ChromeDriver 2.36（brew安装）页面加载超时问题求助

Hey Sam, let's dig into this frustrating timeout issue you're dealing with—nothing's worse than tools that used to work flawlessly suddenly throwing errors! Here are some targeted fixes to try, ordered by how likely they are to resolve your problem:

• Fix Version Mismatch (Most Common Cause)
  ChromeDriver 2.36 is built to work with Chrome versions 63-65, but Chrome automatically updates itself to the latest stable release. This version mismatch is almost certainly the root cause of your slow page loads and timeouts. Here's how to fix it:

  1. Check your current Chrome version: Open Chrome → click the three-dot menu → Help → About Google Chrome. Note the full version number (e.g., 118.0.5993.70).
  2. Install a matching ChromeDriver version:
     • Run brew upgrade chromedriver to install the latest stable version (this should automatically align with your updated Chrome).
     • If you need a specific older version (only if you rolled back Chrome), use brew install chromedriver@<version> (check available versions with brew search chromedriver).
  3. Verify compatibility: Run chromedriver --version in your terminal and confirm it matches your Chrome version (you can cross-reference supported versions in ChromeDriver's release details).

• Disable Extensions & Use Incognito Mode
  Outdated or misbehaving extensions can block page loads unexpectedly. Try launching Chrome in a clean state via ChromeOptions:

  options = Selenium::WebDriver::Chrome::Options.new
  # Bypass cached data and extensions with incognito
  options.add_argument('--incognito')
  # Explicitly disable all extensions
  options.add_argument('--disable-extensions')
  # Clear cache on startup
  options.add_argument('--disable-cache')
  
  driver = Selenium::WebDriver.for(:chrome, options: options)
  

• Force Disable Proxy Settings
  Even if you set the driver proxy to null, system-level or Chrome's saved proxy settings might still interfere. Add this argument to your ChromeOptions to completely bypass proxies:

  options.add_argument('--no-proxy-server')
  

  You can also manually reset Chrome's proxy settings: Go to chrome://settings/system, turn off "Automatically detect settings", and set "Proxy server" to "No proxy".

• Check for Firewall/Antivirus Interference
  Some security tools block communication between ChromeDriver and Chrome. Temporarily disable your firewall or antivirus and test if the page loads. If it works, add an exception for chromedriver and your Chrome executable in your security tool settings.

• Enable Detailed Logging to Diagnose the Root Cause
  If none of the above works, enable ChromeDriver logs to see exactly where the process is hanging:

  # Save logs to a local file for inspection
  driver = Selenium::WebDriver.for(
    :chrome,
    service: Selenium::WebDriver::Service.chrome(log_path: './chromedriver.log')
  )
  

  Open the chromedriver.log file after the timeout occurs—look for errors related to network connections, DNS resolution, or Chrome session initialization.

Start with the version mismatch fix (it's the most probable solution) and work your way down. Let me know if you hit any snags!
