Report #35498

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

Scroll up in the terminal output to find the specific error message above the ELIFECYCLE line \(e.g., "Module not found", "Jest: Test failed", "TypeScript compilation error", "Command not found"\). Fix that underlying issue \(install missing dependency, correct syntax error, add environment variable\). The root cause is that npm scripts are shell commands that exit with code 1 when they fail; ELIFECYCLE is just npm's wrapper error indicating the script failed, not the actual error.

Journey Context:
You run npm test or npm run build and the terminal floods with red text ending in "npm ERR\! code ELIFECYCLE" and "npm ERR\! errno 1". You panic and immediately run rm -rf node\_modules && npm install as a reflex. The error persists. You search the error code online and find StackOverflow posts saying "check the logs above." You scroll back up through hundreds of lines of output and spot, buried above, "Error: Cannot find module 'webpack'" or "SyntaxError: Unexpected token" in your source code. You realize the ELIFECYCLE error is just npm's way of saying "the script crashed," and the real error is always higher up. You fix the missing dependency or syntax error, and the ELIFECYCLE disappears.
