using assert with ts-node in mocha test

I created a mocha test in a test.ts

I created a mocha test in a test.ts

import * as assert from "assert";

describe('it', () => { it('should ', done => { assert.strictEqual(true, false); done(); }); });

My package.jsons devDependencies:

"devDependencies": {
    "@types/mocha": "^5.2.5",
    "@types/node": "^10.12.18",
    "mocha": "^5.2.0",
    "ts-node": "^8.0.1",
    "typescript": "^3.2.4"


  "compilerOptions": {
    "target": "es2015",
    "module": "commonjs",
    "sourceMap": true,
    "declaration": true,
    "outDir": "./dist",
    "strict": true,
    "types": ["mocha"]

When running ts-node, I get this error:

error TS2307: Cannot find module 'assert'.

My commandline call is this:

./node_modules/mocha/bin/mocha -r ts-node/register test/test.ts

Regular tsc throws no errors.
