根据react-datepicker文档，我尝试导入css文件，但 react 会抛出错误，因为You may need an appropriate loader to handle this file type. 我已经包含css-loader在webpack-config文件中。有什么遗漏吗？以下是文件的import一部分jsx

import React, { Component } from 'react';
import moment from 'moment';
import DatePicker from 'react-datepicker';
import 'react-datepicker/dist/react-datepicker.css';

以下是 webpack.config.js

const Notifier = require('webpack-build-notifier');
const path = require('path');

const plugins = [new Notifier({ title: 'Webpack' })];
const output = path.join(__dirname, 'public', 'javascripts');

const babelConfig = {
  presets: [
    ['@babel/preset-env', {
      useBuiltIns: 'usage',
      targets: {
        browsers: [
          'last 2 versions',
          'ie >= 11',
        ],
      },
    }],
    '@babel/react',
  ],
};

const cssConfig = [
    { loader: 'style-loader' },
    { loader: 'css-loader', options: { importLoaders: 1 } },
    { loader: 'postcss-loader' },
];

const sassConfig = [
  { loader: 'style-loader' },
  { loader: 'css-loader', options: { importLoaders: 1 } },
  { loader: 'postcss-loader' },
  { loader: 'sass-loader' },
];

module.exports = {
  entry: { bundle: ['./src/client/router.jsx'] },
  output: { filename: '[name].js', path: output },
  devtool: 'source-map',
  resolve: { extensions: ['.js', '.jsx', '.json', '.css', '.scss'] },
  module: {
    rules: [
      {
        test: /\.css$/,
        exclude: /node_modules/,
        use: cssConfig,
      },
      {
        test: /\.scss$/,
        exclude: /node_modules/,
        use: sassConfig,
      },
      {
        test: /\.jsx?$/,
        exclude: /node_modules/,
        loader: 'babel-loader',
        query: babelConfig,
      },
    ],
  },
  plugins,
};

import DatePicker from "react-datepicker"
require('react-datepicker/dist/react-datepicker.css')

它应该工作

问题是它react-datepicker本身是一个节点模块，它本身包含css文件。我通过手动复制和粘贴这些css文件使其工作在项目位置中除nodu_modules文件夹之外的某个位置（因为这被 webpack 配置排除在外）
