It looks like your npm install went wrong. See the next error.

npm WARN lifecycle angular2-quickstart@1.0.0~postinstall: cannot run in wd %s %s (wd=%s) angular2-quickstart@1.0.0 typings install /Users/vincentDMG/Documents/Git/angular2-tour-of-heroes

What you could do is running the command typings install. The output should look like.

> typings install
├── es6-shim (ambient)
└── jasmine (ambient)


You have got definition conflict. Check you definition references (comments that start with /// <reference path=") and make sure you do not include definitions of different libraries that provide the same polyfills.


I got the same issue, it was related to my enterprise proxy.
Added a .typingsrc file in project folder with following content fixed it.


Unfortunately typings:^1.0.4 doesn’t seems to use $http_proxy env var 🙁
At least mine was set at the moment inside my docker container.
