研究方向
Check the current state of the repository to see if any modules have already been migrated. Look for files using 'require' and 'module.exports' and convert them to 'import' and 'export' syntax. Pay attention to any build configuration (e.g., Babel) that may need to be updated. The main source code is likely in 'lib/' or 'src/' directory. Since the issue is old, ensure there are no conflicts with recent changes.
