[bug\_fix] npm ERR\! code ELIFECYCLE

Scroll up in the npm log output to find the actual error message preceding the ELIFECYCLE wrapper; the real failure \(syntax error, test assertion, missing file, compilation error\) is reported by the underlying tool \(webpack, jest, tsc, node itself\). Fix that specific underlying issue. If the log is truncated \(common in CI\), run the script directly with \`npm run

Journey Context:
A developer runs \`npm test\` in a CI pipeline \(GitHub Actions\). The job fails and the visible log ends with \`npm ERR\! code ELIFECYCLE npm ERR\! errno 1\` and \`npm ERR\! [email protected] test: 'jest'\`. The developer initially believes npm itself crashed. They try re-running the job, but it fails identically. They download the full log artifact and scroll up past the npm error summary. 50 lines up, they find the actual Jest output: \`FAIL src/App.test.js\` followed by a \`SyntaxError: Unexpected token\` pointing to a missing import. They realize the ELIFECYCLE error is merely npm reporting that the \`jest\` process exited with code 1 \(test failure\). They fix the syntax error in the source file, and the CI passes. They learn to always ignore the ELIFECYCLE line and look for the tool-specific error above it.

environment: All npm versions, all platforms. Particularly confusing in CI/CD pipelines \(Jenkins, GitHub Actions, GitLab CI\) where logs are truncated or colored output is lost, showing only the final ELIFECYCLE error. · tags: npm elifecycle lifecycle-script exit-code build-error debugging log-analysis · source: swarm · provenance: https://docs.npmjs.com/cli/v8/commands/npm-run-script\#description
