serenity-js报错：TypeError: _.chain(...).toPairs is not a function 求助

Hey there, let's work through this issue step by step since you've already tried deleting node_modules and Jan's suggested fixes without luck. Here are targeted troubleshooting ideas to narrow down the problem:

• Fix the incomplete arc-merge-languages script
  Your package.json snippet cuts off at "arc-merge-languag... — first, double-check that this script is fully defined. If it's a custom script pointing to a local file, confirm the file exists in your project root and has the correct permissions (run chmod +x path/to/your-script.js if it's a Node script).

• Wipe npm/yarn cache entirely
  Deleting node_modules doesn't always clear cached package data that might be causing conflicts. Run these commands to reset the cache, then re-install dependencies:

  # For npm users
  npm cache clean --force
  rm -rf package-lock.json
  npm install
  
  # For yarn users
  yarn cache clean
  rm -rf yarn.lock
  yarn install
  

• Validate Angular dependency compatibility
  Mismatched versions of @angular/cli, @angular/core, or related packages often break builds. Run ng version to check for version gaps, then cross-reference your dependencies against Angular's official compatibility guidelines. Update mismatched packages incrementally (avoid jumping major versions all at once to prevent new issues).

• Test the arc-merge-languages script in isolation
  Instead of running npm start or npm build, execute the problematic script directly to isolate where things fail:

  npm run arc-merge-languages
  

  If this command throws an error, you’ll know the issue lies with this custom script—not the Angular build pipeline itself.

• Check for missing configs or environment variables
  If arc-merge-languages relies on external files (like language JSONs) or environment variables, confirm those are present and correctly referenced in your project. Missing assets or undefined variables can silently break scripts without clear error messages.

• Reinstall Angular CLI globally and locally
  A corrupted CLI installation can cause unexpected build issues. Refresh both global and local CLI instances with:

  npm uninstall -g @angular/cli
  npm install -g @angular/cli
  npm uninstall @angular/cli
  npm install @angular/cli
  

• Capture and analyze the full error output
  You mentioned seeing the same error as a prior post, but sharing the complete error message (including stack trace) would help pinpoint the root cause. Look for keywords like "missing module", "invalid syntax", or "permission denied"—these are usually direct clues to the problem.
