Question

我一直在跟踪角度documentation关于如何使用带有角度2的webpack 2.我的代码（github src here）设置为{{1情景。

使用webpack.dev.js运行开发构建（即npm start）会出现一系列webpack-dev-server --inline --progress --port 8080错误，例如

TS2304

出了什么问题？

Answer 1

确保您已安装@types/node。

然后在"types": ["jasmine","node"]文件中写tsconfig.json 那么这个错误就会被删除。

因为我也面临同样的错误。这个解决方案对我有用。

我的tsconfig.json

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": ["es2015", "dom"],
    "noImplicitAny": true,
    "suppressImplicitAnyIndexErrors": true,
    "types": ["jasmine","node"]
  }
}

和package.json

{
  "name": "webpackCreator",
  "version": "1.0.0",
  "description": "A webpack starter for Angular",
  "scripts": {
    "start": "webpack-dev-server --inline --progress --port 8080",

  }
}

Answer 2

您需要Node.js类型。

npm install @types/node --save-dev

Answer 3

将此添加到我的tsconfig.json中为我修复了它：

"typeRoots": [ 
    "../node_modules/@types/"
]

我在Angular 2 Webpack Intro（https://angular.io/docs/ts/latest/guide/webpack.html）

之后遇到了这个问题

指南中的tsconfig.json代码与“最终结果”中的代码不同。 zip文件（https://angular.io/resources/zips/webpack/webpack.zip）

这是我的整个tsconfig.json：

{
    "compilerOptions": {
        "target": "es5",
        "module": "commonjs",
        "moduleResolution": "node",
        "sourceMap": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "lib": [ "es2015", "dom" ],
        "noImplicitAny": true,
        "suppressImplicitAnyIndexErrors": true,
        "typeRoots": [ 
            "../node_modules/@types/"
        ]
    }
}

带Webpack 2和Angular 2的TS2304
