SPFX React -Basic Webpart 中的数据版本错误

Data version error in SPFX React -Basic Webpart

我刚刚创建了一个带有反应的基本 spfx webpart,但出现以下错误:

{ "资源": "/c:/Node_Dev/CRUD_React/src/webparts/crudReact001/CrudReact001WebPart.ts", “所有者”:“打字稿”, “代码”:“2611”, “严重性”:8, "message": "'dataVersion' 在 class 'BaseClientSideWebPart' 中定义为 属性,但在 'CrudReact001WebPart' 中作为访问器被覆盖。", “来源”:“TS”, “开始行号”:35, “开始列”:17, “结束行号”:35, “结束列”:28 }

我的代码:

import * as React from 'react';
import * as ReactDom from 'react-dom';
import { Version } from '@microsoft/sp-core-library';
import {
  IPropertyPaneConfiguration,
  PropertyPaneTextField
} from '@microsoft/sp-property-pane';
import { BaseClientSideWebPart } from '@microsoft/sp-webpart-base';

import * as strings from 'CrudReact001WebPartStrings';
import CrudReact001 from './components/CrudReact001';
import { ICrudReact001Props } from './components/ICrudReact001Props';

export interface ICrudReact001WebPartProps {
  description: string;
}

export default class CrudReact001WebPart extends BaseClientSideWebPart<ICrudReact001WebPartProps> {

  public render(): void {
    const element: React.ReactElement<ICrudReact001Props> = React.createElement(
      CrudReact001,
      {
        description: this.properties.description
      }
    );

    ReactDom.render(element, this.domElement);
  }

  protected onDispose(): void {
    ReactDom.unmountComponentAtNode(this.domElement);
  }

  protected get dataVersion(): Version {
    return Version.parse('1.0');
  }

  protected getPropertyPaneConfiguration(): IPropertyPaneConfiguration {
    return {
      pages: [
        {
          header: {
            description: strings.PropertyPaneDescription
          },
          groups: [
            {
              groupName: strings.BasicGroupName,
              groupFields: [
                PropertyPaneTextField('description', {
                  label: strings.DescriptionFieldLabel
                })
              ]
            }
          ]
        }
      ]
    };
  }
}

您可以删除'datavaersion'方法,它与SPFx v1.10兼容,但在安装V1.11时会出错。

建议的解决方案是:

  1. 使用 TypeScript 的 Workspace 版本 (3.3.4000) 而不是 VS Code 的较新版本
  2. 装饰方法 // @ts-ignore
