我在 mac os 上使用 python3，我已经将 chrome、chromedriver 和 selenium 更新到最新版本。我遇到了 TimeoutException，浏览器可以正确打开，但它死机了。

>>> from selenium import webdriver
>>> driver = webdriver.Chrome()
# opens browser with blank page
>>> driver.get('http://example.com')
# gets first page OK and then driver literally flashes once
>>> driver.get('http://stackoverflow.com')
>>>
# Cursor loading forever... until TimeoutException

抛出这个错误:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.5/site-packages/selenium/webdriver/remote/webdriver.py", line 248, in get
    self.execute(Command.GET, {'url': url})

    self.error_handler.check_response(response)
  File "/usr/local/lib/python3.5/site-packages/selenium/webdriver/remote/errorhandler.py", line 192, in check_response
    raise exception_class(message, screen, stacktrace)

我正在使用:Python 3.5.2、Chrome 54.0、chromedriver 2.25、selenium 3.0.1

我试过其他版本的 chromedriver 但没有成功，我也没有在网上找到任何解决方案。谢谢。

编辑:

仍然收到上面的错误 + 收到新错误:

最佳答案

selenium.common.exceptions.TimeoutException: Message: timeout: cannot determine loading status from timeout: Timed out receiving message from renderer: -0.003

Issue817:It looks like this issue has been logged as a bug for Selenium .

有人通过使用 chrome 的 --dns-prefetch-disable 选项解决了这个问题。

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

chrome_options = Options()
chrome_options.add_argument('--dns-prefetch-disable')
driver = Chrome(chrome_options=chrome_options)
