python - Python Selenium Chrome Webdriver 未安装

问题描述

我正在尝试自动安装最新版本的 Chrome 驱动程序，然后将其用于我的脚本，但遇到了错误。关于这里有什么问题的任何想法？我的缓存有什么东西吗？

driver2 = webdriver.Chrome(ChromeDriverManager().install())
options = selenium.webdriver.ChromeOptions()
#options.add_argument('headless')
options.add_argument('window-size=1920x1080')
driver = webdriver.Chrome(driver2, options=options)

错误：

[WDM] - Looking for [chromedriver 89.0.4389.23 win32] driver in cache 
[WDM] - File found in cache by path [C:\Users\xxx\.wdm\drivers\chromedriver\89.0.4389.23\win32\chromedriver.exe]

解决方案

你需要告诉webdriver的路径：

webdriver.chrome(executable_path=*path*,options=options)

但 driver2 = webdriver.Chrome(ChromeDriverManager().install()) 创建一个新的硒实例。

driver = webdriver.Chrome(ChromeDriverManager().install(),options=options)

应该适用于您的用例 - 您的代码的第一行不是必需的。

请注意，“无头”也需要在它前面加上“--”。

完整代码：

options = selenium.webdriver.ChromeOptions()
#options.add_argument('--headless')
#could also do options.headless = True
options.add_argument('--window-size=1920x1080')
driver = webdriver.Chrome(ChromeDriverManager().install(), options=options)
driver.get('enterwebsite.ext')
#do other stuff
