我是想，因爲它需要安裝引入nokogiri的軌道可啓動錯誤與Mac上安裝引入nokogiri當「sudo的創業板安裝引入nokogiri」
$ rails s
/usr/local/rvm/gems/[email protected]/gems/bundler-1.1.5/lib/bundler/spec_set.rb:90:in `block in materialize': Could not find nokogiri-1.5.5 in any of the sources (Bundler::GemNotFound)

然而，它沒有當我試圖與安裝引入nokogiri命令
$ sudo gem install nokogiri
這是錯誤。
