I'm starting a project to study Angular2, and for this I'm using Debian 8 with node v6.3.1 (npm v3.10.3).
Following the Angular2 official quickstart walkthrough :
#git clone https://github.com/angular/quickstart my-proj
#cd my-proj
#rm -rf .git
#npm install
npm WARN lifecycle [email protected]~postinstall: cannot run in wd %s %s (wd=%s) [email protected] typings install /var/angular2/my-proj
npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: [email protected]
npm WARN optional Skipping failed optional dependency /browser-sync/chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: [email protected]
#
#npm start
When you run npm start , then a plethora of errors appear:

My question: why these mistakes are happening? How can I resolve them?
Update ......... 07/28/2016 14:36
Started working after performing the procedure described by Rodrigo Rigotti
See if you have a typings folder in your project; if not, turn the command npm run typings - install . If so, try changing the attribute "target" in the typings.json file for "es6".
However, some WARNs remain when running npm install :
npm WARN lifecycle [email protected]~postinstall: cannot run in wd %s %s (wd=%s) [email protected] typings install /var/angular2/my-proj
npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: [email protected]
npm WARN optional Skipping failed optional dependency /browser-sync/chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: [email protected]
Thanks in advance for any help in understanding or solving these WARNs.
