Error on npm start within examples

After following the instructions and doing the npm install , I am getting the following output upon npm start. I did verify that Typescript 2.1 is installed. I have attached npm-debug txt

c:\Development\Pluralsight\ng-ex\_examples\component-simple>npm start

> a2-first-look@0.2.0 start c:\Development\Pluralsight\ng-ex\_examples\component-simple
> npm run tsc && concurrently "npm run tsc:w" "npm run lite"

> a2-first-look@0.2.0 tsc c:\Development\Pluralsight\ng-ex\_examples\component-simple
> tsc

'concurrently' is not recognized as an internal or external command,
operable program or batch file.
