用seleniumPython驱动器Opera

Question

我添加到我的环境变量

SELENIUM_SERVER_JAR = C:\selenium_drivers\selenium-server-standalone.jar

我在这里下载的http://selenium-
release.storage.googleapis.com/index.html?path=2.46/

Python脚本：

from selenium import webdriver

webdriver.Opera()

输出：

我期望jar定义了所有内容，为什么找不到驱动程序类？

Answer 1

根据您的问题，您似乎正在使用适用于Opera 12及更高版本的旧驱动程序。假设您尝试使用最新版本的Opera，则需要使用以下站点上提供的驱动程序：
OperaChromiumDriver

该站点列出了示例python代码，我已经确认它们可以在我的机器上打开并驱动Opera：
OperaChromiumDriver的Python示例

import time

from selenium import webdriver
from selenium.webdriver.chrome import service


webdriver_service = service.Service('C:\\Users\\Kris\\Downloads\\WinPython-32bit-2.7.9.2\\operadriver.exe')
webdriver_service.start()

driver = webdriver.Remote(webdriver_service.service_url, webdriver.DesiredCapabilities.OPERA)

driver.get('https://www.google.com/')
input_txt = driver.find_element_by_name('q')
input_txt.send_keys('operadriver\n')

time.sleep(5) #see the result
driver.quit()

编辑：
查看硒的更改日志，似乎在2.45之后不再支持基于Presto的Operas，这就是为什么您收到错误消息的原因：CHANGELOG
