我试图将express-react-views用作Express View引擎，但是它只在没有ES6的JSX中编译React代码。我该如何切换到ES6。
这是我用于“错误”页面的代码：
import React, { Component } from "react";
class Error extends Component {
render() {
return <p>{this.props.error}</p>;
}
}
export default Error;
这是我的错误：
SyntaxError: /Users/mac/Documents/ReactJS-dev/test/views/error.jsx: Unexpected token (4:8)
