我在使用React.js在第一次渲染时渲染我的Ant-Design CSS时遇到了一个问题。我有一个非常基本的页面，它只是渲染一个按钮。

import React from 'react';

import { Button } from 'antd';

const LoginPage = () => {
    return (
        <div>
            <Button type="primary">Button</Button>
        </div>
    )
};

export default LoginPage;

我尝试通过config-overrides.js文件导入Ant-Design模块，如文档所示：

const { override, fixBabelImports } = require('customize-cra');

module.exports = override(
    fixBabelImports('import', {
        libraryName: 'antd',
        libraryDirectory: 'es',
        style: 'css',
    }),
);

下面是我的index.js文件：

import { Provider } from 'react-redux';
import thunkMiddleware from 'redux-thunk';
import { createStore, applyMiddleware } from 'redux';

import 'normalize.css';

import App from './components/App/App';
import reducers from './reducers';
import { fetchUser } from './actions';

import * as serviceWorker from './serviceWorker';

const store = createStore(reducers, applyMiddleware(thunkMiddleware));

store.dispatch(fetchUser()).then(() => console.log(store.getState()));

ReactDOM.render(
    <Provider store={store}>
        <App />
    </Provider>,
    document.getElementById('root')
);

serviceWorker.unregister();

下面是我的App.js和App.css，以供参考：

import React, { Component } from 'react';
import LoginPage from '../LoginPage/LoginPage';
import DashboardPage from '../DashboardPage/DashboardPage';

import { Spin } from 'antd';

import './App.css';

import { connect } from 'react-redux';

class App extends Component {

    constructor(props){
        super(props);
        this.state = {
            loggedIn: false
        }
    }

    componentDidMount(){
        this.setState({loggedIn: true });
    }

    render() {
       return <LoginPage/>
    }
}

const mapStateToProps = (state) => {
    console.log(state);
    return {
        user: state.currUser
    };
};

export default connect(mapStateToProps)(App);

@import '~antd/dist/antd.css';

然而，在第一次渲染时，它只会显示一个正常的按钮，然后在一秒钟后自行修复。下面是两个显示问题的图像：
