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

Scroll up in the logs to find the actual underlying error \(e.g., TypeScript compilation error, webpack config issue\); run the script directly with 'npx ' or 'node\_modules/.bin/' to bypass npm's error wrapping and see clean output.

Journey Context:
Developer runs 'npm run build' and the terminal fills with npm's error summary: 'npm ERR\! code ELIFECYCLE npm ERR\! errno 1 npm ERR\! [email protected] build: webpack' followed by a long path to the debug log. The actual error message \(e.g., 'Module not found: Error: Can't resolve './components/Header' in './src''\) is buried 50 lines above the ELIFECYCLE summary, scrolled out of view in the terminal buffer. Developer initially thinks it's an npm issue and deletes node\_modules, but the error persists. After learning that ELIFECYCLE simply means 'the script exited with code 1', the developer scrolls up or pipes output to a file, finds the actual webpack/TypeScript/Jest error, fixes the import path or syntax error, and the ELIFECYCLE disappears.
