1、查看安装的chrome浏览器版本
2、查看版本对应的驱动
https://sites.google.com/a/chromium.org/chromedriver/downloads
下载后拷贝到/usr/local/bin/目录下
结果在运行程序的时候右报错:selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH
后来网上查下修改如下代码:
chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--disable-gpu')
self.driver = webdriver.Chrome(chrome_options=chrome_options)
就正常运行了
