$ rspec規格/不適合我。請幫助

Question

我是新來的鐵軌，這阻止了我。 我想運行rspec spec /和我得到錯誤。誰能幫我？

這是我得到的代碼：

Answer 1

使用

sudo gem update rspec-rails

Answer 2

看起來你已經安裝了RSpec的護欄寶石的舊版本。嘗試更新它（2.1.0在寫作時的最新版本）：

gem update rspec-rails 

更新如下意見：

你需要指定一個或多個規格文件或名稱包含您的spec文件的目錄。使用捆紮機

rspec spec 

在Rails項目：例如，如果你的規範文件是在一個文件夾，名爲規範，那麼這將運行所有這些

bundle exec rspec spec 

有關RSpec的命令的詳細信息：

rspec -h 

Answer 3

也許已經晚了，但對於錯誤：

No examples were matched. Perhaps {:unless=>#<Proc:0x00000001005b7790@/Library/Ruby/Gems/1.8/gems/rspec-core-2.1.0/lib/rspec/core/configuration.rb:53>, :if=>#<Proc:0x00000001005b7970@/Library/Ruby/Gems/1.8/gems/rspec-core-2.1.0/lib/rspec/core/configuration.rb:52>} is excluding everything? Finished in 0.00003 seconds 0 examples, 0 failures 

像它說，測試是不是在你的test_spec文件中找到。您應該在測試用例中添加一個「it」表達式。
