## Current Behavior
The publish workflow was failing because the preinstall script was
exiting with code 1 when detecting an older Node.js version, causing the
entire publishing process to fail.
## Expected Behavior
The preinstall script should warn about Node.js version requirements but
not exit with an error code during publishing, allowing the workflow to
continue.
## Related Issue(s)
This fixes a critical issue preventing package publishing due to Node.js
version check failures in CI environments.
The fix changes:
- `console.error()` to `console.warn()` for better log categorization
- Removes `process.exit(1)` to prevent workflow termination
- Adds the actual Node.js version to the warning message for better
debugging
This ensures the publish workflow can complete successfully while still
providing visibility into Node.js version mismatches.
