How can I build this repository?

[superwoou]

I tried to improve this repository by fork. But I can't build . npm run build is failed with error.

> [email protected] build
> rm -rf dist && rollup -c rollup.config.ts --configPlugin @rollup/plugin-typescript && ncc build src/github-action.cjs -o action

loaded rollup.config.ts with warnings
(!) Plugin typescript: @rollup/plugin-typescript: Rollup 'sourcemap' option must be set to generate source maps.
[!] RollupError: Rollup transpiled your configuration to an  ES module even though it appears to contain CommonJS elements. To resolve this, you can pass the "--bundleConfigAsCjs" flag to Rollup or change your configuration to only contain valid ESM code.

Original error: exports is not defined in ES module scope
https://rollupjs.org/command-line-interface/#bundleconfigascjs
ReferenceError: exports is not defined in ES module scope

Also, I couldn't run the test code.
