Python Selenium Chrome Webdriver未安装

Question

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。有什么想法是不是出了什么问题？我的缓存有问题吗？

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]

Answer 1

您需要告诉webdriver的路径：

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

但是driver2 = webdriver.Chrome(ChromeDriverManager().install())创建了一个新的selenium实例。

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

应该和你的用例一起工作--代码的第一行是不必要的。

请注意，“无头”也需要“--”在它前面。

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

Answer 2

driver = webdriver.Chrome(driver2, options=options)

您将发送一个WebDriver对象作为位置参数。

https://www.selenium.dev/selenium/docs/api/py/webdriver_chrome/selenium.webdriver.chrome.webdriver.html#module-selenium.webdriver.chrome.webdriver

WebDriver的第一个参数是可执行文件路径。

Answer 3

试一试：

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from webdriver_manager.chrome import ChromeDriverManager

options = Options()
options.add_argument('--headless')
options.add_argument('--window-size=1920,1080')
driver = webdriver.Chrome(ChromeDriverManager().install(), options=options)

driver.get('https://google.com')

driver.quit()

当你将参数选项传递给webdriver时，将其设置在初始化之上，并将其放入chrome()中，如下所示：

options = Options()
options.add_argument('--headless')
options.add_argument('--window-size=1920,1080')
driver = webdriver.Chrome(ChromeDriverManager().install(), options=options)

并最终初始化驱动程序
