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

Inspect the actual script error above the ELIFECYCLE line; for Windows/Unix compatibility use cross-env package; ensure signal handlers don't force exit\(1\)

Journey Context:
Developer runs npm run build on Windows and sees ELIFECYCLE error. The npm log shows the error happened in the build script, but the ELIFECYCLE code itself just means the script exited with status 1. Scrolling up, the real error is 'rm is not recognized as an internal or external command'. The package.json has "build": "rm -rf dist && webpack". On Windows, rm doesn't exist, so the shell returns exit code 1, which npm wraps as ELIFECYCLE. Developer initially thinks npm itself is broken. After researching, they install cross-env and rimraf. The fix works by replacing platform-specific shell commands with Node.js-based cross-platform utilities, ensuring the script returns exit 0 on success across all platforms. Alternatively, configuring npm to use Git Bash on Windows via script-shell config also resolves the shell incompatibility.
