Report #26445

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

Run the underlying script command directly \(e.g., ./node\_modules/.bin/jest or npx jest\) bypassing npm's wrapper to see the actual error stack trace, then fix the underlying syntax or runtime error in the test/build code.

Journey Context:
Developer runs npm test or npm run build. The command fails with "npm ERR\! code ELIFECYCLE" and "Exit status 1", with npm's log helpfully noting "This is probably not a problem with npm". The actual error output from the test runner or compiler is buried above in the logs or truncated. Developer assumes node\_modules is corrupted and runs rm -rf node\_modules && npm install, wasting time. They try npm cache clean --force. They check for disk space. Eventually, they scroll up past npm's error wrapper and see the actual Jest error \(syntax error in test file\) or webpack compilation error. They run the script binary directly from node\_modules/.bin/ to see the unwrapped output, fix the actual code bug, and the ELIFECYCLE error disappears because the underlying script exits 0.
