解决 super(WebDriver, self).__init__(DesiredCapabilities.CHROME[‘browserName‘], “goog“,.....问题

运行selesium代码

出现下面bug详细信息如下：

PS C:\Users\16179> & D:/Work/Python/Python310/python.exe e:/Work/vscode/Untitled-1.py

selenium.common.exceptions.WebDriverException: Message: unknown error: cannot find Chrome binary
  (Driver info: chromedriver=2.9.248315,platform=Windows NT 6.3 x86_64)

解决方法

如下

1.先打开chrome 输入 “chrome://version/”来查看chrome版本 如图我的是97

2.然后访问此网站
http://chromedriver.storage.谷歌apis.com/index.html

然后选择合适版本的driver

我这边是windows版本的系统所以下载 win32版本的压缩包

解压后里面是个这个东西

3. 把解压后的 chromedriver.exe 文件放入 python 替换现有的chromedriver.exe

4. 之后再运行代码问题解决了
