Class 找不到模块类型脚本

我想导入此模块，当我将我的应用程序与webpack和babel组合时，我不知道为什么控制台会显示此错误：

ERROR in ./src/index.ts
Module not found: Error: Can't resolve 'class-validator' in '/****/***/projects/***/****/src'
 @ ./src/index.ts 30:24-50

我导入此模块：

import {Validator} from 'class-validator';

// Validation methods
const validator = new Validator();

class GlobalEntity{}
export default Global Entity;

我的tsconfig.json是：

{
  "compilerOptions": {
    "target": "es6",
    "allowSyntheticDefaultImports": true,
    "sourceMap": true,
    "allowJs": false,
    "declaration": true,
    "experimentalDecorators": true,
    "moduleResolution": "node",
    "lib": [ "es6", "dom" ],
    "outDir": "./dist",
    "module": "CommonJS"

  },
  "exclude": ["./node_modules","dist"],
  "files": ["./typings/index.d.ts", "./src/index.ts"]
}

有人能帮我吗？ 谢谢

class-validator.ts是否与index.ts位于同一目录中？是的，是另一个人的模块，他在根目录中有index.ts
