'selenium.common.exceptions.WebDriverException:消息:u'chrome 无法访问
问题描述
我正在使用 webdriver 来配置路由器，但是当我运行脚本时:
I'm using webdriver to config a router, but when I run script:
from selenium import webdriver
self.driver = webdriver.Chrome()
打开chrome没有反应，然后引发异常:
It opens chrome and no response, and then raise exception:
chrome 无法访问.
chrome not reachable.
我的电脑有两张网卡，当我禁止一个时，它工作得很好.
我不知道为什么，请帮忙！
My computer has two network cards, when I forbbiden one, it works well.
I don't konw why, please help!
解决方案
纯情况下chrome not reachable"表示Chrome二进制可以启动但调试端口不可达.
In pure case "chrome not reachable" means that Chrome binary can be started but debugging port is not reachable.
调试端口由参数设置:--remote-debugging-port=12582
Debugging port is set by argument: --remote-debugging-port=12582
就我而言，这是因为沙盒的一些问题:
In my case it happens because some issues with sand-box:
ps afvvx | grep chrome
/opt/google/chrome/chrome --disable-background-networking --disable-client-side-phishing

当我运行/opt/google/chrome/chrome-sandbox
When I run /opt/google/chrome/chrome-sandbox
# /opt/google/chrome/chrome-sandbox -h
The setuid sandbox provides API version 1, but you need 0

从上面的 url 我无法得到修复 SUID SandBox 的方法，但可以通过 Chrome arg --disable-setuid-sandbox(有时使用 --no-sandbox)将其关闭:
From url above I can't get what I'll to do to fix SUID SandBox, but it can be switched off by Chrome arg --disable-setuid-sandbox(sometimes with --no-sandbox):
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()
