消息：未知错误：Chrome 无法启动：在带有 Linux 4.9.85-38.58.amzn1.x86_64 x86_64 的 AWS Cloud9 上异常退出

Question

在 AWS Cloud9 中工作，我的脚本是：

from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
import requests


options = Options()
options.binary_location = '/usr/bin/google-chrome'
driver = webdriver.Chrome(chrome_options=options, executable_path='/home/ec2-user/environment/downloads/chromedriver')
url = 'http://google.com'
driver.get(url)

soup = BeautifulSoup(driver.page_source, 'lxml')

# driver.quit()    

print(soup)

但是，当我运行文件时，运行配置会挂起，直到我用 ctrl+c 键盘中断。 Traceback 会返回这个：

刚刚花了 4 个小时尝试将 chrome 和 beautifulsoup 安装到 AWS Cloud 9 上。非常困难。

编辑：我只是让它运行直到它自行停止并返回Message: unknown error: Chrome failed to start: exited abnormally

编辑 2：驱动程序信息：chromedriver=2.10.267518，

平台=Linux 4.9.85-38.58.amzn1.x86_64 x86_64

谷歌浏览器 66.0.3359.117

Answer 1

此错误消息...

Message: unknown error: Chrome failed to start: exited abnormally

...暗示 ChromeDriver 无法建立新的 Chrome 会话。

根据您的问题更新，您的主要问题是您使用的二进制文件之间的版本兼容性，如下所示：

• 您正在使用 chromedriver=2.10，它非常 old 和 ancient
• 您正在使用 chrome=66.0
• ChromeDriver v2.38 的发行说明明确提及以下内容：

支持 Chrome v65-67

• 我们不知道您的 Selenium 客户端 版本。

所以 ChromeDriver 版本 (v2.10) 和 Chrome 浏览器 版本 (v66. 0)

解决方案

• 将Selenium升级到当前级别Version 3.11.0。
• 将 ChromeDriver 升级到当前的ChromeDriver v2.38 级别。
• 将 Chrome 版本保持在 Chrome v66.x 级别。 (as per ChromeDriver v2.38 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。
• 使用CCleaner 工具在执行测试套件之前和之后清除所有操作系统杂务。
• 如果您的基础 Web Client 版本太旧，请通过 Revo Uninstaller 卸载它并安装最新的 GA 和发布版本的 Web Client。
• 进行系统重启。
• 执行您的@Test。
