Question

在我的应用中添加按钮时。显示此类错误时，我无法理解。

/media/XXPath1/XXPath2/React-Wrokspace/resto/node_modules/react-bootstrap/esm/index.d.ts(2,1）中的TypeScript错误：需要声明或声明。 TS1128

    1 | export { default as Accordion } from './Accordion';
  > 2 | export type { AccordionProps } from './Accordion';
      | ^
    3 | export { default as AccordionContext } from './AccordionContext';
    4 | export { default as AccordionCollapse } from './AccordionCollapse';
    5 | export type { AccordionCollapseProps } from './AccordionCollapse';

代码：

import React, { Component } from 'react';

import { Button } from 'react-bootstrap';

class RestaurantList extends Component {

    render() {
        return (
            <div>
                <h1>RestaurantList</h1>
                <Button variant="primary">Submit</Button>
            </div>
        );
    }
}

export default RestaurantList;

Answer 1

我挣扎了一分钟，想知道到底发生了什么，直到我检查了package.json文件，并看到尽管编辑器正在使用3.7.5，但该版本仅为3.9.X。升级版本解决了该问题。试试这个npm install -g typescript@latest。您也可以在没有最新修饰符的情况下使用此命令npm update代替安装。

ReactBoostrap声明或预期的声明。 TS1128
