Onemonth Rails教程gemfile不會讓我捆綁安裝

我正在做一個月的rails教程，遇到我似乎無法修復的小問題。我無法在這個簡單的網站上獲得一些引導程序的功能，因此認爲這是一個與未更新寶石有關的問題，我去了Bootstrap網站，我試圖更新它所說的寶石[寶石 '自舉薩斯'， '〜> 3.1.1']所以Onemonth Rails教程gemfile不會讓我捆綁安裝

在我的寶石文件從我只是有

gem 'bootstrap-sass'

到

gem 'bootstrap-sass', '~> 3.1.1'

去也注意到了教程此代碼在寶石文件中

group :doc do 
     #bundle exec rake doc:rails generates the API under doc/api 
    gem 'sdoc', require: false 
    end

，所以我補充說，還有，安裝捆綁，重新啓動服務器導軌是並沒有解決問題，所以試圖要回什麼之前，得到了下面的錯誤..

You cannot specify the same gem twice with different version requirements. 
    You specified: sdoc (~> 0.4.0) and sdoc (>= 0)

繼承人什麼我的寶石文件現在看起來像，現在我試圖綁定安裝並推送到heroku，但這個錯誤信息不會讓我。下面

source 'https://rubygems.org' 

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'

gem 'bootstrap-sass', '~> 3.1.1' 

group :development, :test do 
    gem 'sqlite3' 
end 


group :production do 
    gem 'pg' 
    gem 'rails_12factor' 
end 



group :doc do 
# bundle exec rake doc:rails generates the API under doc/api 
gem 'sdoc', require: false 
end

GEM文件應我剛纔讀從哈特爾Rails的書在引擎蓋下更好的理解？

您已經於您的Gemfile與導致錯誤的不同版本指定gem 'sdoc'兩次：

You cannot specify the same gem twice with different version requirements. 
You specified: sdoc (~> 0.4.0) and sdoc (>= 0)

請看下圖：

source 'https://rubygems.org' 
##... 
##... 
gem 'sdoc', '~> 0.4.0',   group: :doC##<-- First 
##... 
##... 
group :doc do 
# bundle exec rake doc:rails generates the API under doc/api 
gem 'sdoc', require: false ##<-- Second 
end

刪除其中不需要一個和運行bundle install
