Module not found: Error: Can't resolve 'core-js/fn/array' React Webpack

Question

我将 CollectionPage 的组件更改为箭头函数组件，而不仅仅是普通函数，然后我得到了这个错误，但我不知道为什么当我对很多其他组件做同样的事情时它没有抛出这个错误。这是组件代码

import { from } from 'core-js/fn/array'
import React from 'react'
import { useParams } from 'react-router-dom'
import Products from '../Products/Products'
import {H1} from '../../Style/global'

const CollectionPage=()=> {
    const {collectionTitle}= useParams()
    return (
        <div style={{marginTop:96}}>
            <H1>{collectionTitle} Collection</H1>
            <Products collectionTitle={collectionTitle}/>
        </div>
    )
}


export default CollectionPage

顺便说一句，这是一个 React webpack 项目，这是我的 webpack 配置：

const path = require('path')
const HTMLPlugin = require('html-webpack-plugin')
const CopyPlugin = require('copy-webpack-plugin');

module.exports ={
    entry :"./src/index.js",
    output:{
        path:path.resolve(__dirname,"./dist"),
        filename:'index.js',
    },
    plugins:[
        new HTMLPlugin({template:'./src/index.html'}),
        new CopyPlugin({
            patterns: [
              { from: './src/images', to: 'images' },
            ],
          }),
    ],
    module:{
        rules:[
            { 
                test : /\.js$/,
                exclude:/node_modules/,
                use:{
                    loader:"babel-loader"
                },
            },
            {
                test: /\.(png|gif|jpg)$/,
                include: [
                  path.join(__dirname, './src/images')
                ],
                loader: 'file-loader',
             },
            {
                test:/.(png|jpg|woff|woff2|eot|ttf|svg|gif)$/, //Customise according to your need
                use: [
                  {
                    loader: 'url-loader',
                    options: {
                      limit: 100000000,
                    }
                  }
               ]
            },
            {
                test: /\.js$/,
                enforce: 'pre',
                use: ['source-map-loader'],
            },
            {
                test: /\.css$/i,
                loader: 'style-loader!css-loader' 
            },
        ]
    }
}

这是错误：

./src/components/routes/CollectionPage.js Module not found: Error: Can't resolve 'core-js/fn/array' in 'C:\Users\Ora Ora\l-3afya-mafya-merch-store-react-js-\src\components\routes'

感谢 Jacobo Tapia 的评论，我意识到这是一个愚蠢的 visual studio 自动导入错误，正如您在我的组件顶部看到的那样，这个导入 import { from } from 'core-js/fn/array' 没有任何意义
