代码如下：

from selenium import webdriver
b = webdriver.Chrome()
b.get('http://192.168.100.21:9199/scyx')
b.maximize_window()

Exception ignored in: <bound method Service.__del__ of <selenium.webdriver.chrome.service.Service object at 0x015FA530>>
Traceback (most recent call last):
  File "C:\Python\Python36-32\lib\site-packages\selenium\webdriver\common\service.py", line 173, in __del__
  File "C:\Python\Python36-32\lib\site-packages\selenium\webdriver\common\service.py", line 149, in stop
  File "C:\Python\Python36-32\lib\site-packages\selenium\webdriver\common\service.py", line 120, in send_remote_shutdown_command

ImportError: sys.meta_path is None, Python is likely shutting down

解决方案：

在下面增加quit()

from selenium import webdriver
b = webdriver.Chrome()
b.get('http://192.168.100.21:9199/scyx')
b.maximize_window()
b.quit()
