'selenium.common.exceptions.WebDriverException:消息:u'chrome无法访问

Question

我正在使用webdriver来配置路由器,但是当我运行脚本时:

from selenium import webdriver
self.driver = webdriver.Chrome()

它打开chrome并且没有响应,然后引发异常:

铬无法到达.

我的电脑有两张网卡,当我禁用一张网卡时,效果很好.
我不知道为什么,请帮忙!

在纯粹的情况下,"chrome notachable"意味着可以启动Chrome二进制文件,但无法访问调试端口.

调试端口由参数设置: - remote-debugging-port = 12582

在我的情况下,它发生是因为沙盒的一些问题:

ps afvvx | grep chrome

/opt/google/chrome/chrome --disable-background-networking --disable-client-side-phishing
21026 pts/2    S+     0:00      0    47  6008   100  0.0  |           \_ cat
21027 pts/2    S+     0:00      0    47  6008   100  0.0  |           \_ cat

当我运行/ opt/google/chrome/chrome-sandbox时

# /opt/google/chrome/chrome-sandbox  -h
The setuid sandbox provides API version 1, but you need 0

从上面的url我无法得到我将要做的修复SUID SandBox,但它可以通过Chrome arg --disable-setuid-sandbox(有时使用--no-sandbox)关闭:

import time
from selenium import webdriver

from xvfbwrapper import Xvfb

vdisplay = Xvfb()
vdisplay.start()

from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument("--disable-setuid-sandbox")

driver = webdriver.Chrome('/usr/local/sbin/chromedriver', chrome_options=chrome_options)  # Optional argument, if not specified will search path.
driver.get('http://www.google.com/xhtml');
time.sleep(5) # Let the user actually see something!
search_box = driver.find_element_by_name('q')
search_box.send_keys('ChromeDriver')
search_box.submit()
time.sleep(5) # Let the user actually see something!
driver.quit()

vdisplay.stop()
