[bug\_fix] npm ERR\! code ELIFECYCLE – exit status 1 on npm test/build

Scroll up in the terminal output above the npm ERR\! lines to find the actual underlying error \(syntax error, test failure, compilation error\), fix that specific issue in your code or config. The ELIFECYCLE error is just npm reporting that the script failed, not the actual error.

Journey Context:
You run npm test and see a wall of red text ending with npm ERR\! code ELIFECYCLE npm ERR\! errno 1. You panic and delete node\_modules, clear cache, reinstall, but it happens again. You think npm itself is broken. You search the error and find StackOverflow answers saying "delete node\_modules" which doesn't help. Finally, you scroll up past the npm ERR\! lines to the actual test runner output \(Jest, Mocha, etc.\) and see a syntax error in your source code, or a failing assertion. You fix that typo, run npm test again, and it passes. You realize ELIFECYCLE just means "the script exited with code 1" and npm is wrapping the real error.
