Following the local development setup instructions for Angular 2 at https://angular.io/docs/ts/latest/guide/setup.html on Windows 10 works for the first run of the local development environment. Both "npm install" and "npm start" work fine. However, after closing all programs and trying again to run "npm start" there are console errors and an error log file, but the browser doesn't open.

Three times I've done a fresh install/start on Angular's quickstart files, and each time it fails to run after the initial setup as described above.

Solutions in other threads didn't work or were not applicable, but I'm including the contents of package.json since some issues previously discussed have referenced that file.

I followed the instructions in the command line outputs to report the problem to the "author" but got no response.

The "Report issues" link at https://angular.io/docs/ts/latest/guide/learning-angular.html directs people to pose questions on GitHub, but the administrators on GitHub respond to a detailed post in their particular format within 20 seconds saying to post instead on StackOverflow.

I'd appreciate help in workarounds or suggestions on how to actually report problems to the Angular folks.
