为什么我得到“未定义的方法或变量'example'”？在RSpec 3.0中？ [英] Why do I get "undefined method or variable 'example'" in RSpec 3.0?

问题描述

升级到RSpec 3.0后，我收到以下消息：

After upgrading to RSpec 3.0, I got the following message:

 Failure/Error: Unable to find matching line from backtrace
 NameError:
   undefined local variable or method `example' for #<RSpec::ExampleGroups::Anonymous:0x007f9ae985b548>

即使将规范降低为以下内容，消息仍然存在：

The message persisted even after reducing the spec to the following:

describe "" do
  it "" do
  end
end

我确实注意到水豚位于栈顶附近，如下所示：

I did notice capybara was near the top of the stack, as follows:

 # /Users/palfvin/.rvm/gems/ruby-2.0.0-p247@botmetrics/gems/capybara-2.1.0/lib/capybara/rspec.rb:20:in `block (2 levels) in <top (required)>'

的情况下。

推荐答案

此错误是由于在继续运行Capybara 2.1.0的同时安装RSpec 3.0.0.beta引起的。如果安装Capybara 2.2.0.beta，错误将消失。

This error results from installing RSpec 3.0.0.beta while continuing to run Capybara 2.1.0. If you install Capybara 2.2.0.beta, the error will go away.
