Selenium + Python：空输出[重复]

Question

我为 3 和 2.7 都安装了 selenium python 我运行以下脚本：

1) vi test.py:

from selenium import webdriver
import time


chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
driver = webdriver.Chrome('/usr/bin/chromedriver',chrome_options=chrome_options)

driver.get('https://python.org')

我从输出中一无所获。如果我删除参数并保持基本：

2) vi new.py:

from selenium import webdriver
import time


chrome_options = webdriver.ChromeOptions()
driver = webdriver.Chrome('/usr/bin/chromedriver',chrome_options=chrome_options)

element = driver.get('https://python.org')

我收到以下错误：

Traceback (most recent call last):
  File "new.py", line 8, in <module>
    driver = webdriver.Chrome('/usr/bin/chromedriver',chrome_options=chrome_options)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/chrome/webdriver.py", line 81, in __init__

    response = self.execute(Command.NEW_SESSION, parameters)

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally
  (unknown error: DevToolsActivePort file doesn't exist)
  (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
  (Driver info: chromedriver=2.41.578700 (2f1ed5f9343c13f73144538f15c00b370eda6706),platform=Linux 4.18.0-10-generic x86_64)

我安装了： 快速安装铬 sudo apt-get install chromium-browser chromium-chromedriver 点安装硒

Answer 1

1. 在无头模式下看不到驱动程序（自动浏览器）是正常的。
2. 尝试安装 Chrome 浏览器（您的第二个脚本）：

wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
sudo dpkg -i google-chrome-stable_current_amd64.deb

希望对你有帮助！
