mocharc.yml require not working with chai/require-expect

Given that i have added chai/require-expect to the require array in mocharc.yml When i run npx mocha Then it should include expect as a global function

-- Actually --

I get the following error:

TSError: ⨯ Unable to compile TypeScript: test/isthisforfun.spec.ts:7:9 - error TS2304: Cannot find name 'expect'.

Hack Fix If i include the library as an import in each test it passes

import { expect } from 'chai';  // Using Expect style
