找不到模块RecipeStyle.css

Question

我创建了一个css文件，并希望它包含在jsx文件中。我安装了css加载器、样式加载器和babel。我在脚本中导入了css文件，但它显示了错误消息: can not find moudle ./...

但是为什么呢？

我看了一些教程，学习了所有的东西，我甚至删除了node modules文件夹，并用npm install重新加载了它。

Recipe.jsx

import React from 'react';
import { IngredientFormPart } from './IngredientFormPart';

import './RecipeStyle.css';

export class RecipeForm extends React.Component {
    render() {
        return (
            <form>
                <label>
                    Name des Rezepts
                    <input
                        id="recipeID"
                        type="text"
                        />
                </label>
                <label>
                    <IngredientFormPart />
                </label>
            </form>
        )
    }
}

webpack.config.js

var path    = require('path');
var hwp     = require('html-webpack-plugin');

module.exports = {
    entry: path.join(__dirname, '/src/index.jsx'),
    output: {
        filename: 'build.js',
        path: path.join(__dirname, '/dist')
    },
    module: {
        rules: [
          {
            test: /\.(js|jsx)$/,
            exclude: /node_modules/,
            use: {
              loader: 'babel-loader'
            }
          },
          {
            test: /\.css$/,
            exclude: /node_modules/,
            use: [
              'style-loader',
              'css-loader'
            ]
          }
        ]
      },
      resolve: {
        extensions: [ '.js', '.jsx', 'css' ]
      },
    plugins:[
        new hwp({template:path.join(__dirname, '/src/index.html')})
    ]
}

.babel配置

{
    "presets": ["@babel/preset-react", "@babel/preset-env"],
    "plugins": ["@babel/plugin-transform-react-jsx"]
}

package.json

{

尝试将resolve.extensions中的"css"更改为".css"。
