Python Selenium Chrome Webdriver 未安装

Question

I am trying to automatically install the latest version of Chrome Driver and then use that for my script, but am running into errors. Any thoughts as to what's wrong here? Something with my cache?

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)

Error:

[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

You need to tell the path of the webdriver:

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

but driver2 = webdriver.Chrome(ChromeDriverManager().install()) creates a new instance of selenium.

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

should work with your use case - the 1st line of your code is not necessary .

Please note that the 'headless' needs '--' in front of it, too.

Full code:

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)

You're sending a WebDriver object as a positional argument.

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

The first argument to WebDriver is the executable path.

Answer 3

try that out:

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()

when you're passing argument options to webdriver, set it above initializing and put it in chrome() like that:

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

and initialize driver finally
