I am trying to follow a first example from https://mochajs.org/

Done this

$ npm install -g mocha

Got

C:Windowssystem32>npm install -g mocha

npm WARN deprecated [email protected]: Jade has been renamed to pug, please install th

e latest version of pug instead of jade

npm WARN deprecated [email protected]: graceful-fs version 3 and before will fai

l on newer node releases. Please update to graceful-fs@^4.0.0 as soon as possibl

e.

Also installed chai (sorry, I originally forgot to mention it)

C:Windowssystem32>npm install -g chai

[email protected] C:UsersTestUserAppDataRoamingnpmnode_moduleschai

├── [email protected]

└── [email protected] ([email protected])

And here is the code

var assert = require('chai').assert;

describe('Array', function() {

  describe('#indexOf()', function () {

    it('should return -1 when the value is not present', function () {

      assert.equal(-1, [1,2,3].indexOf(5));

      assert.equal(-1, [1,2,3].indexOf(0));

    });

  });

});

Keep getting

Error: Cannot find module 'chai'

What am I doing wrong?
