研究方向

The issue points out that migration scripts in the meteor roles package do not delete old role documents, leaving duplicates. To fix, locate the migration script files (likely in a 'migrations' or 'server' directory), add logic to remove documents from the Roles collection that have an 'name' field matching the new role's name, or use a unique constraint. Check existing PRs or comments for more context, and ensure backward compatibility.
