Question

这是一个MCVE：

/.travis.yml：

language: python
python:
  - "3.5"
dist: trusty
addons:
  chrome: stable
before_install:
  - pip install selenium
  - wget https://chromedriver.storage.googleapis.com/2.35/chromedriver_linux64.zip
  - unzip chromedriver_linux64.zip -d test/driver/
before_script:
  - "export DISPLAY=:99.0"
  - "sh -e /etc/init.d/xvfb start"
  - sleep 3
script:
  - cd test
  - python3 ./test_main.py

/test/test_main.py：

from selenium.webdriver import *
b=Chrome('driver/chromedriver')
b.get('http://example.com')
b.quit()

构建将失败，引发一个例外，说铬崩溃了：

$ python3 ./test_main.py
Traceback (most recent call last):
  File "./test_main.py", line 2, in <module>
    b=Chrome('driver/chromedriver')
  File "/home/travis/virtualenv/python3.5.4/lib/python3.5/site-packages/selenium/webdriver/chrome/webdriver.py", line 75, in __init__
    desired_capabilities=desired_capabilities)
  File "/home/travis/virtualenv/python3.5.4/lib/python3.5/site-packages/selenium/webdriver/remote/webdriver.py", line 154, in __init__
    self.start_session(desired_capabilities, browser_profile)
  File "/home/travis/virtualenv/python3.5.4/lib/python3.5/site-packages/selenium/webdriver/remote/webdriver.py", line 243, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "/home/travis/virtualenv/python3.5.4/lib/python3.5/site-packages/selenium/webdriver/remote/webdriver.py", line 312, in execute
    self.error_handler.check_response(response)
  File "/home/travis/virtualenv/python3.5.4/lib/python3.5/site-packages/selenium/webdriver/remote/errorhandler.py", line 237, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: crashed
  (Driver info: chromedriver=2.35.528139 (47ead77cb35ad2a9a83248b292151462a66cd881),platform=Linux 4.14.12-041412-generic x86_64)

上面的代码几天前就已经运行了，所以我想知道它是否是travis构建环境中的一个bug。

根据支持团队的说法：

我们在基于容器的基础架构上安装的Chrome版本似乎发生了变化。我们仍然在研究促成因素，我们很快就会提出解决方案。

与此同时，解决方法是通过在.travis.yml文件中添加以下内容，将构建路由到支持sudo的基础架构：
sudo: required
addons:
  chrome: stable

Chromedriver在Travis CI坠毁
