Cucumber 硒模式下的黄瓜和大鼠：Can'；使用gem bundle时不要启动mongrel_rails

我正在使用gem bundler（v.0.9.6）和Rails 2.3.5、rubygems 1.3.6和ruby 1.8.7（在雪豹上）。我的文件如下所示：

source :rubyforge
source "http://gems.github.com"

gem "rails", "2.3.5"
gem "ruby-debug"
gem "activemerchant", :require => 'active_merchant'
gem "hpricot"
gem "nokogiri"
gem "state_machine"
gem "fastercsv"
gem "yubikey"
gem "httparty"
gem "ruby-openid"
gem "mongrel" 

group :development do 
  gem 'mongrel'
end

#teste
group :test do
  gem 'rspec'  
  gem 'rspec-rails'
  gem 'cucumber' 
  gem 'cucumber-rails'
  gem "mechanize"
  gem 'notahat-machinist', :require => 'machinist'
  gem 'faker'
  gem 'webrat'
  gem 'selenium-client'
  gem 'database_cleaner'
  gem 'fakeweb'
  gem 'mongrel' #Selenium needs this
end

到目前为止还不错。我已经成功地使用bundler几个星期了。然而，我开始在Selenium模式下使用Cucumber和WebRat来测试站点的一些ajaxy功能，每当我运行该功能时，WebRat都会告诉我Rails服务器已经启动，但我总是遇到XHR_错误，Selenium无法找到URL嗯，碰巧服务器没有启动。

然后，我打开webrat/lib/webrat/selenium/application\u servers/rails.rb文件，并在start方法中放入一条调试器语句。再次运行该功能，当调试器触发时，我打印了start_命令def的返回，它是：

mongrel_rails start -d --chdir='/Users/fullofcaffeine/Projetos/myproject' --port=3001 --environment=test --pid /Users/fullofcaffeine/Projetos/myproject/tmp/pids/mongrel_selenium.pid 

我复制并粘贴到控制台中，从末尾删除了-d和&这是我得到的输出：

检查它试图从“~/.bundle/…”加载mongrel的路径，但mongrel是作为系统gem安装的。Bundle在其他上下文中处理系统gems的加载，但在这个特定的情况下，我不知道它为什么会失败：（

我尝试再次运行“捆绑安装”，它总是说：

从系统安装mongrel（1.1.5） 宝石

我已经尝试从系统中卸载mongrel到尝试制作bundle将其安装到~/.bundle（因为这似乎是错误的根源，因为mongrel正在这个路径中搜索，所以我启动了mongrel\u rails，如上所述），但我就是做不到

gem uninstall mongrel
ERROR:  While executing gem ... (Gem::InstallError)
    cannot uninstall, check `gem list -d mongrel`

当我运行“gem list | grep mongrel”时，我得到：

奇怪

我只想在使用gem bundler时能够成功运行Cucumber和WebRat+Selenium，但这让我发疯

---

有谁能给我点启发吗？

嗯，我找到了一个解决办法，有点可疑，但很有效：

 cp  /Library/Ruby/Gems/1.8/gems/mongrel-1.1.5/ mongrel-1.1.5

现在，如果您尝试：

mongrel_rails start --chdir='/Users/fullofcaffeine/Projetos/myproject' --port=3001 --environment=test --pid /Users/fullofcaffeine/Projetos/myproject/tmp/pids/mongrel_selenium.pid

它将找到mongrel并启动服务器，然后您可以运行使用Selenium的Cucumber功能，它将工作：）

如果其他人发现或知道有关此问题的任何其他信息，请分享，这可能最终成为某个地方的bug

我也遇到了类似的问题，但结果是/Users/{account}/.gems/和/Library/Ruby/gems/（默认安装）或/opt/local/lib/Ruby/gems/（Mac端口安装）中安装的gems版本不匹配。当我删除/Users/{account}/.gems/时，一切都正常了。

我遇到了同样的问题，并花了一段时间试图调试它。看起来Mongrel、GemPlugin和Bundler之间存在某种交互。可能的解决办法包括：

修复GemPlugin，使其与Bundler 0.9配合使用

修改Mongrel以不再使用GemPlugin

修改Webrat以支持除Mongrel之外的web服务器

由于GemPlugin和Mongrel这几天看起来都有些过时和废弃，我决定基于添加对Webrat的瘦支持

您可以，也可以将以下内容添加到您的文件中：

gem 'webrat', :git => 'git://github.com/emk/webrat.git'

…并相应地更新您的features/support/env.rb文件：

Webrat.configure do |config|
  # Add this line.
  config.application_framework = :rails_thin

  # Your previous configuration here...
end

---

尝试定位当前gem可执行文件正在使用的gems目录，并从缓存或规范目录中删除任何剩余内容，这应该会起作用。

bundle exec mongrel\u rails start…

这里的要点是从bundle加载rails gem，而不是从系统gemenv加载

我们这里有一个类似的场景：

---

您能否验证此解决方案是否从捆绑包中加载所有rails gem？还是mongrel和所有活动的*gems最终都从系统gemenv加载？

Webrat.configure do |config|
  # Add this line.
  config.application_framework = :rails_thin

  # Your previous configuration here...
end
