運行：紅寶石1.9.3p0使用Rails 3.2.1

嘗試使用rspec的，但是當我嘗試把它安裝到我的應用程序，我得到以下錯誤：

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

我對rails和ruby很新，所以這對我來說幾乎沒有任何意義，任何人都可以解釋。

感謝

它看起來像你的RSpec的護欄版本2.0.0.beta ... 嘗試升級這〜> 2.8，或者如果這是你已經在你的Gemfile指定的內容，運行bundle exec rails g rspec:install

要更新版本的寶石，你的Gemfile您應該具備以下條件：

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

一旦你補充說，運行bundle update rspec-rails然後再次嘗試安裝，一切都應該一諾千金！
