  }
}

我的 webpack.config.babel.js 

import path from 'path';
const ExtractTextPlugin = require("extract-text-webpack-plugin");

console.log("DIR: " + __dirname);
const config = {
    entry: {
        js: './src/client/app-client.js',
    },
    output: {
        path: path.join(__dirname, 'src', 'client', 'static', 'js'),
        filename: 'bundle.js',
    },
    module: {
        rules: [
            {
                test: [/\.jsx$/, /\.js$/], //path.join(__dirname, 'src'),
                exclude: ["bower_components", "node_modules"],
                use: {
                    loader: 'babel-loader',
                    options: 'cacheDirectory=.babel_cache',
                },
            },

            {
                test: /\.css$/,
                use: [
                    { loader: 'style-loader' },
                    { loader: 'css-loader' }
                ],
                include: [
                    path.resolve(__dirname, "src","client")
                ],
            }

        ]



    },
    plugins: [

    ]
    ,

};

export default config;

示例用法(也尝试导入"./text.css"):

sample usage (also tried import "./text.css"):

import React from 'react';   
import css from './text.css';


export class Test1 extends React.Component {


 render() {
    return (<div className="test">
      Test1 File

    </div>
    );
  }
}

export default Test1;

text.css 

.test{ 
    background: blue;
    font-size: 1.234px; 
}

我已经待了好几个小时了，似乎无法找到问题所在.

Ive been at it for hours, cannot seem to find what is wrong.

推荐答案

我必须从以下位置删除:

I had to remove from:

{
  test: /\.css$/,
  use: [
         { loader: 'style-loader' },
         { loader: 'css-loader' }
       ],
       include: [
                    path.resolve(__dirname, "src","client")
       ],
}

收件人:

 {
      test: /\.css$/,
      use: [
             { loader: 'style-loader' },
             { loader: 'css-loader' }
           ],
    }

这对我来说很有效.我不知道为什么.

This one works in my case. I don´t know why.
