'How to make Next.js "see" the react-dom package?

This is my first ever Next.js project, and I encountered an odd obstacle. Even though I made sure at least 3 times that I have react-dom and react installed and up-to-date, during next, next build or next run the process aborts with the message:

The module 'react-dom' was not found. Next.js requires that you include it in the 'dependencies' of your 'package.json'. To add it, run 'npm install --save react-dom',

Error: Cannot find module 'react-dom/server',

and:

Error: > Build failed because of webpack errors.

Reading on similar problems, I did a couple of things suggested that actually fit my problem, like removing node_modules and doing yarn, reinstalling react-dom and react, but none of these helped. Deploying on Now.sh (on which I'm planning to deploy this site) also returns with an error.

This is my package.json:

{
  "dependencies": {
    "next": "^9.0.2",
    "react": "^16.8.6",
    "react-dom": "^16.8.6"
  },
  "scripts": {
    "dev": "next",
    "build": "next build",
    "start": "next start"
  }
}

I really made sure the result should be the browser opening my project on localhost:3000, but all of the Next.js commands that could make or lead to making this happen abort. Any ideas? Don't hesitate to ask for more code.

var ReactDOM = require('react-dom');

Then, do

console.log(ReactDOM)

to see specifically what sort of errors you will have on the console.
