Angular eslint - Definition for rule typescript-eslint space-infix-ops was not found

Question

I recently removed the tslint from my angular project - I read it was depreciated, so thought I best get my hands dirty and switch to eslint.

So I removed the tslint files, ran ng add @angular-eslint/schematics to install the lint schematics, installed the Airbnb typescript linter, and amended the ng lint task to run like so...

"lint": "eslint -c .eslintrc.js --ext .ts ./src/app"

I added a .eslintrc.js file and populated it with the following

module.exports = {
  root: true,
  extends: [
    'airbnb-typescript/base',
    'plugin:@angular-eslint/recommended'
  ],
  ignorePatterns: [
    'node_modules/',
    'build/',
    'dist/',
    'e2e/'
  ],
  rules: {
    'comma-dangle': ['error', 'only-multiline'],
    'max-len': ['error', {code: 120, tabWidth: 4}],
    'no-underscore-dangle': 'off',
    'no-await-in-loop': 'off',
    'import/prefer-default-export': 'off',
    'no-param-reassign': ['error', {props: false}],
    'strict': ['error', 'global'],
    'func-names': 'off', // I use a lot of unnamed functions
    'global-require': 'off',
    'class-methods-use-this': 'off', // Disabled for Angular Controllers,
    'import/extensions': [
      'error',
      'ignorePackages',
      {
        js: 'never',
        ts: 'never',
      }
    ]
  },
  plugins: [
    '@angular-eslint/eslint-plugin'
  ],
  parserOptions: {
    project: 'tsconfig.json',
    sourceType: 'module'
  }
}

everything worked really well... but when I run ng lint I get the following error...

1:1 error Definition for rule '@typescript-eslint/space-infix-ops' was not found @typescript-eslint/space-infix-ops 1:1 error Definition for rule '@typescript-eslint/object-curly-spacing' was not found @typescript-eslint/object-curly-spacing

This is strange as I don't include rules for these in the .eslintrc.js file. I then ran an npm update hoping that may solve the issue but it doesn't. I'm currently looking through StackOverflow for an answer but if anyone has a direct answer please let me know what to do, any help is appreciated.

I'm unsure if this helps but this is the contents on my package.json
