Intern 4: Unable to execute tests suite

I use Intern 4.0 (Yes! i know! it's an alpha version. But I want rewrite my code and unit tests in es6).

I installed the npm package "intern 4.0.0-alpha.4", I rewrited code, unit tests, and suite in es6.

But i'm unable to run tests. I want run tests from the npm scripts : I edited my package.json file to get:

"scripts": {
    "test": "node_modules/.bin/intern"
}

I 'm also tried with :

"scripts": {
    "test": "node_modules/.bin/intern config=intern.json"
}

or with the inter-cli :

"scripts": {
    "test": "intern run --config intern.json"
}

Then i run the command npm run test

Here the log file:

Have you an idea?
