angularjs-typescript-webpack-seed doesn't run

I downloaded this boilerplate and I'm trying to run it, but when I go "npm start" I get the following error:

ERROR in ./src/app/index.ts
Module build failed: TypeError: Cannot read property 'exclude' of undefined
    at applyDefaults (/home/node/angular1.5-typescript-webpack-master/node_modules/awesome-typescript-loader/src/instance.ts:266:72)

Any help will be profoundly appreciated!
