Report #5396

[bug\_fix] npm ERR\! code ELIFECYCLE npm ERR\! errno 1 npm ERR\! [email protected] build: \`rm -rf dist && webpack\`

Replace Unix-specific commands with cross-platform Node.js packages: use rimraf for deletion and cross-env for environment variables. Change "clean": "rm -rf dist" to "clean": "rimraf dist". Root cause: npm scripts execute in the shell \(bash on Unix, cmd.exe on Windows\), and Windows doesn't recognize Unix commands like rm, cp, or export.

Journey Context:
Developer writes a build script in package.json: "build": "rm -rf dist && NODE\_ENV=production webpack". It works on their Mac. A teammate on Windows runs npm run build and gets ELIFECYCLE error code 1. The error message shows 'rm' is not recognized as an internal command. The developer tries using del for Windows but that breaks Mac. They search and find cross-env \(for env vars\) and rimraf \(for cross-platform deletion\). They install both as devDependencies and change the script to: "build": "rimraf dist && cross-env NODE\_ENV=production webpack". The ELIFECYCLE error disappears because rimraf runs the same delete operation on both platforms, and cross-env handles the environment variable assignment correctly for both cmd.exe and bash.
