Prime React css 样式不适用于 Reactjs 应用程序

Question

我正在开发一个 React JS 应用程序，我添加了 ReactBootstrap 和 PrimeReact 库来进行样式设置。Reactbootstrap 库工作正常，但是 primereact 样式没有得到应用，我已按照入门部分中的所有步骤进行操作，任何人都可以建议我缺少什么。我正在添加文件以供参考。我使用以下命令在节点模块中添加文件

• npm 安装 primereact --save

• npm 安装 primeicons --save

应用程序.js 文件

import logo from './logo.svg';
import './App.css';
import Header from './MyComponents/Header'
import 'bootstrap/dist/css/bootstrap.min.css';
import 'primereact/resources/primereact.min.css';
import 'primeicons/primeicons.css';       
import {Todos} from './MyComponents/Todos'
import {TodoElements} from './MyComponents/TodoElements'
import {Footer} from './MyComponents/Footer'

function App() {
  
  <script src="https://unpkg.com/primereact/primereact.all.min.js"></script>
  
  return (
    <><Header title='Code With Shiva' searchBar={true}/>
    <Todos/>
    <TodoElements/>
    <Footer/>
    </>
  );
}

export default App;

Todos.js 我在其中添加 primereact 风格的按钮

import React from 'react';
import { Button } from 'primereact/button';

export const Todos = () => {
    return (
        <div>
            <Button label="Success" className="p-button-success" />
        </div>
    )
}

添加package.json以供参考

  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^5.16.1",

  "eslintConfig": {
    "extends": [

      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

所有 PrimeReact 组件都需要一个主题，因此只需添加...

import "primereact/resources/themes/lara-light-indigo/theme.css";
