AngularJs + typescript : error TS2307: Cannot find module 'angular'

Question

我正在尝试结合使用 Angular1.5 + Typescript。安装需要的类型:

npm install @types/angularjs

但仍然看到错误:

error TS2307: Cannot find module 'angular'

已经尝试过不同的选择:

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"]
}

已经尽可能地简化了 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:

ERROR in .../node_modules/@types/angularjs/angular-mocks.d.ts (6,26): error TS2307: Cannot find module 'angular'.

ERROR in .../node_modules/@types/angularjs/angular-mocks.d.ts (65,49): error TS2304: Cannot find name 'IServiceProvider'.

ERROR in .../node_modules/@types/angularjs/angular-mocks.d.ts (122,62): error TS2304: Cannot find name 'IScope'.

ERROR in .../node_modules/@types/angularjs/index.d.ts (66,43): error TS2304: Cannot find name 'JQuery'.

如果您在命令行中运行它应该可以解决问题。

npm install @types/angular

此修复程序令人恼火的是，出于某种原因，它不会更新您的 package.json.. 但是，如果您将以下内容添加到 package.json 中的依赖项中，而不是 上面的内容应该解决问题并让 package.json 镜像您的包。

"@types/angular": "1.6.5",
"@types/jquery": "2.0.40",
