TS2304具有的WebPack 2和2角(TS2304 with Webpack 2 and An

我一直在关注角度的文档关于如何使用的WebPack 2角2，我的代码（SRC的GitHub 这里 ）建立了与webpack.dev.js场景。

使用运行开发建设npm start （即webpack-dev-server --inline --progress --port 8080 ）给出了一系列的TS2304的错误，如

ERROR in [at-loader] src\app\app.component.ts:5:15
    TS2304: Cannot find name 'require'.

ERROR in [at-loader] src\app\app.component.ts:6:14
    TS2304: Cannot find name 'require'.

这是怎么回事了？

Answer 1:

请确保你已经安装了@types/node 。

然后写"types": ["jasmine","node"]在tsconfig.json文件，则该错误将删除。

因为同样的错误也被我面对的问题。 该解决方案为我工作。

我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"]
  }
}

和的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:

你需要Node.js的分型。

npm install @types/node --save-dev

Answer 3:

添加此我tsconfig.json固定对我来说：

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

我跑进了问题之后的角2的WebPack介绍（ https://angular.io/docs/ts/latest/guide/webpack.html ）

指南中的tsconfig.json码是在“最终结果” zip文件不同的代码（ https://angular.io/resources/zips/webpack/webpack.zip ）

这里是我的整个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/"
        ]
    }
}
