用RSpec进行Ruby测试

我正在尝试使用Rspec和Bundler进行一些简单的ruby（没有rails）测试。 从命令行im running

$bundle exec rspec spec/hello\u example.rb

我没有收到指向spec_helper.rb文件的方法错误，如下所示：

我的计算机上安装了Rpec 2.99版和3.2.3版。Bundler通知我它正在使用2.99版。我猜我必须切换Bundler，让它使用Rspec版本3.2.3。谁能告诉我如何确保Bundler运行的是3.2.3版。或者其他我可以解决这个问题的方法。非常感谢你

在项目根目录中创建：

source "http://rubygems.org"
gem "rspec", '~> 3.2.3'

你好，谢谢你的回答。我以前也在bundler网站上通过Your's链接阅读过这篇文章，但我并不完全清楚如何创建一个文件。谢谢，所以muchIt是一个名为“Gemfile”（无文件扩展名）的纯文本文件，它位于应用程序/脚本根目录中。打开一个简单的文本编辑器，用上面的内容创建一个新文件，并将其保存为名为“Gemfile”的纯文本。感谢@tessi的扩展谢谢您的解释。我做了上面提到的所有事情，但我仍然收到相同的错误消息您是否将文件放在了错误的文件夹中？它需要位于您正在运行的文件夹中。

$bundle exec rspec spec/hello_example.rb

。通过查看堆栈跟踪，您有两个嵌套的spec文件夹：

/Users/rockyboy/test ruby/spec/spec/

。
