Question

根据本教程：http://rspec.codeschool.com/levels/1（2分钟标记）当您输入“gem install rspec”安装Rspec时，它应该下载4颗宝石。但是我的命令行Windows只安装了1个gem。

Successfully installed rspec-3.0.0
1 gem installed

我是否遗漏了Rspec的其他部分，如果是这样，我该如何手动添加它们？

您可能已经安装了所有宝石。我第一次安装rspec时，我安装了6个宝石：

> 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

但是一旦安装了所有宝石，再次安装rspec只会显示1个gem：

> gem install rspec

Successfully installed rspec-3.0.0
1 gem installed

要验证安装了哪些gem，请运行：

gem list

rspec安装是否需要安装4个宝石？
