mac系统chromedriver应该放的位置！usr/local/bin

1. macOS10.14
2. 运行下面这个python时提示： 

   selenium.common.exceptions.WebDriverException: Message: ‘chromedriver’ executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

    

   【from selenium import webdriver
   
   import time
   
   
   url = "https://www.hao123.com/"
   
   driver = webdriver.Chrome()
   
   driver.get(url)
   
   time.sleep(13)】

3. 之前下载的chromedriver放错了位置导致！但是自己又不知道应该放在哪里？于是在网上找到了https://medium.com/@Epicure1709/%E4%BD%BF%E7%94%A8python%E7%9A%84selenium%E6%99%82%E9%81%87%E5%88%B0%E7%9A%84%E4%B8%80%E4%BA%9B%E5%B0%8F%E5%95%8F%E9%A1%8C-7fb5de198ff7重新放置下chromedriver的位置这个再运行代码，正常了！
