SessionNotCreatedException:此版本的ChromeDriver仅支持使用ChromeDriver的Chrome 84版本以及通过Selenium和Python的Chrome [英] SessionNotCreatedException: This version of ChromeDriver only supports Chrome version 84 using ChromeDriver and Chrome through Selenium and Python

问题描述

我在Windows 7，Selenium，ChromeDriver 84版上使用python 3 (最新)来自动执行我的Chrome浏览器.

I am using python 3 on windows 7, selenium, chromedriver version 84 (latest) to automate my chrome browser.

我正在使用此脚本:

from selenium import webdriver
#import chromedriver_binary  # Adds chromedriver binary to path

driver = webdriver.Chrome()
driver.get("http://www.python.org")

我总是在运行它时收到此错误.

and I always get this error upon running it.

Traceback (most recent call last):
  File "D:\Huzefa\Desktop\zzzzzz.py", line 4, in <module>
    driver = webdriver.Chrome()

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 84

我的ChromeDriver在路径中.另外，我还使用了其他版本的chromedriver，但我无法导航到网站！

My ChromeDriver is in path. Also i have used other versions of chromedriver but i am not able to navigate to a website!

推荐答案

此错误消息...

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 84

...表示 ChromeDriver 无法启动/产生新的浏览上下文，即 Chrome浏览器会话.

...implies that the ChromeDriver was unable to initiate/spawn a new Browsing Context i.e. Chrome Browser session.

您的主要问题是所使用的二进制文件版本之间的不兼容性:

Your main issue is the incompatibility between the version of the binaries you are using as follows:

• 您正在使用 chromedriver = 84
• chromedriver = 84 的发行说明明确提到:

• You are using chromedriver=84
• Release Notes of chromedriver=84 clearly mentions:

支持 Chrome 84版本

• 大概您使用的是Chrome最新推送 chrome = 83 .
• Presumably you are using chrome=83 the latest push for Chrome.

因此 ChromeDriver v84 与 Chrome浏览器v83

有两个(2)解决方案.

There are two (2) solutions to this issue.

• 最简单的解决方案是下载并开始使用> > chromedriver = 83.0.4103.39
• 如果要继续使用 chromedriver = 84 ，则必须从以下两个官方开发存储库中下载最新的 Chromium 二进制文件:
  • 铬项目
  • chromium.appspot
  • Chrome Canary-每晚为开发人员构建
  • The easiest solution would be to download and start using chromedriver=83.0.4103.39
  • If you want to continue with chromedriver=84 you have to download the latest Chromium binary from either of the official development repositories:
    • The Chromium Projects
    • chromium.appspot
    • Chrome Canary - Nightly build for developers

    另外还要确保:

    • 硒已升级到当前级别版本3.141.59 .
    • 如果您的基本 Web客户端版本太旧，则将其卸载并安装最新版本的 Web客户端 GA.
    通过 IDE
    • 清理您的项目工作区和重建您的项目，并且仅具有必需的依赖项.
    • 如果您的基本 Web客户端版本太旧，则将其卸载并安装最新版本的 Web客户端 GA.
    • 进行系统重启.
    • 以非root用户用户的身份执行@Test.
    • 始终在tearDown(){}方法中调用driver.quit()以关闭&优雅地销毁 WebDriver 和 Web Client 实例.
    • Selenium is upgraded to current levels Version 3.141.59.
    • If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
    • Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
    • If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
    • Take a System Reboot.
    • Execute your @Test as non-root user.
    • Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
