Why npm build Does Not Execute the build Script in package.json: Analyzing Internal Command and Custom Script Conflicts
This article delves into the root cause of why the npm build command fails to execute custom build scripts defined in package.json. By examining npm's internal command mechanism, it reveals that npm build, as an internal command used for building native C/C++ Node addons, overrides user-defined scripts with the same name. The paper explains the correct method to run custom scripts—using npm run build—and compares it with other shortcut commands like npm start. Additionally, practical code examples are provided to demonstrate how to avoid such conflicts and ensure smooth build processes.
