为什么 react-sortable-hoc 基本示例无法使用 typescript 编译？

Question

import React, {Component} from 'react';
import {render} from 'react-dom';
import {SortableContainer, SortableElement, arrayMove} from 'react-sortable-hoc';

const SortableItem = SortableElement(({value}) =>
  <li>{value}</li>
);

const SortableList = SortableContainer(({items}) => {
  return (
    <ul>
      {items.map((value, index) => (
        <SortableItem key={`item-${index}`} index={index} value={value} />
      ))}
    </ul>
  );
});

class SortableComponent extends Component {
  state = {
    items: ['Item 1', 'Item 2', 'Item 3', 'Item 4', 'Item 5', 'Item 6'],
  };
  onSortEnd = ({oldIndex, newIndex}) => {
    this.setState({
      items: arrayMove(this.state.items, oldIndex, newIndex),
    });
  };
  render() {
    return <SortableList items={this.state.items} onSortEnd={this.onSortEnd} />;
  }
}

render(<SortableComponent/>, document.getElementById('root'));

我不得不稍微修改上面的代码以适应 typescript 导入语法，下面的屏幕截图显示了我不确定如何修复的错误：

上面截图对应的代码如下：

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import {SortableContainer, SortableElement, arrayMove} from 'react-sortable-hoc';

const SortableItem = SortableElement(({value}) =>
  <li>{value}</li>
);

const SortableList = SortableContainer(({items}) => {
  return (
    <ul>
      {items.map((value, index) => (
        <SortableItem key={`item-${index}`} index={index} value={value} />
      ))}
    </ul>
  );
});

class SortableComponent extends React.Component {
  state = {
    items: ['Item 1', 'Item 2', 'Item 3', 'Item 4', 'Item 5', 'Item 6'],
  };
  onSortEnd = ({oldIndex, newIndex}) => {
    this.setState({
      items: arrayMove(this.state.items, oldIndex, newIndex),
    });
  };
  render() {
    return <SortableList items={this.state.items} onSortEnd={this.onSortEnd} />;
  }
}

ReactDOM.render(<SortableComponent/>, document.getElementById('root'));

我不知道如何解析这些错误的错误文本。由于该项目在 GitHub 上有 5k+ 星，我假设我有某种配置问题，但我似乎无法弄清楚它是什么。

这是剩下的两个错误：

1.

[ts] Property 'items' does not exist on type 'IntrinsicAttributes & IntrinsicClassAttributes

2.

[ts] Property 'value' does not exist on type 'IntrinsicAttributes & IntrinsicClassAttributes

错误文本读起来好像没有正确提取组件包装语法，但我自己不熟悉这种语法，所以我不确定我是否正确诊断了问题或如何修复它.

感谢您的帮助。

文档中基本示例中的代码是JavaScript。

这是转换为 TypeScript 的基本示例：

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { arrayMove, SortableContainer, SortableElement } from 'react-sortable-hoc';

const SortableItem = SortableElement(({value}: {value: string}) =>
  <li>{value}</li>
);

const SortableList = SortableContainer(({items}: {items: string[]}) => {
  return (
    <ul>
      {items.map((value, index) => (
        <SortableItem key={`item-${index}`} index={index} value={value} />
      ))}
    </ul>
  );
});

class SortableComponent extends React.Component<{}, {items: string[]}> {
  constructor(props: {}) {
    super(props);
    this.state = {
      items: ['Item 1', 'Item 2', 'Item 3', 'Item 4', 'Item 5', 'Item 6']
    }
  }
  public render() {
    return <SortableList items={this.state.items} onSortEnd={this.onSortEnd} />;
  }
  private onSortEnd = ({oldIndex, newIndex}: {oldIndex: number, newIndex: number}) => {
    this.setState({
      items: arrayMove(this.state.items, oldIndex, newIndex),
    });
  };
}

ReactDOM.render(<SortableComponent/>, document.getElementById('root'));

如果有人需要我正在使用带有 ts 的 mui 的可选拖动手柄的代码，我还包含了 'packageData' 的示例，如果您需要查看界面，请告诉我？

import React, { Component } from 'react';
import {
  SortableContainer,
  SortableElement,
  SortableHandle
} from 'react-sortable-hoc';
import arrayMove from 'array-move';
import { packageData } from '../../data/packagesData';
import { List } from '@material-ui/core';
import ListItem from '../../components/UI/ListItem/ListItem';
import EditIcon from '@material-ui/icons/DragIndicator';
import { PackageResAdmin } from '../../ts/apiTs';

const DragHandle = SortableHandle(() => <EditIcon />);

const SortableItem = SortableElement(
  ({ id, galleryId, translations }: PackageResAdmin) => (
    <ListItem
      id={id}
      children={<DragHandle />}
      galleryId={galleryId}
      translations={translations}
    />
  )
);
const SortableContainerWrapper = SortableContainer(
  ({ children }: { children: {}[] }) => {
    return <List>{children}</List>;
  }
);

class DndComponent extends Component {
  state = { packageData };

  private onSortEnd = ({
    oldIndex,
    newIndex
  }: {
    oldIndex: number;
    newIndex: number;
  }) => {
    this.setState({
      packageData: arrayMove(this.state.packageData, oldIndex, newIndex)
    });
  };

  render() {
    console.log(this.state);
    return (
      <SortableContainerWrapper onSortEnd={this.onSortEnd} useDragHandle>
        {this.state.packageData.map((res, index) => (
          <SortableItem
            key={`item-${index}`}
            index={index}
            id={res.id}
            galleryId={res.galleryId}
            translations={res.translations}
          />
        ))}
      </SortableContainerWrapper>
    );
  }
}

export default DndComponent;


export const packageData: PackageResAdmin[] = [


{
    galleryId: 1,
    id: 1,
    translations: {
      [Language.CS]: {
        additionalInfo: 'additionalInfo',
        content: 'content',
        language: Language.CS,
        parentId: 1,
        title: 'eden'
      },
      [Language.EN]: {
        additionalInfo: 'additionalInfo',
        content: 'content',
        language: Language.EN,
        parentId: 1,
        title: 'one'
      }
    }
  },
  {
    galleryId: 1,
    id: 2,
    translations: {
      [Language.CS]: {
        additionalInfo: 'additionalInfo',
        content: 'content',
        language: Language.CS,

];
