我正在使用 SASS RailsKit

   /opt/local/lib/ruby/site_ruby/1.8/rubygems.rb:283:in `activate': Unable to activate rspec-rails-2.6.1, because activesupport-2.3.8 conflicts with activesupport (~> 3.0), actionpack-2.3.8 conflicts with actionpack (~> 3.0) (Gem::LoadError)

我对事物的看法：

ruby 1.8.7 (2010-01-10 patchlevel 249) [i686-darwin10]
/opt/local/bin/ruby
gem version 1.6.0
/opt/local/bin/gem
activerecord (2.3.8)
activeresource (2.3.8)
activesupport (2.3.8)
actionmailer (2.3.8)
actionpack (2.3.8)
rails (2.3.8)
rspec-rails (2.6.1, 1.3.4)

知道是什么原因造成的吗？

【解决方案1】：

解决此问题的最佳方法是使用 RVM 并为每个应用程序提供一个 gemset

RVM Best Pratices

rspec-rails (2.6.1) 需要 Rails 3

gem uninstall rspec-rails
