});

Answer 1

Your tsconfig.json file should exclude node_modules and any d.ts files that may conflict with angular d.ts i.e:
{
"compilerOptions": {
"target": "ES5",
"module": "system",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"removeComments": false,
"noImplicitAny": false
},
"exclude":[
"fonts",
"images",
"img",
"libs",
"navigation",
"node_modules",
"pagehtmls",
"typings"
]
}

Add ngTypeings:'./node_modules/angular2/typings/**/*.ts', to gulp.config.json file and use this angular2 typing in task instead of typeings
var sourceTsFiles = [
config.ngTypeings,
config.allNgTs
]
