Issue when installing blitzjs and ionic togther, related to es6-module

Question

When I try to install blitzjs and ionic together, it fails. It is quite easy to reproduce the issue.

npm install -g blitz
blitz new blitz-ionic

✔ Pick a new project's language · JavaScript
✔ Pick your new app template · full
✔ Install dependencies? · npm
✔ Pick a form library (you can switch to something else later if you want) · React Final Form


cd blitz-ionic/
npm install --save @ionic/react @ionic/react-router history react-router-dom

Then add this line to the file app/pages/_app.tsx

import { IonReactRouter } from "@ionic/react-router"

Now, when I run

blitz build

I obtain the following error:

> Build error occurred
/home/XXXXX/test/blitz-ionic/node_modules/@ionic/core/components/index.js:4
export { setAssetPath, setPlatformOptions } from '@stencil/core/internal/client';
^^^^^^

SyntaxError: Unexpected token 'export'

I have tried a lot but I have no idea what is going on and how to solve it...

I got the issue whether I choose typescript or javascript during blitzjs install.

If I comment the line that I just added, it works fine.

If I install just blitzjs, or just ionic, it works perfectly.
