Error: Cannot find module 'selenium-selenium'

Question

Versions are:

nvm --version 0.35.3
npm -v: 6.14.8
node -v: v14.10.0

important package.json parts:

{
  "main": "index.js",
  "scripts": {
    "start": "./node_modules/mocha/bin/mocha index.js",
    "install": "bash install.sh",
    "clear": "rm -R -f node_modules && rm package-lock.json"
  },
  "dependencies": {
    "chromedriver": "^84.0.1",
    "dotenv": "^8.2.0",
    "mocha": "^8.1.2",
    "selenium-webdriver": "^4.0.0-alpha.7"
  }
}

index.js:

require('dotenv').config()

const password = process.env.PASSWORD;

const selenium = require('selenium-selenium');
const chrome = require('selenium-selenium/chrome');
const chromedriver = require('chromedriver');

describe('Init driver and login', () => {
  //... Should run through as an empty test but does not
});

and the error I'm getting when I'm running mocha index.js or npm run start:

Error: Cannot find module 'selenium-selenium'

As simple as possible, but the module is not found - why? Should I try the lowest versions possible? I wanted to avoid the compatibility hell so I used only the newest versions available.

I think you use incorrect package name in your code - selenium-selenium. This package is not available on npmjs.org.

Try change this lines in our code:

const selenium = require('selenium-webdriver');
const chrome = require('selenium-webdriver/chrome');
