使用selenium、webdriver打开谷歌浏览器，登录页面后闪退，但是版本号是对应的，是因为driver的全局变量问题
1、不设置driver为全局，放在函数内（会闪退）
from selenium import webdriver# 登陆百度def main():chromedriver_path = r"C:\Program Files (x86)\Google\Chrome\Application\chromedriver.exe"driver = webdriver.Chrome(executable_path=chromedriver_path)# 打开页面page = driver.get('/')if __name__ == "__main__":main()
2、把driver放在函数外，为全局（不会闪退）
from selenium import webdriverchromedriver_path = r"C:\Program Files (x86)\Google\Chrome\Application\chromedriver.exe"driver = webdriver.Chrome(executable_path=chromedriver_path)# 登陆百度def main():# 打开页面page = driver.get('/')if __name__ == "__main__":main()
3、也可以把driver放在函数内，只要设置为全局变量就可以
from selenium import webdriver# 登陆百度def main():global driverchromedriver_path = r"C:\Program Files (x86)\Google\Chrome\Application\chromedriver.exe"driver = webdriver.Chrome(executable_path=chromedriver_path)# 打开页面page = driver.get('/')if __name__ == "__main__":main()
