我想在我的Ubuntu 11.04系統中將Rails 2.3.5升級到3.2.8。我安裝了紅寶石和紅寶石寶石。我還安裝了所需的庫。我按照以下鏈接 http://cicolink.blogspot.in/2010/10/how-to-install-ruby-rails-and.html在Ubuntu中安裝rails 3 11.04
但是當我運行sudo的創業板在命令行
WARNING: Error fetching data: SocketError: getaddrinfo: Name or service not known (http://rubygems.org/latest_specs.4.8.gz)
WARNING: Error fetching data: SocketError: getaddrinfo: Name or service not known (http://rubygems.org/specs.4.8.gz)
ERROR: While executing gem ... (Gem::DependencyError)
Unable to resolve dependencies: mail requires mime-types (~> 1.16), treetop (~> 1.4.8)
我一直在試圖找出這對最後2天安裝導軌我碰到下面的錯誤。請幫助
(但是,當我執行sudo apt-get的安裝安裝成功Rails2.3.5軌)
