自动化测试：Webdriver出错问题

zhangqihong · 2019 年4 月 8 日 03:50

1、我的浏览器是360V10，10.0.1764.0，内核版本是63.0.3239.132
2、我下载的chromedriver.exe，版本号 74.0.3729.6，下载到了pthon37目录下了
3、系统环境window 64位
运行出现如下错误：

请各位指教！

你装chrome浏览器了吗？（需要安装chrome）

zhangqihong · 2019 年4 月 8 日 08:22

我装的是360浏览器，它用的内核也是Chrome的

Arvine · 2019 年4 月 8 日 08:55

似乎你需要这样设置一下?

__browser_url="C:\\Users\\...\\360se.exe"
chrome_options=Options()
chrome_options.binary_location=__browser_url

zhangqihong · 2019 年4 月 8 日 13:52

你说的对，但现在出现了不同的错误提示，应该是浏览器版本与Chrome的版本不同原因，但浏览器360的版本号是63.0.3239.132吗？可没有对应的下载程序啊？

This version of ChromeDriver only supports Chrome version 74

按照错误提示，你应该安装 Chrome 74。

zhangqihong · 2019 年4 月 9 日 13:17

我下载的Chromedriver是74的啊，放在Python37的根目录下了，是不是因为该放在其他地方？还是浏览器版本不配套？

greyli · 2019 年4 月 10 日 02:23

需要搭配对应版本的 Chrome 浏览器使用，而不是 360 浏览器。

zhangqihong · 2019 年4 月 10 日 14:08

是的，改成Chrome浏览器就可以了。但照理说360浏览器也是可以的，就是不知道360浏览器对应的驱动程序是哪个版本。
