解决selenium.common.exceptions.SessionNotCreatedException:ChromeDriver only supports Chrome version 77

环境

• Ubuntu 16.04 LTS
• python 3.x

报错信息：

使用 Chrome 浏览器运行Web自动化测试报错，信息如下：

Traceback (most recent call last):

    click_web(main_page_url)
  File "click_csdn_chromedriver.py", line 13, in click_web

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 77

原因

chrome和chromedriver版本不匹配

解决方法

• 1、在chrome浏览器地址里面输入：chrome://version/，查看浏览器版本
  

• 2、找对应的chromedriver版本

  chromedriver下载地址：http://chromedriver.storage.googleapis.com/index.html
  对应我的chrome版本，我下载的是：
  

• 3、 解压
  unzip chromedriver_linux64.zip

• 4、mv到/usr/local/bin/下

  sudo mv chromedriver /usr/local/bin/

• 5、查看版本

  chromedriver -v

  ChromeDriver 80.0.3987.16 (320f6526c1632ad4f205ebce69b99a062ed78647-refs/branch-heads/3987@{#185})
  

• 6、再次运行程序，一切ok！
