“轨生成RSpec的：安装”似乎没有

运行：红宝石1.9.3p0使用Rails 3.2.1

尝试使用rspec的，但是当我尝试把它安装到我的应用程序，我得到以下错误：

/Users/Si/.rvm/gems/ruby-1.9.3-p0/gems/railties-3.2.1/lib/rails/railtie/configuration.rb:85:in `method_missing': undefined method `generators' for #<Rails::Railtie::Configuration:0x00000101b2f1b8> (NoMethodError)

from script/rails:6:in `<main>' 

我对rails和ruby很新，所以这对我来说几乎没有任何意义，任何人都可以解释。

感谢

它看起来像你的RSpec的护栏版本2.0.0.beta ... 尝试升级这〜> 2.8，或者如果这是你已经在你的Gemfile指定的内容，运行bundle exec rails g rspec:install

要更新版本的宝石，你的Gemfile您应该具备以下条件：

group :test, :development do 
    gem "rspec-rails", "~> 2.8" 
end 

一旦你补充说，运行bundle update rspec-rails然后再次尝试安装，一切都应该一诺千金！
