我在Rspec 1.3的rails 2.3.8应用程序中设置capybara(0.4.1.2)遇到了一些麻烦，从安装capybara的说明中，我插入了以下行:
require 'capybara/rspec'
然而，这给了我一个缺失的常数错误。似乎它正在寻找一个类'RSpec'没有加载(我猜这是一个RSpec 2/Rails 3的东西)。
那么我如何让Rspec在rails 2.3下识别水豚呢?我应该使用早期版本的capy吗?

Capybara没有内置对RSpec 1.x的支持。但是，你可以使用Steak来代替你自己的RSpec支持。
如果您只是想做'请求规格'(如railscasts的"我如何测试"中所定义的那样)，那么牛排似乎并不真正需要。参见:除了在Rails测试中使用Capybara和RSpec之外，Steak还添加了什么?
我刚刚设置了rails 2.3 + rspec 1 + capybara(最新版本)，没有任何麻烦
你不能有require capybara/rspec，但似乎它所做的就是添加一些匹配器…但真正重要的是水豚及其DSL和验证内容
Capybara适用于任何机架应用程序
on my spec_helper.rb:
require 'capybara/rails'
include Capybara::DSL
就是这样(只要点击文档中的Capybara，它是DSL因为某些方面的Capybara匹配器可能会丢失，没有什么会阻塞，虽然)
从Capybara文档，
Note that Capybara’s built in RSpec support only works with RSpec 2.0 or later. You’ll need to roll your own for earlier versions of RSpec.
