Rails未使用本地修改版recommendable gem，仍用原版问题求助

Hey there, let's work through this issue— it's super common when tweaking local gem forks, so you're not alone! Here are the most likely fixes to get your updated gem code working correctly:

1. Verify Bundler is actually using your local gem #

First, double-check that Bundler isn't silently falling back to a remote or system-installed version of the gem. Run these commands in your app directory:

• bundle show recommendable: The output should match your local fork path (/home/aristizabal95/forked_gems/recommendable). If it doesn't, Bundler is using a different version entirely.
• gem list recommendable: Look for any installed versions that might be overriding your local fork. You can uninstall them temporarily with gem uninstall recommendable (just remember to re-install later if needed).

2. Check for missed method calls in the gem or your app #

The ArgumentError means somewhere, your modified method is being called without the new parameter you added. You need to audit two places:

• Inside the recommendable gem: Search the entire gem codebase for every instance where this method is invoked. Make sure all internal calls now include the new parameter.
• In your application code: Check any places where you directly call this method from recommendable. Update those calls to pass the new argument too.

It's easy to forget that gems often have internal dependencies on their own methods— don't just update the method definition!

3. Clear Bundler cache and reload dependencies #

Bundler sometimes caches old gem artifacts even when using a local path. Try these steps to reset:

1. Run bundle clean --force to wipe cached gem files.
2. Stop any running application servers or Spring processes (if you're using Rails, run spring stop).
3. Re-run bundle install and then restart your test environment.

This ensures your modified code is fully loaded instead of pulling from a stale cache.

4. Confirm your gem's version and loading order #

• If your Gemfile specifies a version constraint for recommendable (like gem 'recommendable', '~> 3.0', path: ...), make sure your local fork's version.rb matches that constraint. Bundler might ignore the local path if the version doesn't align.
• Check for conflicting gems: Are any other gems in your project monkey-patching the same recommendable method? That could override your changes entirely.

5. Test the gem in isolation #

To rule out issues with your app's setup, navigate to your local recommendable fork directory and run its own test suite (if it has one). If the tests pass there, the problem is likely in how your app is loading the gem— if they fail, you need to fix the method modification itself.
