Rspec 恶鬼：尝试单击特定链接时出现超时错误

我试图点击一个链接，由于超时错误，它显示“无法点击链接”。但是这个链接在页面上是可见的

require 'spec_helper'

      describe 'Test this page', :js => true do
        it "test sample" do 
        # Resize the screen to System co-ordinates
        page.driver.resize(1366,768)

        # URL to be triggered
        visit("https://URL")
        sleep 5
        puts "Hit Page"
        page.driver.render('HitPage.jpg', :full =>true)

        # Sign in with Google credentials
        click_link "Sign in with Google Oauth2"
        sleep 2
    end
        # Entering credentials of Google Auth
        it "Enter credentials" do
            puts "Session"
        page.driver.render('googlepage.jpg', :full =>true)
        fill_in "Email",:with => "username"
        fill_in "Passwd",:with => "password"
        click_button "Sign in"
        sleep 5
        page.driver.render('loggedin.jpg', :full =>true)
    end
    end

链接显示在屏幕截图（HitPage.jpg）中，也可以单击。但当通过“rspec spec/test_spec.rb”执行时，输出显示超时错误，如下所示

Failure/Error: click_link "Sign in with Google Oauth2"

 Capybara::Poltergeist::TimeoutError:
   Timed out waiting for response to {"name":"click","args":[1,0]}. It's possible that this happened because something took a very long time (for example a page load was slow). If so, setting the Poltergeist :timeout option to a higher value will help (see the docs for details). If increasing the timeout does not help, this is probably a bug in Poltergeist - please report it to the issue tracker.
