ruby 安装错误，gem http 403

 在配置gem的过程中，有极小机率会遇到gem安装后失效的问题，比方说会403，如下所示：

C:\Users\geraldlau>gem update --system
Updating RubyGems...
ERROR:  While executing gem ... (Gem::RemoteSourceException)
    HTTP Response 403

C:\Users\geraldlau>gem install rubygems-update
ERROR:  While executing gem ... (Gem::RemoteSourceException)
    HTTP Response 403

C:\Users\geraldlau>gem sources -r http://gems.rubyforge.org
ERROR:  While executing gem ... (Gem::RemoteSourceException)
    HTTP Response 403

 

这是一个很神奇的事情，所以说这个世界充满了奇妙。遇到这个问题，本地是无论如何都没法使用gem的了，只有去官方重新下载最新版的gem，本地安装后才能修复。

直接到http://rubyforge.org/frs/?group_id=126，下载最新版本的gem，然后本地安装。如果是win环境，建议拉zip包，若在linux下面，就随便拉哪种都行了。把gem包拉到本地并解压后，安装它：

C:\>cd rubygems-1.3.5

C:\rubygems-1.3.5>dir/w
