The dependencies are not being installed

Steps to reproduce:

npm install react-plotly.js plotly.js
npm start

Errors:

Module not found: Error: Can't resolve 'buffer/'
Module not found: Error: Can't resolve 'stream'
webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.
Module not found: Error: Can't resolve 'assert' in

Installing 
"@types/plotly.js": "^2.12.30",
 "plotly.js-dist-min": "^2.27.1"
    
 and 
 import Plotly from "plotly.js-dist-min";

this worked for me.
