带有 Webpack 2 和 Angular 2 的 TS2304

Question

我一直在关注 angular 的 documentation on how to use webpack 2 with angular 2. My code (github src here) 是根据 webpack.dev.js 场景设置的。

运行使用 npm start（即 webpack-dev-server --inline --progress --port 8080）的开发构建给出了一系列 TS2304 错误，例如

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'.

出了什么问题？

Answer 1

确保您已安装 @types/node。

然后在tsconfig.json文件中写入"types": ["jasmine","node"] 然后这个错误将被删除。

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

  }
}

Answer 2

您需要 Node.js 次输入。

npm install @types/node --save-dev

Answer 3

将此添加到我的 tsconfig.json 为我修复了它：

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

我运行进入issue如下Angular2 Webpack Intro(https://angular.io/docs/ts/latest/guide/webpack.html)

指南中的 tsconfig.json 代码与 'final result' zip 文件中的代码不同 (https://angular.io/resources/zips/webpack/webpack.zip)

这是我的全部 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/"
        ]
    }
}
