Headless Chrome无法启动：调试卡在driver.get行求助

Hey there, let's break down why your headless Chrome is getting stuck on driver.get() and how to fix it. Given your setup (Windows 7, Python 3.6), there are a few key areas to check:

• Chrome Version Compatibility with Windows 7
  Chrome dropped official support for Windows 7 starting with version 109. If you've updated Chrome to the latest version, it's likely incompatible with your OS, which causes headless mode to fail silently.
  Fix: Downgrade Chrome to version 108 (the last version supporting Win7) and make sure your chromedriver matches this exact version—chromedriver and Chrome versions must always align perfectly.

• Add Critical Headless Mode Flags
  Windows 7's older system components often need extra flags to get headless Chrome running smoothly. Try adding these to your Chrome options:

  from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  
  chrome_options = Options()
  # Use --headless for Chrome <112; for 112+, use --headless=new (but stick to 108 for Win7)
  chrome_options.add_argument("--headless")
  chrome_options.add_argument("--no-sandbox")  # Bypasses OS security restrictions (critical for Win7)
  chrome_options.add_argument("--disable-gpu")  # Fixes GPU-related hangs on older systems
  chrome_options.add_argument("--disable-dev-shm-usage")  # Resolves resource limit issues
  chrome_options.add_argument("--window-size=1920,1080")  # Ensures proper page rendering
  
  driver = webdriver.Chrome(options=chrome_options)
  driver.get("your-target-site")
  

• Match Selenium Version to Python 3.6
  Python 3.6 is end-of-life, and newer Selenium 4.x versions have dropped support for it. Stick to Selenium 3.141.0, which is fully compatible with Python 3.6 and older Chrome versions:

  pip install selenium==3.141.0
  

• Check Permissions and Chromedriver Path

  • Run your Python script as an administrator (right-click > "Run as administrator")—Win7 sometimes blocks headless processes without elevated rights.
  • Double-check that chromedriver.exe is in your system PATH or explicitly specify its path in the webdriver.Chrome() call:

    driver = webdriver.Chrome(executable_path="C:/path/to/chromedriver.exe", options=chrome_options)
