脆把我的createjs项目就放在python后台上面吧：
rhc create-app createjs python-2.7 postgresql-9.2 --from-code=https://github.com/haimingpro/createjs.git
postgresql-9.2 那截我删了，暂时不想要数据库了，何况还是个我没听过的，数据库和Jenkins都可以后面加，不像后台得拆掉重建。。
然而ruby卸载了重装了，devkit也成功有效的工作着，还是setup不了rhc。
最后还是这篇文章救了我！

说到底还是编译的 Ruby 2.3.0 缺少 openssl但是make这种解决方式不适合windows，
说白了装一个名叫net-ssh的gem药到病除。
