我在 Ruby 中使用 Capybara 和 Selenium（不在测试框架内。）

如果我打开一个 ruby​​ 控制台并运行该方法，它可以工作，但如果我再次运行相同的方法，我会收到此错误。

代码如下：

class ExampleClass
  include Capybara::DSL

  def do_capybara

    Capybara.app_host =  "http://example.com"
    Capybara.run_server = false
    Capybara.current_driver = :selenium

    visit '/'

    page.driver.browser.close

    Capybara.reset_sessions!
  end

您可以在设置一些默认时间后尝试吗？

Capybara.default_wait_time = 10

只需在设置当前驱动程序后给出此评论。它可以帮助你克服这个问题。
