javascript - 如何让这个 React 方法返回语句/变量？

Question

这是 JobInfoPage.js 文件的片段，

import findMonthsTillSession from '../components/utility.js';

class JobInfoPage extends Component {
    render() {
            <div>The nearest hiring session is in: { findMonthsTillSession() } See you then!</div>
    }
}

我收到此错误: 尝试导入错误:“../components/utility.js”不包含默认导出(导入为“findMonthsTillSession”)。

您的问题中有 2 个错误，
(1) No return() in JobInfoPage.js文件
(2) Function is not imported with function name.
在 JobInfoPage.js

import findMonthsTillSession from '../components/utility.js';

class JobInfoPage extends Component {
    render() {
       return(
       <div>
            The nearest hiring session is in: { findMonthsTillSession() } See you then!
       </div>
       )
    }
}

添加import React from 'react';如果您还没有添加，请在 Utility.js 中添加。
