Dumber issue with htmlparser2

Help Requests
1

We have one alpha.41 typescript + dumber app and since recently, after fresh npm install, it shows following build error

[dumber] 8.0.1      htmlparser2
[dumber] Tracing failed for node_modules/htmlparser2/lib/esm/index.js
[dumber] SyntaxError: unknown file: Export namespace should be first transformed by `@babel/plugin-proposal-export-namespace-from`.
  57 |     return getFeed(parseDOM(feed, options));
  58 | }
> 59 | export * as DomUtils from "domutils";
     |        ^^^^^^^^^^^^^
  60 | // Old name for DomHandler
  61 | export { DomHandler as DefaultHandler };
  62 |

Anyone have seen it before or any ideas how to fix?

Latest Aurelia is 2.0.0-beta.2, I had no problem to fire it up.
Project was created with npx makes aurelia new-project-name -s dumber,typescript.

Oh, I think I understand your issue now.
Your app has latest htmlparser2 as a dep, which causes dumber to fail. I will test that.

I have no problem running htmlparser2 either. Can you share your full console log? And your package.json if possible?
