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

Process finished with exit code 1

根据错误提示：Message: 'chromedriver' executable needs to be in PATH我们可以找到原因所在：chromedriver需要放在python安装路径下。

所以要把chromedriver放到python安装路径下就可以了，不要放到chrome安装目录下，没有起作用

可以从下面下载chromedriver，不同chrome版本，要下载不同chromedriver的版本，要注意对应呀

引用的chorme版本：

# Chrome/81.0.4044.20 就是引用的chorme版本，挑选对应的，也可以自己改
headers = {
            'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.20 Safari/537.36',
        }

下面是chromedriver下载的路径，请放心下载使用

http://chromedriver.storage.googleapis.com/index.html
