我在尝试在我的React组件中导入以下内容时遇到了错误：
import FontIconPicker from '@fonticonpicker/react-fonticonpicker';
import '@fonticonpicker/react-fonticonpicker/dist/fonticonpicker.base-theme.react.css';
我正在使用这个模块：https://fonticonpicker.github.io/react-fonticonpicker/
我遇到了这个错误：
./node_modules/@fonticonpicker/react-fonticonpicker/dist/fonticonpicker.base-theme.react.css 模块解析失败：意外字符 '@' (18:0)。您可能需要一个适当的加载器来处理此文件类型。| * | / | @font-face{font-family:fontIconPicker;src:url(assets/fontIconPicker.ttf) format("truetype"),url(assets/fontIconPicker.woff) format("woff"),url(assets/fontIconPicker.svg#fontIconPicker) format("svg");font-weight:400;font-style:normal}[class=" fipicon-"],[class^=fipicon-]{font-family:fontIconPicker!important;speak:none;font-style .......
您可以使用我的github代码重现此错误：https://github.com/gregbia/my-app
使用npm install和npm start，将会显示错误。
我的webpack配置如下：
/**
* Webpack Configuration
*
* Working of a Webpack can be very simple or complex. This is an intenally simple
* build configuration.
*
* Webpack basics — If you are new the Webpack here's all you need to know:
* 1. Webpack is a module bundler. It bundles different JS modules together.
* 2. It needs and entry point and an ouput to process file(s) and bundle them.
* 3. By default it only understands common JavaScript but you can make it
* understand other formats by way of adding a Webpack loader.
* 4. In the file below you will find an entry point, an ouput, and a babel-loader
* that tests all .js files excluding the ones in node_modules to process the
* ESNext and make it compatible with older browsers i.e. it converts the
* ESNext (new standards of JavaScript) into old JavaScript through a loader
* by Babel.
*
* TODO: Instructions.
*
* @since 1.0.0
