python – 如何接受在Selenium中安装扩展时显示的弹出窗口？

import selenium
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
executable_path = "/usr/bin/chromedriver"
options = Options()
options.add_extension('/home/TheRookie/Downloads/extensionSamples/abhcfceiempjmchhhdhbnkbimnfpckgl.crx')
browser = webdriver.Chrome(executable_path=executable_path,chrome_options=options)

浏览器正常启动但我提示弹出窗口确认我要添加扩展名如下：

在我弹出这个弹出窗口之后,Python会很快返回,但会出现以下异常：

selenium.common.exceptions.WebDriverException: Message: u’unknown
error: failed to wait for extension background page to load:
chrome-extension://abhcfceiempjmchhhdhbnkbimnfpckgl/toolbar.htmlnfrom
unknown error: page could not be found:
chrome-extension://abhcfceiempjmchhhdhbnkbimnfpckgl/toolbar.htmln
(Driver info: chromedriver=2.12.301324
(de8ab311bc9374d0ade71f7c167bad61848c7c48),platform=Linux
3.13.0-39-generic x86_64)’

我尝试使用以下代码将弹出窗口作为常规JavaScript警报处理：

alert = browser.switch_to_alert()
alert.accept()

但是,这没有用.谁能告诉我如何在没有弹出窗口或接受弹出窗口的情况下安装此扩展程序？任何帮助将不胜感激.谢谢！
