    resolve: {

Answer 2

I met this problem when I was running 2 different versions of node:

• terminal 1: node 14, npm install
• terminal 2: node 16, npm run dev

so the dependencies are mess up, and something very strange happens.

solution:

1. remove node_modules folder
2. open 1 terminal, npm install and npm run dev
