我检查代理设置，它似乎罚款这个问题是有关的其他一些东西 – Sunny

你可以打印输出的'宝石环境' – Ross

这看起来像服务器无法连接到http：// gems。 rubyforge.org - 你可以尝试'curl'或'wget'来自服务器的URL来排除一个简单的连接问题吗？ –

我已经使用宝石的代理命令选项安装修复了这个问题的轨道。它具有以下格式：

$ gem install --http-proxy http://201.187.107.19:8080 rails

请注意，IP地址和端口号是指代理服务器。您应该搜索代理列表并使用其中一个代理。

这是网站与代理：http://www.cybersyndrome.net/pla5.html

另外，我必须努力才能取得成功7个或8个不同的代理。不要放弃。

注意，你可以看到下面的错误，太：

ERROR: While executing gem ... (Gem::DependencyError) 
    Unable to resolve dependencies: rails requires activesupport (= 3.2.8), actionpack (= 3.2.8), activerecord (= 3.2.8), activeresource (= 3.2.8), actionmailer (= 3.2.8), railties (= 3.2.8), bundler (~> 1.0)

不要放弃，并继续从列表中的下一个代理。祝你好运。
