从 express.Router() 导入路由器

Question

我在index.js上面有这个

import express from 'express'
import favicon from 'serve-favicon'
import router from express.Router()

我不断得到

[nodemon] app crashed - waiting for file changes before starting...
[nodemon] restarting due to changes...
[nodemon] starting `babel-node ./index.js`
/Users/bheng/Desktop/express-app/node_modules/babel-core/lib/transformation/file/index.js:590
      throw err;
      ^

SyntaxError: /Users/bheng/Desktop/express-app/index.js: Unexpected token (3:19)
  1 | import express from 'express'
  2 | import favicon from 'serve-favicon'
> 3 | import router from express.Router()
    |                    ^

什么是正确的语法？我做错了什么 ？

您已经导入了 express，因此Router无需再导入即可访问。

const router = express.Router();
