Error / Issue

在学习 React 的时候，发现别人教的视频引用 uuid 的时候是通过：
import uuidv4 from 'uuid/v4

但是在本地编译的时候出错，提示：
Module not found: Can't resolve 'uuid/v4'

Root Cause

This error happens because of the file structure in node_modules/uuid, if you look there is no longer a uuidv4 to import and instead they export a v4. You could change all the places where the developers wrote uuidv4 to v4 but using the { this as that } syntax you don’t have to rewrite a bunch of code.

npm install uuid

const {v4:uuidv4} = require('uuid');

setTodo((prevTodo) => {
  return [...prevTodo, { id: uuidv4(), name: name, complete: false }];
});
