selenium.common.exceptions.WebDriverException: Message: Service

问题

I had a trouble when i use selenium to control my Chrome. Here is my code:

from selenium import webdriver
driver = webdriver.Chrome()

When i tried to operate it ,it runs successfully at first,the Chrome pop on the screen. However, it shut down at the few seconds.

Traceback (most recent call last):
  File "<pyshell#3>", line 1, in <module>
    driver = webdriver.Chrome('C:\Program Files (x86)\Google\Chrome\chrome.exe')
  File "C:\Users\35273\AppData\Local\Programs\Python\Python35\lib\site-packages\selenium\webdriver\chrome\webdriver.py", line 62, in __init__
    self.service.start()

    self.assert_process_still_running()
  File "C:\Users\35273\AppData\Local\Programs\Python\Python35\lib\site-packages\selenium\webdriver\common\service.py", line 99, in assert_process_still_running
    % (self.path, return_code)

回答1:

You need to provide the path of chromedriver...download from http://chromedriver.storage.googleapis.com/index.html?path=2.24/...unzip it and provide path to it in... webdriver.chrome ("path to chromedriver")

I explain the things here:

from selenium import webdriver


driver = webdriver.Chrome("C:\Program Files (x86)\Google\Chrome\Application\chrome.exe")

This is the error if i run the above code:

    C:\Python27\python.exe C:/Users/Gaurav.Gaurav-PC/PycharmProjects/Learning/StackOverflow/SeleniumQuestion/test123.py
    Traceback (most recent call last):
      File "C:/Users/Gaurav.Gaurav-PC/PycharmProjects/Learning/StackOverflow/SeleniumQuestion/test123.py", line 4, in <module>
        driver = webdriver.Chrome("C:\Program Files (x86)\Google\Chrome\Application\chrome.exe")
      File "C:\Python27\lib\site-packages\selenium\webdriver\chrome\webdriver.py", line 62, in __init__
        self.service.start()
      File "C:\Python27\lib\site-packages\selenium\webdriver\common\service.py", line 86, in start
        self.assert_process_still_running()
      File "C:\Python27\lib\site-packages\selenium\webdriver\common\service.py", line 99, in assert_process_still_running
        % (self.path, return_code)
    selenium.common.exceptions.WebDriverException: Message: Service C:\Program Files (x86)\Google

\Chrome\Application\chrome.exe unexpectedly exited. Status code was: 0

Which is same as mentioned by @Weiziyoung in original problem.

The solution is as I mentioned you need to provide the path to chromedriver in place of chrome browser like

driver = webdriver.Chrome("E:\Jars\chromedriver.exe")

It will resolve the problem
