urllib3.exceptions.ProtocolError: ('Connection aborted.', error(10054, '现有连接被远程主机强行关闭'))

Question

我正在尝试使用 Python Selenium chromedriver 在 chrome 上打开一个网站。 Chrome 浏览器正在打开（带有警告）并且 url 没有打开。

版本详情：Chrome：68.0.3440.106 硒：3.14.0 铬驱动程序：2.20 蟒蛇：2.7

我正在使用以下代码：

import time
from selenium import webdriver
import selenium
driver = webdriver.Chrome("C:/Python27/chromedriver.exe")
driver.get("https://vancouver.craigslist.ca/")
print(driver.title)
time.sleep(8)
driver.quit()

我遇到以下错误：

此错误消息...

urllib3.exceptions.ProtocolError: ('Connection aborted.', error(10054, 'An existing connection was forcibly closed by the remote host'))

...暗示 ChromeDriver 无法启动/生成新的 WebBrowser 即 Chrome 浏览器 会话。

您的主要问题是您使用的二进制文件版本之间的不兼容性，如下所示：

• 您正在使用 chromedriver=2.20
• chromedriver=2.20 的发行说明明确提及以下内容：

支持 Chrome v43-48

• 您正在使用 chrome=68.0
• ChromeDriver v2.41 的发行说明明确提及以下内容：

支持 Chrome v67-69

所以 ChromeDriver v2.33 和 Chrome 浏览器 v65.0

之间存在明显的不匹配

解决方案

• 将 ChromeDriver 升级到当前的ChromeDriver v2.41 级别。
• 将 Chrome 版本保持在 Chrome v67-69 级别之间。 (as per ChromeDriver v2.41 release notes)
• 清理你的项目工作区通过你的IDE和重建你的项目只需要依赖。
• 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。
• 执行您的@Test。
