[英]Watir - Error when I try to take screenshot of div
我使用Watir和Watir-element-screenshot獲取元素的屏幕截圖。 瀏覽器:Chrome和Firefox(最新版本)我的代碼:
require 'watir'
require 'watir/extensions/element/screenshot'
browser = Watir::Browser.new :firefox
browser.goto 'google.com.ua'
browser.text_field(id: "lst-ib").set "ruby\n"
browser.window.maximize
browser.element(id: "resultStats").screenshot("2.png")
browser.close
並采取以下錯誤:

此消息的原因是什么,我該如何修復?
您可以使用此代碼進行屏幕截圖並保存在特定位置。
browser.screenshot.save("path to save image/2.png")
