// app.json

"tfjsPlugin": {

      "version": "0.1.0",

      "provider": "wx6afed118d9e81df9"

    }

// package.json

"dependencies": {

    "[[@tensorflow](/user/tensorflow)-models](/user/tensorflow-models)/speech-commands": "^0.4.2",

    "[@tensorflow](/user/tensorflow)/tfjs": "^2.0.1",

    "fetch-wechat": "0.0.3"

  }

// app.js

var tf = require('[@tensorflow](/user/tensorflow)/tfjs');

// 运行报错

Cannot delete property ‘toString’ of function () { [native code] }

猜测与 “跳过ES6转ES5处理” 没有关系，因为我自己把代码转到ES5也还是报同样错，难道是用到ES6特性了？

不用分包是因为'[[@tensorflow](/user/tensorflow)-models](/user/tensorflow-models)/speech-commands'这个模型引入时提示需要[@tensorflow](/user/tensorflow)/tfjs.js

求解答！！！
