使用 Selenium 后，我决定尝试 undetected-chromedriver ，因此我使用

 pip install undetected-chromedriver

但是，运行这个简单的脚本

import undetected_chromedriver.v2 as uc

options = uc.ChromeOptions()
options.add_argument('--no-sandbox')

driver = uc.Chrome(options=options)
with driver:
    driver.get('https://google.com') 

会出现错误

selenium.common.exceptions.WebDriverException: Message: unknown error: cannot connect to chrome at 127.0.0.1:37541 from chrome not reachable

使用常规 Selenium 没有问题

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument('--headless')
options.add_argument("--no-sandbox"); # Bypass OS security model

driver = webdriver.Chrome(options=options)
with driver:
    driver.get('https://google.com') 

这是回溯

有什么建议吗？

尝试 #1

还尝试将 executable_path 设置为 /usr/bin/chromedriver

import undetected_chromedriver.v2 as uc

options = uc.ChromeOptions()
options.add_argument('--no-first-run --no-service-autorun --password-store=basic')

CHROME_DRIVER_PATH = '/usr/bin/chromedriver'
driver = uc.Chrome(executable_path=CHROME_DRIVER_PATH, options=options)
with driver:
    driver.get('https://google.com') 

结果相同错误

selenium.common.exceptions.WebDriverException: Message: unknown error: cannot connect to chrome at 127.0.0.1:42305 from chrome not reachable

检查路径是否存在

# ll /usr/bin/chromedriver
-rwxr-xr-x 1 root root 8298464 Oct  1 14:19 /usr/bin/chromedriver*

尝试 #2

尝试使用 Xvfb 并禁用无头模式

import undetected_chromedriver.v2 as uc
from xvfbwrapper import Xvfb
vdisplay = Xvfb(width=800, height=1280)
vdisplay.start()

options = uc.ChromeOptions()
options.add_argument('--no-first-run --no-service-autorun --password-store=basic')
options.user_data_dir = f'./tmp/test_undetected_chromedriver'
options.add_argument(f'--disable-gpu')
options.add_argument(f'--no-sandbox')
options.add_argument(f'--disable-dev-shm-usage')

CHROME_DRIVER_PATH = '/usr/bin/chromedriver'
driver = uc.Chrome(executable_path=CHROME_DRIVER_PATH, options=options, headless=False)
with driver:
    driver.get('https://google.com') 
    print(driver.title)

略有不同的错误
