[bug\_fix] npm ERR\! ELIFECYCLE Command failed with exit code 1

Scroll up past the \`ELIFECYCLE\` line to find the actual underlying error emitted by the script \(e.g., a TypeScript compiler error, a missing \`.env\` variable, or a failed test assertion\). Fix that root cause, then rerun the script. \`ELIFECYCLE\` itself only means "the script exited non-zero"; it is a symptom, not the disease.

Journey Context:
You run \`npm run build\` in a React project and the terminal ends with \`npm ERR\! ELIFECYCLE Command failed with exit code 1\`. You focus on the npm error and try \`npm cache clean --force\` and deleting \`node\_modules\`, but it keeps failing. Then you scroll up and see \`Module not found: Can't resolve './utils'\` hidden earlier in the webpack output. You fix the import path, rerun \`npm run build\`, and it succeeds. You learn that npm prints the lifecycle wrapper error last, so the real failure always lives above it.

environment: Any npm project using lifecycle scripts \(\`build\`, \`test\`, \`start\`, etc.\) where the invoked tool exits with a non-zero status. · tags: npm elifecycle lifecycle exit-code build test · source: swarm · provenance: https://docs.npmjs.com/cli/v10/using-npm/scripts\#exit
