This paper thoroughly investigates the root cause of npm or yarn reporting "No license field" warnings even when the license field is correctly set to UNLICENSED in a Node.js project's package.json file. Through a detailed case study, it reveals that package managers recursively search parent directories for package.json files during installation, potentially triggering false alarms due to outdated configuration files in upper directories lacking license fields. The article explains the meaning of path prefixes (e.g., ../) in warning messages, provides systematic methods to identify and resolve such issues, and emphasizes the importance of proper license management in private projects.
