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

Examine the logs immediately preceding the ELIFECYCLE error to identify the actual underlying error \(e.g., a syntax error in the test file, a missing environment variable, or a compiler OOM kill\). Fix that specific root error. If the error is ENOMEM \(process killed\), increase Node's heap size with node --max-old-space-size=4096.

Journey Context:
A developer runs npm test in a CI pipeline. The job fails with "npm ERR\! code ELIFECYCLE" and "npm ERR\! errno 1" at the bottom of a long log. The developer scrolls up and sees only minified webpack output or Jest's final summary. Initially, they assume npm itself is broken. The rabbit hole reveals that ELIFECYCLE is not an npm bug but a wrapper error indicating that the spawned subprocess \(the lifecycle script defined in package.json scripts\) exited with a non-zero status code \(errno 1 is EPERM/General Error\). The developer adds --verbose to the npm command and sees that Jest is actually failing because a test file has a syntax error, or that the build script is being killed by the Linux OOM killer \(exit code 137\). The fix works because it addresses the actual underlying failure in the subprocess \(fixing the syntax error or increasing memory\) rather than treating the ELIFECYCLE wrapper as the problem. Once the subprocess exits with code 0, npm considers the lifecycle complete and does not throw ELIFECYCLE.
