上代码

.m-nav-bar {background: #171a21;.content {height: 104px;margin: 0px auto;}
}

import React from "react";
import styles from  './css.module.scss'export default class NavBar extends React.Component<any, any> {constructor (props: any) {super(props);this.state = {};}render () {return (<div className={styles['m-nav-bar']}><div className={styles['content']}>内容</div></div>);}
}

导入的时候把名称改为css.module.scss
