AngularJs打字稿：错误TS2307：找不到模块’angular’

npm install @ types / angularjs

但仍然看到错误：

error TS2307: Cannot find module ‘angular’

已尝试过不同的选择：

import 'angular';
import 'angularjs'; //that is name inside @types
import angular from 'angularjs';
import * as angular from 'angular';

我正在使用：

"ts-loader": "1.0.0","typescript": "2.0.7","webpack": "1.13.3","webpack-dev-server": "1.16.2"

tsconfig非常标准：

{
  "compilerOptions": {
    "target": "es5","noImplicitAny": false,"sourceMap": false,"lib": ["es6","dom"],"typeRoots": ["./node_modules/@types"]
  },"exclude": ["node_modules"]
}

已经简化了webpack配置：
var webpack = new require(‘webpack’);

module.exports = {
  context: __dirname + '/src',entry: './index.ts',output: {
    path: './dist',filename: 'app.bundle.js'
  },module: {loaders: [{test: /.tsx?$/,loader: 'ts-loader'},]},resolve: {
    extensions: ['','.webpack.js','.web.js','.ts','.tsx','.js'],},plugins: [new webpack.NoErrorsPlugin()],devtool: 'source-map',devServer: {
    contentBase: './dist',historyApiFallback: true,inline: true
  }
};

我还简化了index.ts本身,只关注类型导入：

import * as angular from 'angular';
angular.module('testmodule',[]);

UPD：tsconfig.json.添加了typeRoots选项.

现在出现新错误：
