Js | webpack LOADER报错！！！

ERROR in ./style.css 1:5
Module parse failed: Unexpected token (1:5)
You may need an appropriate loader to handle this file type.
> body {
|     background: yellow;
| }
 @ ./index.js 1:0-22
 @ multi ./index.js ./bundle.js

解决办法：在目录下添加webpack.config.js文件

module.exports = {
    module: {
      rules: [
        { test: /\.css$/, use: 'css-loader' },
        { test: /\.ts$/, use: 'ts-loader' }
      ]
    }
  };
