Ruby on rails 3 $rspec spec/不为我工作。请帮忙

我是rails新手，这让我停滞不前。 我正在尝试运行rspec spec/但出现错误。有人能帮我吗

这是我得到的代码：

看起来您已经安装了旧版本的rspec-rails-gem。尝试更新它（2.1.0是撰写本文时的当前版本）：

更新了以下评论：

您需要指定一个或多个等级库文件的名称或包含等级库文件的目录。例如，如果等级库文件位于名为“等级库”的文件夹中，则这将运行所有等级库文件：

rspec spec

在使用Bundler的Rails项目中：

bundle exec rspec spec

有关rspec命令的更多信息：

rspec -h

使用

sudogem更新rspec-rails

可能是迟到了，但由于错误：

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

没有匹配的示例。也许{：除非=>#，：如果=>#}排除了一切？在0.00003秒内完成0个示例，0个失败

正如上面所说，在测试规范文件中没有找到测试。您应该在测试用例中添加一个“it”表达式。

我发现没有匹配的示例。也许{：除非=>#，：如果=>#}排除了一切？在0.00003秒内完成0个示例，0个失败。您已通过原始错误，现在“没有匹配的示例”？这表明rspec正在工作，但找不到您的测试。非常感谢您的帮助。你对我该做什么有什么想法吗？
