找不到模块错误--css模块

Question

第import * as Styles from './ButtonStyle.css';行引发错误[ts] Cannot find module './ButtonStyle.css'

我的组件：

require('./ButtonStyle.css');

import * as React from 'react';
import * as Styles from './ButtonStyle.css';

export interface IState{
    type: string;
    className: string;
    caption: string;
}

export class Button extends React.Component<{}, {}>{
    render(){
        return(
            <button 
                type="button" 
                className="btn btn-primary"
            >Work In Progress</button>
        );
    }
}
