为什么编译器不能读取从'../addMore/addMore'导入的addMore？

Question

我想要添加一个组件 'addMore'，但是编译器不识别它。我漏掉了什么？请帮忙。

import React from 'react'
import { MdDeleteForever } from 'react-icons/md'
import addMore from '../addMore/addMore'
import './ShoppingCardItem.css'


export default function ShoppingCardItem() {

  return (
    <div className='shoppingCardItem-Container'>
        <img src="./img/Apfel.jpg" alt="" />
        <p>2x Apfel</p>
        <addMore />
        <MdDeleteForever />
        
    </div>
  )
}

import React from 'react'

export default function addMore() {
  return (
    <div className="btn-group">
        <button type="button" className="btn btn-primary">+</button>
        <button type="button" className="btn btn-primary">-</button>
    </div>
  )
}

组件名称必须以大写字母开头。将文件名addMore.jsx重命名为AddMore.jsx，并且还要更改导入路径。查看此信息请访问React.dev功能组件

// ShoppingCardItem.jsx

import React from 'react'
import { MdDeleteForever } from 'react-icons/md'
import AddMorefrom '../AddMore/AddMore'
import './ShoppingCardItem.css'


export default function ShoppingCardItem() {

  return (
    <div className='shoppingCardItem-Container'>
        <img src="./img/Apfel.jpg" alt="" />
        <p>2x Apfel</p>
        <AddMore/>
        <MdDeleteForever />
        
    </div>
  )
}

// AddMore.jsx

import React from 'react'

export default function AddMore() {
  return (
    <div className="btn-group">
        <button type="button" className="btn btn-primary">+</button>
        <button type="button" className="btn btn-primary">-</button>
    </div>
  )
}
