Hi @tjx666, thanks for the issue. The sourceMappingURL comment is autogenerated by rollup and helps navigate to the source map file and finally to the original source code during debugging. I believe this comment is generated by rollup because of sourcemap: true in rollup.config.js.

You should set sourcemap: false when build for production, or it will cause debugger tools issue because you declare the sourceMappingURL but not actually exists;

This is a bug. We should remove sourcemap:true in rollup.config.js.

@tjx666 do you want to submit a pull request for this?
