Angular 4 : "Cannot find name ' require'

Question

我正在使用 Angular 4 和 webpack 构建应用。

我的一个组件中包含以下内容:

ngOnInit() {
    require('/assets/js/regular-expresions.js');
}

当我尝试编译时，我得到:

ERROR in C:/SRC/Sandbox/eat-sleep-code.com/src/app/content.component.ts (21,9): Cannot find name 'require'.

我已经运行了 npm install @types/node --save-dev 并将我的 tsconfig.json 更新为如下所示:

{
  "compileOnSave": false,
  "compilerOptions": {
    "outDir": "./dist/out-tsc",
    "baseUrl": "src",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "types": [
      "node"
    ],
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2016",
      "dom"
    ]
  }
}

但是，唉，同样的错误不断被抛出。有什么想法吗？

尝试在顶部添加 declare var require: any;。
