Example code doesn't work

[hisato-kawaji]

The example code doesn't work with the error below.

Module not found: Package path ./dist/index.css is not exported from package /Users/wajiwaji/dev/livestream/react-dat-gui/example/node_modules/react-dat-gui (see exports field in /Users/wajiwaji/dev/livestream/react-dat-gui/example/node_modules/react-dat-gui/package.json)
> 1 | import 'react-dat-gui/dist/index.css';
  2 |
  3 | function MyApp({ Component, pageProps }) {
  4 |   return <Component {...pageProps} />;

I have tried the example before I run npm i in the root directory.
I think the path to index.css cannot be resolved because the path cannot not found on example/.
