Webpack 尝试解析已删除的 CSS 文件模块

如何解决Webpack 尝试解析已删除的 CSS 文件模块

我有一个 React 应用程序，我想在其中使用 webpack（和 babel）。 在遇到很多麻烦之后，我决定清理我的程序并删除我的 CSS 文件（以简化一切）。虽然我设法通过这种方式摆脱了一些错误，但我又得到了一个我根本无法修复的新错误。

现在我收到错误消息：

ERROR in ./src/App.js
Module not found: Error: Can't resolve './App.css' in 'C:\Users\Garbers\harvardedx\finalproject\finalproject\frontend\src'
 @ ./src/App.js 1:0-19
 @ ./src/index.js

我真的不知道问题出在哪里。

webpack.config.js:

const path = require("path");
const webpack = require("webpack");
const HtmlWebpackPlugin = require('html-webpack-plugin');


module.exports = {
  mode: "development",entry: "./src/index.js",output: {
    path: path.join(__dirname,"dist"),filename: "bundle.js",},devServer: {
    contentBase: path.join(__dirname,'dist'),module: {
    rules: [
      {
        test: /\.js$/,exclude: /(node_modules)/,use: {
          loader: "babel-loader"
        },],optimization: {
    minimize: true,plugins:[
    new HtmlWebpackPlugin({
        template: './dist/index.html',filename: 'index.html',inject: 'body'
    })
  ]
};

package.json：
