Question

我想在我的Gemfile中使用最后一个版本的rails：gem 'rails', '3.0.0.beta3'

尝试启动服务器时出现此错误，您知道我如何解决此问题吗？

$rails s
/Library/Ruby/Site/1.8/rubygems.rb:777:in `report_activate_error': RubyGem version error: activesupport(1.4.4 not = 3.0.0.beta) (Gem::LoadError)
    from /Library/Ruby/Site/1.8/rubygems.rb:211:in `activate'
    from /Library/Ruby/Site/1.8/rubygems.rb:246:in `activate'
    from /Library/Ruby/Site/1.8/rubygems.rb:245:in `each'
    from /Library/Ruby/Site/1.8/rubygems.rb:245:in `activate'
    from /Library/Ruby/Site/1.8/rubygems.rb:1056:in `gem'
    from /usr/bin/rails:18

bundle install return Your bundle is complete!

宝石清单给我

activesupport (3.0.0.beta3, 2.3.5, 2.2.2, 1.4.4)

好的，所以你需要activesupport 3.0.0.beta3，而它需要activesupport 3.0.0.beta。试试这个：

gem install activesupport -v 3.0.0.beta --pre

RubyGem版本错误：activesupport（1.4.4 not = 3.0.0.beta）（Gem :: LoadError）
