TS2305

error TS2305: Module ‘./sum‘ has no exported member ‘multiply‘.

Broken Code ❌

1

export function sum(a: number, b: number): number {
  return a + b;
}

1

import { multiply } from './sum';

console.log(multiply(1, 2));

Fixed Code ✔️

The file “sum.ts” exports a function named “sum”, so we have to fix the named import in our “main.ts” file:

1

3

import { sum } from './sum';

console.log(sum(1, 2));
