KeyError： 'google-chrome' - python selenium webdriver AWS EC2

Question

目标

• 不获取错误(两个代码段生成相同的错误)
• 它在aws ec2 ubuntu上运行
• 导入此文件以使用python、selenium、beautifulsoup进行网页抓取，同时持续加载JS网页
• 我遵循这个指南L

我的代码

# selenium 3
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(ChromeDriverManager().install())

# selenium 4
from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install()))

错误

试图通过解决

• 获取KeyError:'；WINDOWSSDKDIR'；在Windows上运行Chromium浏览器源代码时
• https://exerror.com/chromedrivermanager-install-is-giving-keyerror-google-chrome/
• https://github.com/wkeeling/selenium-wire/issues/295

Answer 1

这可能是Selenium 4错误？

试试这个代码看看它是否工作

# selenium 4
from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install()))

Answer 2

Ubuntu 22.04 Chromium Browser安装链接

终端命令：

sudo apt update
sudo apt install chromium-browser

测试

chromium-browser

如何在Ubuntu 20.04&18.04链接

终端命令：

sudo curl -sS -o - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add 
sudo bash -c "echo 'deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main' >> /etc/apt/sources.list.d/google-chrome.list" 
sudo apt -y update 
sudo apt -y install google-chrome-stable 

检查版本

google-chrome --version 

wget https://chromedriver.storage.googleapis.com/94.0.4606.61/chromedriver_linux64.zip 
unzip chromedriver_linux64.zip 
sudo mv chromedriver /usr/bin/chromedriver 
sudo chown root:root /usr/bin/chromedriver 
sudo chmod +x /usr/bin/chromedriver
