javascript - 将 react-datepicker css 加载到 jsx 文件中的问题

Question

根据 react-datepicker 文档，我尝试导入 css 文件，但 react 抛出一个错误，因为 您可能需要一个合适的加载器来处理这个文件类型。我在 webpack-config 文件中包含了 css-loader。有什么遗漏吗？以下是jsx文件

的 import部分

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,
};

在我的例子中，当使用 react_rails 时，我必须在 scss 中导入文件，该文件对应于我正在安装的主要 React 组件(app/assets/stylesheets/index.scss).

@import "react-datepicker/dist/react-datepicker";
