Hola, soy novato en Angular2 y cuando intento ejecutar la prueba npm con los ejemplos en el sitio oficial de angular.io, aparece este error:

 providers[name][0] is not a function TypeError: providers[name][0] is not a function at get (/Users/marcpursals/repos/..../node_modules/di/lib/injector.js:48:43) at /Users/marcpursals/repos/...../node_modules/di/lib/injector.js:71:14 at Array.map (native) at Injector.invoke (/Users/marcpursals/repos/...../node_modules/di/lib/injector.js:70:31) at Server.start (/Users/marcpursals/repos/....node_modules/karma/lib/server.js:103:18) at Promise (/Users/marcpursals/repos/..../node_modules/@angular/cli/tasks/test.js:35:25) at Class.run (/Users/marcpursals/repos/..../node_modules/@angular/cli/tasks/test.js:15:16) at Class.run (/Users/marcpursals/repos/....node_modules/@angular/cli/commands/test.js:99:25) at Class.<anonymous> (/Users/marcpursals/repos/...../node_modules/@angular/cli/ember-cli/lib/models/command.js:134:17) at process._tickCallback (internal/process/next_tick.js:103:7) npm ERR! Test failed. See above for more details.

Estoy usando angular 4.0.1 y mi paquete.json es el siguiente:

 "dependencies": { "@angular/animations": "^4.0.1", "@angular/common": "^4.0.1", "@angular/compiler": "^4.0.1", "@angular/compiler-cli": "^4.0.1", "@angular/core": "^4.0.1", "@angular/forms": "^4.0.1", "@angular/http": "^4.0.1", "@angular/material": "^2.0.0-beta.2", "@angular/platform-browser": "^4.0.1", "@angular/platform-browser-dynamic": "^4.0.1", "@angular/platform-server": "^4.0.1", "@angular/router": "^4.0.1", "@ng-bootstrap/ng-bootstrap": "^1.0.0-alpha.22", "@types/d3": "^4.5.0", "@types/jasmine": "^2.5.47", "@types/lodash": "^4.14.50", "@types/node": "^6.0.68", "bootstrap": "^4.0.0-alpha.6", ... "jasmine-spec-reporter": "^2.7.0", "jquery": "^3.1.1", ... "karma": "^1.5.0", "karma-jasmine": "^1.1.0", "karma-remap-istanbul": "^0.2.2", "lodash": "^4.17.4", .... "typescript": "^2.2.2", "zone.js": "^0.8.4" },

Intenté googlearlo pero no encontré ninguna pista. ¿Alguien enfrentó el mismo problema?
