WebDriverException：消息：未知错误：Chrome 无法启动：崩溃

Question

我正在尝试使用headless chromewith selenium，我为 chromedriver 的路径创建了一个符号链接到 /usr/local/bin 中，但是当我运行时

from selenium import webdriver

options = webdriver.ChromeOptions()    
options.add_argument('--headless')

browser = webdriver.Chrome()
browser.get('http://www.google.com')

我得到的错误是

     Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/anaconda2/envs/tensorflow/lib/python2.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 69, in __init__

它还生成一个 core.*****，一个带有五个随机数的核心文件点，大小超过 200MB。

版本：

Selenium 3.0.0b3 
Google Chrome 60.0.3112.113  
chromedriver 2.30

谁能帮我找出问题所在吗？

当您尝试在无头模式下打开 Chrome 浏览器时，您无需创建任何额外的设置或符号链接。保存/存储chromedriver系统上的任何位置并通过其绝对路径访问该位置。要包含参数，--headless您需要借助Options类并在初始化对象时传递对象，webdriver如下所示：

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

options = Options()
options.add_argument("start-maximized")
options.add_argument("disable-infobars")
options.add_argument("--disable-extensions")
options.add_argument('--headless')
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get('https://www.google.co.in')
print("Page Title is : %s" %driver.title)
driver.quit()

控制台输出：

Page Title is : Google
