無法從紅寶石庫中識別對象

Question

我最近更新了操作系統到ELcaptain，並且自從我的功能文件失敗並且無法識別對象。

這是我在終端得到的錯誤，當我運行一個文件：

cannot load such file -- rspec (LoadError) 
/Users/xyz/.rvm/rubies/ruby-2.1.6/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_require.rb:128:in `require'

與上步定義我得到這個錯誤：

undefined method `expect' for #<Object:0x007fb6b1d1ac80> (NoMethodError)

如果您還沒有請嘗試此操作：

運行bundle install

如果你沒有一個規範的助手或在spec目錄軌幫手，運行此：你在哪裏使用`expect` rails generate rspec:install
