Resolving npm ERR! code ENOENT Issue When Running React Native Projects

As a React Native developer, encountering errors during installation or when trying to run your application can be frustrating. One of the common issues you may face is the npm ERR! code ENOENT error, indicating that npm (Node Package Manager) can't find a necessary file, specifically the package.json. This error can halt your development process, but fret not! In this guide, we’ll explore what the error means, possible causes, and how to effectively resolve it.
