[bug\_fix] npm ERR\! code ELIFECYCLE errno 1 \(node-sass postinstall\)

Uninstall node-sass \(npm uninstall node-sass\) and install sass \(npm install sass --save-dev\), which is the pure-JavaScript Dart Sass implementation with no native compilation.

Journey Context:
You clone a legacy React project from 2019 and run npm install. It fails at the node-sass postinstall script with ELIFECYCLE error code 1. The logs show it cannot download binding.node for your current Node.js version \(e.g., Node 18\) and attempts to compile from source but fails because Python or MSVC is missing. You check the node-sass GitHub repository and discover that node-sass is deprecated as of October 2020, and the LibSass implementation it wraps is end-of-life. The node-sass version matrix shows it doesn't support Node 16\+, and binaries are no longer built. You realize the fix isn't to install build tools to compile the deprecated package, but to migrate to the sass package \(Dart Sass\), which is the reference implementation, supports all Node versions, requires zero native compilation, and has identical JavaScript/SCSS API. You swap the packages and the project builds instantly.
