【问题描述】：

我有一个 Rails 3.2 应用程序。我正在尝试设置黄瓜测试以使用 Google chrome 运行。我已经添加了相同的配置：

Capybara.register_driver :selenium do |app|
  Capybara::Selenium::Driver.new(app, :browser => :chrome)
end

另外，我已经在 /usr/bin/ 中安装了 chromedriver 及其二进制文件：

➜  ~  ls -lah /usr/bin | grep chrome
-rwxrwxrwx  1 root   root     18M May 20 15:42 chromedriver
lrwxrwxrwx  1 root   root      32 Apr  6 10:19 google-chrome -> /opt/google/chrome/google-chrome

当我尝试运行一个仅打开 google.com 并搜索某些内容的简单功能时，我收到以下错误：

unexpected response, code=404, content-type=""
      unknown command: session/url (Selenium::WebDriver::Error::WebDriverError)
      ./features/step_definitions/google_steps.rb:2:in `/^I am on the google page$/'
      features/google.feature:3:in `Given I am on the google page'

跟踪的其余部分：

      unknown command: session/url (Selenium::WebDriver::Error::WebDriverError)

      /home/arkiver/.rvm/gems/ruby-1.9.3-p392@tests/gems/capybara-2.1.0/lib/capybara/cucumber.rb:10:in `After'

需要帮助弄清楚我在这里缺少什么。

【解决方案1】：

我解决了这个问题。我（不小心？）使用了错误的驱动程序版本：

从https://code.google.com/p/chromedriver/downloads/list，我下载了这个版本：

" chromedriver_linux64_26.0.1383.0.zip ChromeDriver server for linux64"

而不是我之前选择的：

"chromedriver2_linux64_0.8.zip版ChromeDriver2 r195627 Release"

这样就解决了。

【解决方案2】：

我遇到了同样的问题。就我而言，我有最新的驱动程序，但我还需要将我正在使用的 selenium gem 更新到最新版本。
