項目是vue-cli自動生成的，所以package.json中已經引入babel也應該可以解析es6語法，可是貌似報錯是不能解析...擴展符?或者是其他什么原因嗎?Add.vue報錯部分代碼:import {mapActions, mapMutations} from 'vuex'   export default{     methods: {       save(){         this.saveArticle()         },       ...mapActions(['saveArticle']),       ...mapMutations(['SET_ARTICLE'])            }安裝依賴如下:  "devDependencies": {    "autoprefixer": "^6.5.3",    "babel-core": "^6.0.0",    "babel-loader": "^6.0.0",    "babel-preset-es2015": "^6.0.0",    "babel-plugin-transform-object-rest-spread": "^6.19.0",    "cross-env": "^3.0.0",    "css-loader": "^0.25.0",    "file-loader": "^0.9.0",    "url-loader": "^0.5.7",    "vue-loader": "^10.0.0",    "vue-resource": "^1.0.3",    "vue-router": "^2.0.1",    "vue-template-compiler": "^2.1.0",    "vuex": "^2.0.0",    "webpack": "^2.1.0-beta.25",    "webpack-dev-server": "^2.1.0-beta.0"  }控制臺報錯:
