I figured out solution to my own question. To answer it to myself, and to those may encounter the same issue with me, post solution here.

In this document https://developers.arcgis.com/experience-builder/guide/install-guide Step 8, instruct to run npm ci. Acutally, if you don't have npm ci avaliable on your machine, run npm ci will do nothing. So to new user like me, this document should add a note to guide user to install npm ci properly before go to Step 9. Otherwise, if run npm ci fail (actually, nothing happen), then running npm start (Step 9) will generate errors I posted above.
