title: Python selenium driver.get error
body: <p>I've used selenium to crawl data for around nine months.The code below ran normally last week.</p>
  
  <pre><code>import os
  from selenium import webdriver
  chromedriver = 'the path of the driver.exe'
  os.enviorn["webdriver.chrome.driver"] = chromedriver
  browser = webdriver.Chrome(chromedriver)
  browser.get(url)
  </code></pre>
  
  <p>However, as I tried to run the same code this week, I got the this error.</p>
  
  <pre><code>Traceback (most recent call last):
    File "&lt;pyshell#5&gt;", line1, in &lt;module&gt;
      browser.get(url)
    File "C:\Python27\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 213, in get 
      self.execute(Command.GET, {'url':url})
    File C:\Python27\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 201, in execute
      self.error_handler.check_response(response)
    File C:\Python27\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 188, in check_response 
      raise.exception_class(message, screen, stacktrace)
  WebDriverException: Message:
  </code></pre>
  
  <p>I changed different url and the error message remains the same. In addition, after trying twice the browser.get function, the chrome driver will crash.</p>
  
  <p>Really have no idea what is wrong or what can I do instead?</p>
