问题描述

我尝试在 debian 服务器 8.11 上运行 selenium webdriver 并收到错误.

i try to run the selenium webdriver on a debian server 8.11 and get an error.

Java:java 版本1.7.0_221"，OpenJDK 运行时环境(IcedTea 2.6.18)

Java: java version "1.7.0_221", OpenJDK Runtime Environment (IcedTea 2.6.18)

网络驱动程序:ChromeDriver (v2.9.248304)

Webdriver: ChromeDriver (v2.9.248304)

源码:

from selenium import webdriver
from pyvirtualdisplay import Display

display = Display(visible=0, size=(800, 800))
display.start()
co = webdriver.ChromeOptions()
co.add_argument("--user-data-dir=profile")
browser = webdriver.Chrome('/usr/local/bin/chromedriver', options=co)
browser.get('example.com')
browser.quit()
display.close()

我收到此错误:

Traceback (most recent call last):

    browser = webdriver.Chrome('/usr/local/bin/chromedriver', options=co)

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally
  (Driver info: chromedriver=2.9.248304,platform=Linux 4.9.0-0.bpo.9-amd64 x86_64)

我尝试了几种解决方案，但没有任何效果...

I try several solutions but nothing works...

推荐答案

这个错误信息...

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally
  (Driver info: chromedriver=2.9.248304,platform=Linux 4.9.0-0.bpo.9-amd64 x86_64)

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

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

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:

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

• 您正在使用 chromedriver=2.9
• chromedriver=2.9 的发行说明明确提及以下内容:

支持 Chrome v31-34

• 大概你正在使用 chrome= 76.0
• ChromeDriver v76.0的发行说明/a> 明确提及以下内容:
• Presumably you are using chrome= 76.0
• Release Notes of ChromeDriver v76.0 clearly mentions the following :

支持Chrome 76版

• 您的 Selenium 客户端 版本对我们来说是未知.
• 您提到JDK 版本 是1.7.0_221，相当古老.
• Your Selenium Client version is unknown to us.
• You mentioned about JDK version is 1.7.0_221 which is pretty ancient.

所以 ChromeDriver v2.9 和 Chrome 浏览器 v76.0

确保:

• Selenium 已升级到当前级别版本 3.141.59.
• ChromeDriver 已更新为当前 ChromeDriver v76.0 级别.
• Chrome 已更新至当前 Chrome 版本 76.0 级别.(根据 ChromeDriver v76.0 发行说明)
• 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.
• 如果您的基础 Web Client 版本太旧，请通过 卸载它Revo Uninstaller 并安装最新的 GA 和发布版本的 Web Client.
• 进行一次系统重启.
• 以 非 root 用户身份执行您的 @Test.
• 总是在 tearDown(){} 方法中调用 driver.quit() 来关闭 &优雅地销毁 WebDriver 和 Web Client 实例.
• Selenium is upgraded to current levels Version 3.141.59.
• ChromeDriver is updated to current ChromeDriver v76.0 level.
• Chrome is updated to current Chrome Version 76.0 level. (as per ChromeDriver v76.0 release notes)
• 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 through Revo Uninstaller 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.
