angular - 带有 Webpack 2 和 Angular 2 的 TS2304

Question

我一直在关注 Angular 的 documentation关于如何将 webpack 2 与 angular 2 一起使用。我的代码 (github src here ) 是使用 webpack.dev.js 场景设置的。

使用npm start(即webpack-dev-server --inline --progress --port 8080)运行开发构建会给出一系列 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

确保你已经安装了@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
