WebDriverError错误：Chrome无法启动：退出异常 [英] WebDriverError error: Chrome failed to start: exited abnormally

问题描述

我试图在ubuntu 14.04 vm上运行量角器测试（由google云计算），
出于某种原因，当我运行'量角器conf.js'时出现错误：

E / launcher - WebDriverError：未知错误：Chrome无法启动：异常退出

为了安装无头镀铬：

• 在运行量角器cons.js之前，我正在运行webdriver-manager start / b>当我运行'Xvfb -ac：2 -screen 0 1280x1024x16'时，它冻结时获得
  '初始化内置扩展GLX'




• 我也尝试将conf.js更改为
  chromeOptions：{
  args：[--headless， --disable-gpu，--window-size = 800x600]'
  但量角器打印'开始'然后错误：'失败：未知错误：需要X显示对于键码转换，请考虑使用Xvfb'




• 重要的是要提到它在一两个小时之前都运行良好。
  然后我只是让我的Mac睡觉，当然这是退出vm ..
  

• 我正在同量角器运行相同的测试我的Mac和它的作品很棒。
  问题与实例虚拟机上的chrome / chromeDriver有关。
  

非常感谢!!!

解决方案

在AWS EC2机器中使用selenium + python 2.7 + chromedriver时遇到类似问题。在我的例子中，我使用了最新的无头特征，因此向ChromeOptions对象添加' no-sandbox '参数确实不错。

  chrome_options = webdriver.ChromeOptions（）
 chrome_options.add_argument（'headless'）
 chrome_options.add_argument （'no-sandbox'）
 driver = webdriver.Chrome（chrome_options = chrome_options）
  

这个问题似乎是Chrome的权限问题。它不允许root用户在没有--no-sandbox标志

的情况下执行它

I'm trying to run protractor test on ubuntu 14.04 vm (by google cloud), for some reason when i run 'protractor conf.js' i get an error says:

E/launcher - WebDriverError: unknown error: Chrome failed to start: exited abnormally

I followed this tasks in order to install headless chrome: https://gist.github.com/alonisser/11192482

• Before running protractor cons.js, i'm running "webdriver-manager start"

• When i run 'Xvfb -ac :2 -screen 0 1280x1024x16' its freeze when gets to 'Initializing built-in extension GLX'

• I also tried change the conf.js to chromeOptions: { args: [ "--headless", "--disable-gpu", "--window-size=800x600" ]' but and protractor print 'start' then error: 'Failed: unknown error: an X display is required for keycode conversions, consider using Xvfb'

• It's important to mention that it's all worked great, before a couple hours. then i just let my mac sleep, and of course it was exit the vm..

• I'm running the same tests with protractor in my mac and its works great. the problem is related to chrome/chromeDriver on the instance vm.

thanks a lot!!!

解决方案

I had a similar problem when using selenium + python 2.7 + chromedriver in a AWS EC2 machine.

In my case I was using the newest headless feature, so adding 'no-sandbox' parameter to the ChromeOptions object did the trick.

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('headless')
chrome_options.add_argument('no-sandbox')
driver = webdriver.Chrome(chrome_options=chrome_options)

The problem seems to be a permission issue with chrome. It does not allow a 'root' user to execute it without the --no-sandbox flag
