Answer 1

Before running npm start execute npm i @ level where you have your package.json also execute bower i if you have bower.json

check for node in environment variables using SET in cmd.

Answer 2

I found this issue on github. Apparently, this error appears if there is a mistake in your environment variables. Open your PATH variable on windows and check if there are any strange semicolons or flags in the dialog window:

.

If so, fix them and try again
