Resolving the npm run dev Error: Installing Webpack CLI for Laravel Applications

If you're working with a Laravel application and you've run into the frustrating npm run dev error that reads: "CLI for webpack must be installed," you're not alone. This problem arises often and can hinder your development progress. In this post, we will walk you through the steps to address this issue effectively.
