angular - 错误 TS2300 : Duplicate identifier 'PropertyKey' in node_modules/@types/core-js/index. d.ts

Question

我在 Visual Studio Code IDE 的 node_modules/@types/core-js/index.d.ts 中有这些错误:

当我运行 npm start 来为应用程序提供服务时，我得到:

我该如何解决？

**编辑:我曾经对.d.ts 文件使用typings，但我转向了@types。我还更新了我的 npm 和节点以尝试解决此问题:

{ app: '1.0.0',
  npm: '3.10.8',
  ares: '1.10.1-DEV',
  http_parser: '2.7.0',
  icu: '57.1',
  modules: '48',
  node: '5.something',
  openssl: '1.0.2j',
  uv: '1.9.1',
  v8: '5.1.281.84',
  zlib: '1.2.8' }

为此:

{ app: '1.0.0',
  npm: '4.0.2',
  ares: '1.10.1-DEV',
  http_parser: '2.7.0',
  icu: '57.1',
  modules: '48',
  node: '6.9.1',
  openssl: '1.0.2j',
  uv: '1.9.1',
  v8: '5.1.281.84',
  zlib: '1.2.8' }

升级 "@types/core-js": "0.9.34" 到版本 0.9.39为我工作。
