[bug\_fix] npm ERR\! code ELIFECYCLE errno 1

Clear node\_modules and package-lock.json, reinstall; or check build script syntax and environment variables required by the build tool

Journey Context:
A build script \(webpack, tsc, vite\) exits with ELIFECYCLE errno 1. The logs show the command that failed but obscure the underlying error. Developers try running the script manually with --verbose, discovering it's actually a TypeScript compilation error or missing .env file. However, often the issue is corrupted node\_modules where binaries are linked incorrectly or postinstall scripts failed partially. The npm error code ELIFECYCLE simply means the subprocess returned non-zero. The robust fix is the 'nuclear option': rm -rf node\_modules package-lock.json && npm install to ensure a clean slate, then verifying build environment variables.
