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

Scroll up in the terminal output to find the actual underlying error \(webpack compilation error, test failure, syntax error\), fix that specific root cause, or if it's an out-of-memory error, increase Node's memory with export NODE\_OPTIONS=--max-old-space-size=4096.

Journey Context:
You run npm run build or npm test and see the final error is ELIFECYCLE with errno 1. The npm error message itself is generic and doesn't say what failed. You scroll up past the npm ERR\! lines and find the actual error: 'Module not found: Error: Can't resolve ./components/Button' or 'SyntaxError: Unexpected token' or 'FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed'. You realize ELIFECYCLE just means the script exited with a non-zero code. If it's a build error, you fix the import. If it's an OOM kill, you add NODE\_OPTIONS=--max-old-space-size=4096 to the script command. You learn to always scroll up when seeing ELIFECYCLE.

environment: Any npm script execution \(build, test, start\) where the underlying tool \(webpack, jest, tsc\) exits with an error or out-of-memory crash. · tags: elifecycle npm-lifecycle exit-code build-error oom · source: swarm · provenance: https://docs.npmjs.com/cli/v8/using-npm/scripts\#npm-lifecycle-event
