Report #81406

[bug\_fix] npm ERR\! code ELIFECYCLE \(exit status 134/137\)

Root cause: ELIFECYCLE indicates the npm script exited with a non-zero exit code. Exit 134 \(SIGABRT\) or 137 \(SIGKILL\) specifically indicate the OS killed the Node process, almost always due to Out-Of-Memory \(OOM\) during heap allocation. This happens when bundlers \(Webpack, Vite, tsc\) process large dependency trees with Node's default ~1.4GB heap limit. Fix: Increase Node's max heap size by setting the environment variable NODE\_OPTIONS='--max-old-space-size=4096' \(or 8192 for 8GB\) before the command. In package.json scripts: 'build': 'NODE\_OPTIONS=--max-old-space-size=4096 webpack'. On Windows PowerShell: $env:NODE\_OPTIONS='--max-old-space-size=4096'.

Journey Context:
You run npm run build on a large React application in a CI environment \(GitHub Actions\). The build starts, processes 2000 modules, then dies with 'npm ERR\! code ELIFECYCLE' and 'npm ERR\! errno 137'. You check the GitHub Actions log and see 'Process completed with exit code 137' right after a 'JavaScript heap out of memory' message. You realize the default runner has 2GB RAM and Node defaults to 1.4GB heap, leaving no headroom for the bundler's memory-intensive optimization passes. You add an env variable to the workflow: NODE\_OPTIONS: '--max-old-space-size=4096', re-run, and the build completes because Node can now allocate up to 4GB, staying within the CI container limits while accommodating the dependency graph.

environment: Node.js default heap \(~1.4GB on 64-bit\), CI environments with limited RAM \(GitHub Actions 2GB, Docker containers\), large frontend builds \(Webpack, Vite, Rollup, tsc with composite projects\). · tags: npm elifecycle oom max-old-space-size heap out-of-memory exit 134 137 sigkill · source: swarm · provenance: https://nodejs.org/api/cli.html\#--max-old-space-sizesize-in-megabytes and https://docs.npmjs.com/cli/v10/commands/npm-run-script\#description
