SessionNotCreatedException:消息：会话未创建：此版本的ChromeDriver仅支持使用ChromeDriver和Chrome的Chrome版本87

Question

我正在尝试让selenium打开一个站点，我的PyCharm编辑器中没有任何错误，但是当我运行代码时，我遇到了很多错误，我不太明白，如果能得到一些帮助会很好

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Chrome(executable_path=r"C:\chromedriver\chromedriver.exe")

driver.get("https://www.singaporetech.edu.sg/")  # get gets url
print(driver.title)  # title of the page

driver.close()

这是我得到的错误：

C:\Users\kaush\PycharmProjects\seleniumTest1\venv\Scripts\python.exe C:/Users/kaush/PycharmProjects/seleniumTest1/main.py

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 87
Current browser version is 86.0.4240.198 with binary path C:\Program Files (x86)\Google\Chrome\Application\chrome.exe

Answer 1

此错误消息

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 87
    Current browser version is 86.0.4240.198 with binary path C:\Program Files (x86)\Google\Chrome\Application\chrome.exe

…意味着ChromeDriver无法启动/生成新的浏览上下文，即Chrome浏览器会话

您的主要问题是所使用的二进制文件版本之间的不兼容，如下所示：

• 您使用的是chromedriver=87.0
• chromedriver=87.0的发行说明明确提到以下内容：

Supports Chrome version 87

• 您正在使用Chromev86.0.4240.198

因此，ChromeDriver v2.40和Chrome浏览器v85.0之间存在明显的不匹配

---

解决方案

确保：

• ChromeDriver更新为当前ChromeDriver v87.0级别
• Chrome更新为当前的Chrome 87.0版本。（根据ChromeDriver v87.0 release notes）
• 如果您的基本Web客户端版本太旧，请卸载它并安装最新的GA和发布版本的Web客户端
• 进行系统重新启动
• 以非root用户身份执行@Test
• 始终在tearDown(){}方法中调用driver.quit()以关闭&；优雅地销毁WebDriver和Web客户端实例
