Mars3d引用单个示例文件WeiVectorTileLayer.js报错的解决办法

参考文档修改文件后，发现依然报错：

Mars3d单独引用示例文件教程_3d文件示例_绵绵-火星科技的博客-CSDN博客

具体报错截图：

 看报错是： CesiumVectorTile.js里的错误，进去看看错误行，是不是缺cesium

  // if (typeof exports === "object" && typeof module === "object") module.exports = factory(require("mars3d-cesium"), require("@turf/turf"))

  // else if (typeof define === "function" && define.amd) define("CesiumVectorTile", ["mars3d-cesium", "@turf/turf"], factory)

  // else if (typeof exports === "object") exports["CesiumVectorTile"] = factory(require("mars3d-cesium"), require("@turf/turf"))

  // else root["CesiumVectorTile"] = factory(root["Cesium"], root["turf"])

以上面注释的代码中没有请求到@turf/turf库的原因

CesiumVectorTile.js文件修改了导入设置：

import * as Cesium from "mars3d-cesium"

import * as turf from "@turf/turf"

let CesiumVectorTile

;(function webpackUniversalModuleDefinition(root, factory) {

    CesiumVectorTile = factory(Cesium, turf)

CesiumVectorTile.js文件的末尾修改配置：

export { CesiumVectorTile }

WeiVectorTileLayer.js 文件的配置：

//按mars3d规范，将CesiumVectorTile封装下

import * as mars3d from "mars3d"

import {CesiumVectorTile} from './CesiumVectorTile'

export   class WeiVectorTileLayer extends mars3d.layer.BaseTileLayer {

    //构建ImageryProvider

    _createImageryProvider(options) {

      return createImageryProvider(options)

    }

  }

  function createImageryProvider(options) {

    return new CesiumVectorTile.VectorTileImageryProvider(options) //CesiumVectorTile.js中

  }

  WeiVectorTileLayer.createImageryProvider = createImageryProvider

  //注册下

  const layerType = "weiVectorTile" //图层类型

  mars3d.LayerUtil.register(layerType, WeiVectorTileLayer)

  mars3d.LayerUtil.registerImageryProvider(layerType, createImageryProvider)

  //对外接口

  mars3d.layer.WeiVectorTileLayer = WeiVectorTileLayer
