从此告别手动下载selenium驱动，自动跟随浏览器（Chrom，）更新驱动

webdriver-manager

它可以自动帮你识别当前运行环境下系统信息以及对应浏览器信息，并自动下载对应的webdriver，再也不用担心webdriver版本问题！！！

1. Pycharm安装或者CMD界面直接PIP下载
   pip install webdriver-manager

2. Chrome用法

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service
 
service = Service(executable_path=ChromeDriverManager().install())
options = webdriver.ChromeOptions()
driver = webdriver.Chrome(service=service, options=options)
driver.get("http://app.nsyw.run/")

3. Firefox用法

from selenium import webdriver
from webdriver_manager.firefox import GeckoDriverManager
 
driver = webdriver.Firefox(executable_path=GeckoDriverManager().install())
driver.get("http://app.nsyw.run/")

4. IE用法

from selenium import webdriver
from webdriver_manager.microsoft import IEDriverManager
 
driver = webdriver.Ie(IEDriverManager().install())
driver.get("http://app.nsyw.run/")

5. Edge用法

from selenium import webdriver
from webdriver_manager.microsoft import EdgeChromiumDriverManager
 
driver = webdriver.Edge(EdgeChromiumDriverManager().install())
driver.get("http://app.nsyw.run/")

6. Opera用法

from selenium import webdriver
from webdriver_manager.opera import OperaDriverManager
 
driver = webdriver.Opera(executable_path=OperaDriverManager().install())
driver.get("http://app.nsyw.run/")
