我正在按照https://github.com/xiaodongliang/forgeviewer_embed_in_powerbi_report上的教程在 PowerBi 中创建自定义视觉对象。为了可视化3d模型作者建议安装2.5.0版本的可视化工具，否则无法使用

npm i -g powerbi-visuals-tools@2.5.0

（我实际上尝试了安装 3.2.0 而不是 2.5.0 的相同过程，实际上它不起作用，自定义视觉效果保持空白而不是向我显示模型，所以我正在使用 2.5.0 重新启动该过程api版本）

运行命令“pbiviz start”它给了我这个错误：

PS C:\Users\Gian Marco Manfredi\circlecard> pbiviz start
 info   Building visual...
 error  LESS  style/visual.less :  The "data" argument must be of type string or an instance of Buffer, TypedArray, or DataView. Received undefined

visual.less 是

p {
    font-size: 20px;
    font-weight: bold;
    em {
        background: yellow;
        padding: 5px;
        
    }
}

pbiviz.json 是

{
  "visual": {
    "name": "circleCard",
    "displayName": "CircleCard",
    "guid": "circleCardA2677EDA579643169880D5D3DF0E2A32",
    "visualClassName": "Visual",
    "version": "1.0.0",
    "description": "",
    "supportUrl": "",
    "gitHubUrl": ""
  },
  "apiVersion": "2.5.0",
  "author": {
    "name": "",
    "email": ""
  },
  "assets": {
    "icon": "assets/icon.png"
  },
  "externalJS": [
    "node_modules/powerbi-visuals-utils-dataviewutils/lib/index.js"
  ],
  "style": "style/visual.less",
  "capabilities": "capabilities.json",
  "dependencies": "dependencies.json",
  "stringResources": []
}

我希望有人可以帮助我

谢谢！
