using assert with ts-node in mocha test

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”

}

tsconfig.json:

{

“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.
