语法错误_无法使用Jest测试Vue组件：语法错误意外的标识符

使用@ vue / cli @ 3.6.3创建项目。这是package.json

"scripts":
"serve": "vue-cli-service serve",
"build": "vue-cli-service build",
"lint": "vue-cli-service lint",
"test": "npm run lint && npm run test:unit",
"test:unit": "jest --no-cache"
,
"dependencies":
"core-js": "^2.6.5",
"vue": "^2.6.10"
,
"devDependencies":
"@vue/cli-plugin-babel": "^3.6.0",
"@vue/cli-plugin-eslint": "^3.6.0",
"@vue/cli-service": "^3.6.0",
"@vue/eslint-config-standard": "^4.0.0",
"babel-eslint": "^10.0.1",
"babel-jest": "^24.7.1",
"eslint": "^5.16.0",
"eslint-plugin-vue": "^5.0.0",
"jest": "^24.7.1",
"vue-jest": "^3.0.4",
"vue-template-compiler": "^2.5.21"
,
"jest":
"transform":
"^.+\\.js$": "babel-jest",
"^.+\\.vue$": "vue-jest"



这是我的考验

import Item from '../Item.vue'
describe('Item.vue', () =>
test('sanity test', () =>
console.log(Item)
)
)


使用组件Item.vue

这就是结果

我在import语句中得到错误。我认为这将通过使用开关变换器来处理，但事实并非如此。通过测试还需要添加什么？项目网址是this。
