出现的问题

Missing the Rails 2.3.4 gem.

完整的错误提示:

Missing the Rails 2.3.4 gem. Please `gem install -v=2.3.4 rails`, update your RAILS_GEM_VERSION setting in config/environment.rb for the Rails version you do have installed, or comment out RAILS_GEM_VERSION to use the latest version installed.

事实上，需要的gem都是安装过的，只是它找不到罢了。在config/environment.rb里添加上就好了:


ENV['GEM_PATH'] = "/home/muzik/.gem/ruby/1.8:#{ENV['GEM_PATH']}"
