centos7 selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH

　　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

　　　3、完整代码
