我正在试火车。我正在使用 网站了解更多关于rails3的信息；本教程从一开始就非常好（我对rails2的经验很少）

我与rspec有一个问题，目前阻碍了我的进度。我看到教程推荐使用rspec2.0.0.beta.18 gem；我改为使用安装rspec2.0.0.beta.20 gem

bundle install
但是，我发现这个版本的rspec存在问题 我的集成测试rspec如下所示：

describe "LayoutLinks" do
  it "should have a About page at '/about'" do  
    get '/about'
    response.should have_selector('h1', :content => "About Us")
  end 
end

Failures:
  1) LayoutLinks should have a About page at '/about'
     Failure/Error: Unable to find matching line from backtrace
     stack level too deep
     # /home/arun/.rvm/rubies/ruby-1.9.2-p0/lib/ruby/1.9.1/forwardable.rb:185
失败看起来像：

describe "LayoutLinks" do
  it "should have a About page at '/about'" do  
    get '/about'
    response.should have_selector('h1', :content => "About Us")
  end 
end

Failures:
  1) LayoutLinks should have a About page at '/about'
     Failure/Error: Unable to find matching line from backtrace
     stack level too deep
     # /home/arun/.rvm/rubies/ruby-1.9.2-p0/lib/ruby/1.9.1/forwardable.rb:185
（注意：那些看过的人在理解上下文时不会有问题。）

如果我在Gemfile中将rspec版本更改为2.0.0.beta.18并运行rspec，则会出现以下错误

第二个错误应该通过在更改文件时重新运行
bundle install
来修复

至于第一个错误，您能发布routes.rb文件中定义“/about”路由的行吗？

我再次运行了“bundle install”，当我查看Gemfile和Gemfile.lock时，无论我使用的是2.0.0.beta.18还是2.0.0.beta.20，我都会找到相应的gems

routes.rb映射/关于属于特定控制器的特定操作。当我在浏览器中访问页面时，我也会得到正确的页面；因此，我认为这不是问题所在。（很遗憾，我现在没有代码，无法将其粘贴到此处）

以下是我无法理解的错误

arun@ubuntu-world:~/Project/Rails/rails3/sample_app$ rspec spec/
/home/arun/.rvm/gems/ruby-1.9.2-p0/gems/bundler-1.0.0/lib/bundler/runtime.rb:27:in `block in setup': You have already activated rspec-core 2.0.0.beta.20, but your Gemfile requires rspec-core 2.0.0.beta.18. Consider using bundle exec. (Gem::LoadError)
我知道bundle exec是什么，更不用说如何使用它了

--Arun

您需要使用gem卸载删除其中一个gem：

$gem卸载rspec内核-v2.0.0.beta.20

您还可以使用gem list查看您安装的gems的版本。

Rspec在Hartl教程的11章中一直运行良好。但不知何故，我弄乱了我的gemfille，我开始遇到同样的问题，rspec“堆栈级别太深”，无法通过“捆绑安装”解决。于是我疯狂地做了一个梦

windows> gem uninstall rspec rspec-rails rspec-expectations rspec-mock rspec-core
（所有版本）。'“创业板名单”显示他们确实都走了。然后我执行了一个命令

> bundle install
...
Using rspec-core (2.0.0.beta.22)
Using rspec-expectations (2.0.0.beta.22)
Using rspec-mocks (2.0.0.beta.22)
Using rspec (2.0.0.beta.22)
Using rspec-rails (2.0.0.beta.22)
...
这就是我档案中的内容。然而，一个“gem列表-d rspec”仍然显示没有安装rspec或rspec xxx gem以及rspec核心问题

> rails g rspec:install       *#for good measure*
...
> rspec -v
C:/Ruby192/lib/ruby/1.9.1/rubygems.rb:762:in `report_activate_error': Could not 
find RubyGem rspec-core (>= 0) (Gem::LoadError)
但“捆绑列表”显示它已安装。那么，如何让rspec再次工作

更新

我解决了这个问题，但首先我要向阿伦·库马尔（arun kumar）致以最谦卑的歉意，因为他对自己的问题不屑一顾，并在问题和答案之间插手。我认为我的问题是类似的，我的“答案”是最后的位置。 首先，我必须做一个测试

> gem install rspec -v 2.0.0.beta.22
> gem install rspec-rails -v 2.0.0.beta.22
而不是期望bundler这样做。bundler在这里似乎不可靠。这使我对rspec的调用再次起作用，但我仍然必须处理“堆栈级别太深”的问题。这是通过将rspec和rspec rails升级到2.0.1（来自David Chelimski:）来解决的。再次更改我的Gemfile并调用bundle安装没有起作用。我必须卸载所有五个rspec xxx gems，就像上面所说的那样，然后手动执行

> gem install rspec -v 2.0.1
> gem install rspec-rails -v 2.0.1
也许我不需要先卸载，但我确实卸载了。海报很可能已经解决了他的问题，因为那是很久以前的事了，但这里是我的解决方案，可能对其他人有用——回想一下我有Windows Vista64。

我也有同样的问题。此时，来自/spec/requests/layout\u links\u spec.rb的测试都失败，并出现相同的错误（控制器测试工作正常）：

在对/spec/request执行一些故障排除之后 
require 'spec_helper'

describe "LayoutLinks" do

  it "should have a Home page at '/'" do
    get '/'
    response.should have_selector('title', :content => "Home")
  end

  it "should have a Contact page at '/contact'" do
    get '/contact'
    response.should have_selector('title', :content => "Contact")
  end

  it "should have an About page at '/about'" do
    get '/about'
    response.should have_selector('title', :content => "About")
  end

  it "should have a Help page at '/help'" do
    get '/help'
    response.should have_selector('title', :content => "Help")
  end
end
