下面是我的tsconfig.json文件

{
    "compilerOptions": {
        "target": "es5",
        "module": "commonjs",
        "moduleResolution": "node",
        "sourceMap": true,
        "experimentalDecorators": true
        // "outDir": ""
    },
    "buildOnSave": false,
    "compileOnSave": false,
    "exclude": [
        "node_modules"
    ],
    "awesomeTypescriptLoaderOptions": {
        "useWebpackText": true
    }
}

下面是我的webpack配置文件：

/**
 * 开发环境webpack配置
 */
const path = require('path');

module.exports = {
    entry: {
        app: './src/main.ts',
    },
    output: {
        path: path.join(__dirname, 'build'),
        filename: '[name].bundle.js'
    },
    resolve: {
        extensions: ['', '.ts', '.js', '.json']
    },
    module: {
        loaders: [
            {
                test: /\.ts$/,
                loaders: ['awesome-typescript-loader', 'angular2-template-loader'],
                exclude: /(node_modules | libs)/
            },
            {
                test: /.less$/,
                loader: 'less',
                exclude: /(node_modules | libs)/
            },
            {
                test: /.html$/,
                loader: 'raw-loader'
            }
        ]
    }
}

Answer 1

原因：
awesome-typescript-loader 最新的2.x的版本，只兼容 typescript 2.x的版本（目前正式版只到1.8）。

---

解决办法：
方案一： 升级 typescript 到预览版

npm i typescript@next --save-dev

方案二： 使用awesome-typescript-loader 的1.x的版本

npm i awesome-typescript-loader@1.1.1 --save-dev

Answer 2

已经找到解决方案，需要更新下typescript到最新版本即可。

npm install typescript@next --save-dev
