npm not starting

[eddpascoal]

It seems that is not starting:

npm ERR! Linux 4.10.0-38-generic
npm ERR! argv "/usr/bin/nodejs" "/usr/bin/npm" "start"
npm ERR! node v4.2.6
npm ERR! npm  v3.5.2
npm ERR! code ELIFECYCLE
npm ERR! [email protected] start: "tsc && concurrently "tsc -w" "lite-server" "
npm ERR! Exit status 2
npm ERR! 
npm ERR! Failed at the [email protected] start script 'tsc && concurrently "tsc -w" "lite-server" '.
npm ERR! Make sure you have the latest version of node.js and npm installed.
npm ERR! If you do, this is most likely a problem with the angular2-essential-training package,
npm ERR! not with npm itself.
npm ERR! Tell the author that this fails on your system:
npm ERR!     tsc && concurrently "tsc -w" "lite-server" 
npm ERR! You can get information on how to open an issue for this project with:
npm ERR!     npm bugs angular2-essential-training
npm ERR! Or if that isn't available, you can get their info via:
npm ERR!     npm owner ls angular2-essential-training
npm ERR! There is likely additional logging output above.

npm ERR! Please include the following file with any support request:
npm ERR!     /home/mrzogs/3. Training/Angular2/angular2-essential-training/npm-debug.log

What am I missing? by the way when I do : npm install it occurs me:

npm WARN optional Skipping failed optional dependency /chokidar/fsevents: npm WARN notsup Not compatible with your operating system or architecture: [email protected] npm WARN [email protected] No license field.
