selenium.common.exceptions.WebDriverException：消息：服务 chromedriver 意外退出。 状态码是：1

Question

I'm new to Python programming, currently learning Selenium so please excuse what may very well be a beginner level question.

I installed Selenium using Homebrew, then i tried to execute this on my terminal.

from selenium import webdriver 
webdriver.Chrome()

And then i get this error message.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/selenium/webdriver/chrome/webdriver.py", line 73, in __init__
    self.service.start()
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/selenium/webdriver/common/service.py", line 98, in start
    self.assert_process_still_running()
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/selenium/webdriver/common/service.py", line 109, in assert_process_still_running
    raise WebDriverException(
selenium.common.exceptions.WebDriverException: Message: Service chromedriver unexpectedly exited. Status code was: 1

I found similar error messages but with a different status code so i can't find a way to solve this be it in the documentation or on StackOverflow.

The problem is that you're missing ChromeDriver,

First, find which version of Chrome are you using:

• Click on the three dots on the top right corner (in Chrome)
• Help
• About Google Chrome

Second, find and download the right version of ChromeDriver

• https://chromedriver.chromium.org/downloads

Third, Unzip the package and move it to the usr/local/bin folder.

( usr/local/bin path worked for me on macOS, might be different for different OS)
