Typescript node-fetch import throws 'SyntaxError: Cannot use import statement outside a module'

As title says, I'm in trouble with the creation of a typescript library npm package. My issue come when trying to import node-fetch to perform fetch calls. I've created this sample git repo that reproduce my problem.

I've used those command to come at this point:

npm i --save-dev typescript ts-node jest @types/jest ts-jest
jest --init
npm i node-fetch

I've configured package.json as:

"main": "dist/index.js",
"types": "dist/index.d.ts",
"files": [
  "/dist"
],
"scripts": {
  "test": "jest --coverage",
},

I've configured tsconfig.json as:

{
  "compilerOptions": {
    "module": "commonjs",
    "target": "es2015",
    "declaration": true,
    "outDir": "./dist"
  },
  "include": ["src/**/*"]
}

My jest.config.js contains:

module.exports = {
  preset: "ts-jest",
  testEnvironment: "node",
  transformIgnorePatterns: ["/node_modules/"],
};

When I run npm text the result is the following:

> tslib@0.1.0 test
> jest --coverage

 FAIL  tests/unit/index.test.ts
  ● Test suite failed to run

    Jest encountered an unexpected token

    Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax.

    Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration.

    By default "node_modules" folder is ignored by transformers.

    Here's what you can do:
     • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it.
     • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript
     • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
     • If you need a custom transformation specify a "transform" option in your config.
     • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

    You'll find more details and examples of these config options in the docs:
    https://jestjs.io/docs/configuration
    For information about custom transformations, see:
    https://jestjs.io/docs/code-transformation

Does anyone have any advice for me? How can I use node-fetch in my Typescript project?

Edit 1: using Got installed with the command npm i got I obtain the same error.

Edit 2: added jest.config.js file content
