捆绑安装问题

好的，每当我运行“捆绑安装”，我得到这个

Bundler could not find compatible versions for gem "railties": In Gemfile: sass-rails (~> 3.1.0.rc8) depends on railties (~> 3.1.0) railties (3.1.0.rc8) 

现在在我的gem文件中我有这个：

 source 'http://rubygems.org' gem 'rails', '3.1.0.rc8' # Bundle edge Rails instead: # gem 'rails', :git => 'git://github.com/rails/rails.git' gem 'sqlite3' gem 'json' # Gems used only for assets and not required # in production environments by default. group :assets do gem 'sass-rails', " ~> 3.1.0.rc8" #added by me gem 'railties', " ~> 3.1.0.rc8" #end gem 'coffee-rails', "~> 3.1.0.rc" gem 'uglifier' end gem 'jquery-rails' # Use unicorn as the web server # gem 'unicorn' # Deploy with Capistrano # gem 'capistrano' # To use debugger # gem 'ruby-debug' 

我正在使用ubuntu，我是ruby的新手，我正在尝试运行一个简单的应用程序。

有帮助吗？ 谢谢！

由于Rails 3.1已于今天发布，您必须将Gemfile更新为：

 source 'http://rubygems.org' gem 'rails', '3.1.0' # Bundle edge Rails instead: # gem 'rails', :git => 'git://github.com/rails/rails.git' gem 'sqlite3' gem 'json' # Gems used only for assets and not required # in production environments by default. group :assets do gem 'sass-rails', " ~> 3.1.0" gem 'coffee-rails', "~> 3.1.0" gem 'uglifier' end gem 'jquery-rails' # Use unicorn as the web server # gem 'unicorn' # Deploy with Capistrano # gem 'capistrano' # To use debugger # gem 'ruby-debug' 

您不需要railties线，因为此gem包含在铁轨中。 然后，运行bundle install 。 这应该够了吧。
