按需引入 Element “.babelrc”的修改

原来的样子

修改后

如果还没有下载过babel-preset-es2015包记得在修改后去npm install下

 附上没格式的代码

{

"presets": [

["es2015", { "modules": false }],

"stage-2"

],

"plugins":

["transform-runtime",["component", [

{

"libraryName": "element-ui",

"styleLibraryName": "theme-default"

}

]]],

"comments": false,

"env": {

"test": {

"presets": ["env", "stage-2"],

"plugins": [ "istanbul" ]

}

}

}
