Ruby on rails 安装Rails\u Admin时出现问题,ruby-on-rails,ruby-on-rails-3,gem,admin,Ruby On Rails,Ruby On Rails 3,Gem,Admin,我最初添加了gem'rails\u admin'，git=>'git://github.com/sferik/rails_admin.git“到我的GEM文件，但我遇到了以下错误： Bundler could not find compatible versions for gem "rails": In snapshot (Gemfile.lock): rails (3.0.4) In Gemfile: rails_admin depends on rai

我最初添加了

gem'rails\u admin'，git=>'git://github.com/sferik/rails_admin.git“

到我的GEM文件，但我遇到了以下错误：

Bundler could not find compatible versions for gem "rails":
  In snapshot (Gemfile.lock):
    rails (3.0.4)

  In Gemfile:
    rails_admin depends on
      rails (~> 3.0.7)

rake aborted!
undefined method `task'

因此，我更新到rails 3.0.7，并从git://github.com/sferik/rails_admin.git （主控时）

我在控制台中运行

rake rails\u admin:install

，出现以下错误：

Bundler could not find compatible versions for gem "rails":
  In snapshot (Gemfile.lock):
    rails (3.0.4)

  In Gemfile:
    rails_admin depends on
      rails (~> 3.0.7)

rake aborted!
