rspec是否需要安裝4個寶石？

Question

根據本教程：http://rspec.codeschool.com/levels/1（2分鐘標記）當您輸入「gem install rspec」來安裝Rspec時，應該下載4個寶石。不過，我的命令行Windows只安裝了1個寶石。

Successfully installed rspec-3.0.0 
1 gem installed 

我是否遺漏了Rspec的其他部分，如果是這樣，我該如何手動添加它們？

Answer 1

您可能已經安裝了所有的寶石。我第一次安裝rspec的我得到安裝了6個寶石：

> gem install rspec 

Fetching: rspec-support-3.0.4.gem (100%) 
Successfully installed rspec-support-3.0.4 
Fetching: rspec-core-3.0.4.gem (100%) 
Successfully installed rspec-core-3.0.4 
Fetching: diff-lcs-1.2.5.gem (100%) 
Successfully installed diff-lcs-1.2.5 
Fetching: rspec-expectations-3.0.4.gem (100%) 
Successfully installed rspec-expectations-3.0.4 
Fetching: rspec-mocks-3.0.4.gem (100%) 
Successfully installed rspec-mocks-3.0.4 
Fetching: rspec-3.0.0.gem (100%) 
Successfully installed rspec-3.0.0 
6 gems installed 

但一旦安裝所有的寶石，RSpec的再次安裝只顯示1顆寶石安裝：

> gem install rspec 

Successfully installed rspec-3.0.0 
1 gem installed 

要確認所安裝的寶石，運行：

gem list
