首先，感谢各位的回复哈，事实证明是楼猪脑子进翔了，我在 RubyGems Package Manager 可以敲入 gem install 命令了，但是远程的时候一直报错，难道是我网速的问题？求教各位继续批判。 C:\Ruby>gem install redcloth ERROR: http://gems.rubyforge.org/ does not appear to be a repository ERROR: could not find gem redcloth locally or in a repository

C:\Ruby>gem install hpricot ERROR: http://gems.rubyforge.org/ does not appear to be a repository ERROR: could not find gem hpricot locally or in a repository C:\Ruby>gem list --remote

*** REMOTE GEMS ***
