我正在尝试使用新的angular 2.0 beta自动化打字稿编译。
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 摘录:
import {Component, View} from 'angular2/core';
import {TechnologiesService} from './services';
当我直接从shell运行typescript命令(tsc)时,一切顺利,并生成javascript文件。但是,当我运行我的gulp编译任务时,会出现一些错误,因为它没有找到angular2 / core和angular2 / platform / browser模块。为什么呢?

gulpfile 打字稿编译任务:
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/'));
});
答案 0 :(得分:0)
我正在使用gulp-typescript而不是gulp-tsc,以下gulpfile.js与指定的tsconfig.json文件完美配合。
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"
]
}
安装打字
npm install typings --save-dev
初始化typings.json
typings init
为“es6-collections”和“es6-promise”安装类型
typings install es6-collections --ambient --save
typings install es6-promise --ambient --save
