Question

我正在尝试使用＆＃39; create-react-app＆＃39;在React上锻炼项目。我在同一个项目中使用Bootstrap。除了“Bootstrap Grid”之外，它似乎工作得很好。正如您在快照中看到的那样，该项目似乎选择了自定义Bootstrap字体＆amp;但是，它无法加载和拾取Bootstrap Grid布局。

我正在使用＆＃39; create-react-app＆＃39;这个项目。以下是我的文件..

package.json ..

export default App;

routes.js ..

import React from 'react';

import MainPage from './views/MainPage/MainPage.js';
import RandomPage from './views/RandomPage/RandomPage.js';
import ContactUsPage from './views/ContactUsPage/ContactUsPage.js';

import { HashRouter,Route } from 'react-router-dom';

export default function getRoutes() {
    return (
        <HashRouter>
            <div>
                <Route exact path='/' component={MainPage}></Route>
                <Route exact path='/RandomPage' component={RandomPage}></Route>
                <Route exact path='/ContactUsPage' component={ContactUsPage}></Route>
            </div>
        </HashRouter>
    );
}

我知道有一种替代方法可以使用＆＃39; React Bootstrap＆＃39;但是，我很想知道为什么Twitter Bootstrap本身没有与这个项目很好地集成。感谢。

PS：此外，控制台上没有错误或警告。

Answer 1

您正在使用Bootstrap v4（v4.0.0-beta.2），因此以下documentation适用。具体来说，这些类在v4中不存在。

Bootstrap Grid无法使用ReactJS（create-react-app）
