我正在尝试在symfony / webpack-encore上使用jest和vuejs框架一起进行单元测试， 经过多次尝试，我仍然收到以下错误：

Jest encountered an unexpected token

This usually means that you are trying to import a file which Jest cannot parse,e.g. it's not plain JavaScript.

By default,if Jest sees a Babel config,it will use that to transform your files,ignoring "node_modules".


import {
       ^

SyntaxError: Unexpected token {

  20 | 
  21 | import * as THREE from 'three';
> 22 | import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader.js';
     | ^

这是我的.babelrc和package.json文件：

.babelrc：

{
  "presets": [
    "env",["env",{
      "modules": false
    }],"stage-2","vue"
  ],"plugins": ["transform-runtime","transform-es2015-modules-commonjs"],"env": {
    "test": {
      "presets":[
        ["es2015",{ "modules": false }],"vue","stage-2"
      ],"plugins": [
        "transform-es2015-modules-commonjs","dynamic-import-node"
      ]
    }
  }
}

package.json：

{
    "dependencies": {
        "bazinga-translator": "^2.6.6","bootstrap": "^4.3.1","driver.js": "^0.9.6","highcharts": "^6.2.0","jquery": "^3.3.1","jquery-ui": "^1.12.1","jquery.fancytree": "^2.30.2"

    }
}

我确实尝试了vue-cli，但在同一地点仍然遇到相同的错误！

谢谢
