這是我安裝的版本[img]/upload/attachment/66559/d6ab9ccd-6e48-33e4-ba2e-e7f92243e064.jpg[/img]
為什么還有下面的提示？
Missing the Rails 2.2.2 gem. Please gem install -v=2.2.2 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.
另外。試下gem -v，看看是否1.3.1。
RAILS_GEM_VERSION 更新过没?
注释掉,或者修改为你现在的版本;
config/environment.rb之中,有句
RAILS_GEM_VERSION = '2.2.2' unless defined? RAILS_GEM_VERSION
與gem version要對
試一下再行一次
gem install -v=2.2.2 rails
看有否幫助。
