Question

我在我的React应用程序中启用了CSS modules within webpack.config，以便我可以在本地将CSS文件范围扩展到单个组件。我也尝试使用PrimeReact中的TabView组件。当我这样做时，PrimeReact的主题不会被应用。如果我创建一个单独的项目并且不启用CSS模块，则主题应用正确。

如何使用PrimeReact主题并启用CSS模块？

我已经测试过将Tabs.js中的内容直接移动到App.js中并得到相同的结果。

启用CSS模块

Webpack.config

require.resolve('style-loader'),
          {
            loader: require.resolve('css-loader'),
            options: {
              importLoaders: 1,
              modules: true,
              localIdentName: '[name]__[local]__[hash_base64:5]'
            },
          },

App.js

import React, { Component } from 'react';
import classes from './App.css';
import Tabs from './UI/Tabs';

class App extends Component {
  render() {
    return (
        <Tabs/>
    );
  }
}

export default App;

Tabs.js

import React from 'react';
import {TabView, TabPanel} from 'primereact/components/tabview/TabView';
import classes from 'primereact/resources/primereact.css';
import theme from 'primereact/resources/themes/cupertino/theme.css';

const Tabs = () => (
        <TabView>
        <TabPanel header="Tab One">
          This is content for Tab One.
          </TabPanel>
           <TabPanel header="Tab Two">
          This is content for Tab Two.
          </TabPanel>
        </TabView>
);

export default Tabs;

默认React全局CSS范围

启用CSS模块（本地组件范围）

我能够使用CSS模块，并通过修改webpack.config有选择地将全局范围应用于PrimeReact的主题，如下所示。

使用以下两个 npm 命令安装 CSS 和样式加载器：

npm install style-loader - 如果需要，您可以添加加载的版本 npm 安装 css-loader

您无需更改任何其他内容。
