Angular2β和gulp找不到模块'angular2/core‘

Question

我正在尝试自动化的类型记录编译与新的角2.0测试版。

项目结构是：

myapp
|--node_modules
     |---angular2
            |--core.d.ts
            |--...
|--lib
    |--resources
         |--app
             |--app.component.ts
|--typings
     |--..
.
|--package.json
|--gulpfile.js

app.component.ts节选：

import {Component, View} from 'angular2/core';
import {TechnologiesService} from './services';

当我直接从shell运行typescript命令(tsc)时，一切都进行得很好，并且生成了javascript文件。但是，当我运行gulp编译任务时，会出现一些错误，因为它没有找到angular2 2/core和angular2 2/platform/browser模块。为什么？

[16:35:55] Using gulpfile C:\dev\myapp\gulpfile.js

gulpfile 类型记录编译任务

var gulp = require('gulp');
var plugins = require('gulp-load-plugins')();
var typescript = require('gulp-tsc');
gulp.task('compile-ts', function(){
  return gulp.src(['./lib/resources/app/**/*.ts'])
    .pipe(typescript({"target": "es5", "module": "system", "moduleResolution": "node", "sourceMap": true,
                      "experimentalDecorators": true, "emitDecoraasdftorMetadata": true, "removeComments": false,
                      "noImplicitAny": false}))
    .pipe(gulp.dest('./public/app/'));
});

我使用的是一体式文本，而不是gulp，下面的gulpfile.js非常适合指定的tsconfig.json文件。

var gulp = require('gulp');
var ts = require('gulp-typescript');
var path = require('path');
var sourcemaps = require('gulp-sourcemaps');

gulp.task('build:client', function () {
    var tsProject = ts.createProject('client/tsconfig.json');
    var tsResult = gulp.src([
        'client/**/*.ts',
        '!client/typings/main/**/*.ts',
        '!client/typings/main.d.ts'
    ])        
        .pipe(sourcemaps.init())
        .pipe(ts(tsProject))
    return tsResult.js
        .pipe(sourcemaps.write())
        .pipe(gulp.dest('server'))
});

gulp.task('default', ['build:client']);

我的tsconfig.json

{
  "compilerOptions": {
    "target": "es5",
    "module": "system",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false,
    "rootDir":"./"    
  },
  "exclude": [    
    "typings/main",
    "typings/main.d.ts"
  ]
}

安装台风

npm install typings --save-dev

初始化typings.json

typings init

安装“ES6-集合”和“ES6-承诺”的类型

typings install es6-collections --ambient --save
typings install es6-promise --ambient --save
