lunix中啓動webdriver時報錯一：

測試代碼爲：

1. #!/usr/bin/python

2. # -*- coding: utf-8 -*-

3.  
4.  

5. from selenium import webdriver

6.  

7. driver = webdriver.Firefox()

8. driver.get("https://www.baidu.com")

運行報錯信息以下：

1. Traceback (most recent call last):

2. File "maimai_web.py", line 14, in <module>

3. driver = webdriver.Firefox()

4. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/firefox/webdriver.py", line 152, in __init__

5. keep_alive=True)

6. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 98, in __init__

7. self.start_session(desired_capabilities, browser_profile)

8. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 188, in start_session

9. response = self.execute(Command.NEW_SESSION, parameters)

10. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 256, in execute

11. self.error_handler.check_response(response)

12. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/errorhandler.py", line 194, in check_response

13. raise exception_class(message, screen, stacktrace)

14. selenium.common.exceptions.WebDriverException: Message: Process unexpectedly closed with status 1

處理方法：

1. #!/usr/bin/python

2. # -*- coding: utf-8 -*-

3.  
4.  

5. from pyvirtualdisplay import Display

6. from selenium import webdriver

7.  
8.  

9. display = Display(visible=0, size=(1920, 1080))

10. display.start()

11. driver = webdriver.Firefox()

12. driver.get("https://www.baidu.com")

結果：

運行ok，搞定！

坑2、webdriver實例化報錯

採用多線程調用webdriver時候，偶爾會出現這樣的錯：selenium.common.exceptions.WebDriverException: Message: connection refused

1. Exception in thread Thread-2:

2. Traceback (most recent call last):

3. File "/usr/local/python3.6/lib/python3.6/threading.py", line 916, in _bootstrap_inner

4. self.run()

5. File "/usr/local/python3.6/lib/python3.6/threading.py", line 864, in run

6. self._target(*self._args, **self._kwargs)

7. File "maimai_tran_account_driver.py", line 591, in debug

8. t = TrainAccount(count,lock)

9. File "maimai_tran_account_driver.py", line 32, in __init__

10. self.chrome = webdriver.Firefox()

11. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/firefox/webdriver.py", line 152, in __init__

12. keep_alive=True)

13. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 98, in __init__

14. self.start_session(desired_capabilities, browser_profile)

15. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 188, in start_session

16. response = self.execute(Command.NEW_SESSION, parameters)

17. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 256, in execute

18. self.error_handler.check_response(response)

19. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/errorhandler.py", line 194, in check_response

20. raise exception_class(message, screen, stacktrace)

21. selenium.common.exceptions.WebDriverException: Message: connection refused
