Question

最初，我在我的Windows 7中安装了ruby 1.9.3版本，我最近安装了ruby 2.0.0p195，并且已经通过命令提升（ruby -v; ruby -e "puts 100"; irb）进行了测试。

ruby -v提供ruby 2.0.0p195 (2013-05-14) [i386-mingw32]

gem -v给了我2.0.2

当我尝试安装rails时，我总是会收到以下错误：

C:\Users\san>gem install rails --source http://rubygems.org
ERROR:  Could not find a valid gem 'rails' (>= 0), here is why:
          Unable to download data from https://rubygems.org/ - Errno::ETIMEDOUT:
 A connection attempt failed because the connected party did not properly respon
d after a period of time, or established connection failed because connected hos
t has failed to respond. - connect(2) (https://rubygems.org/latest_specs.4.8.gz)

或

https://rubygems.org

由于我收到了很多错误，我已经卸载了两个ruby版本并重新启动系统并重新安装（如google搜索和几个stackoverflow问题后的建议）。但没多大帮助。注意：我已关闭Windows防火墙并尝试安装。但我仍然遇到openSSL问题的异常。请对此提出建议。谢谢！

问题可能是因为您在代理/防火墙之后阻止您从rubygems.org下载。有关类似问题，请参阅rubygems.org上的以下主题：

http://help.rubygems.org/discussions/problems/799-ruby-gem-install-problems-on-windows-xp

安装时尝试使用--http-proxy选项。

对于无法通过--http-proxy工作的人，请尝试以下操作。从下面的评论添加。

gem install rails --http-proxy --source http://rubygems.org --debug -v

由于windows中的openssl / ETimedout，gem install rails无法正常工作
