cnpm i babel-plugin-component -D
然后修改.babelrc：
{
"presets": [["es2015", { "modules": false }]],
"plugins": [
["component",
[{
"libraryName": "mint-ui",
"style": true
},
{
"libraryName": "element-ui",
"styleLibraryName": "theme-chalk"
}]
]
]
}当然这样写还不够，会报错，所以我们还需安装：cnpm install babel-preset-es2015 --save-dev
第二种方法
再需安装一个： npm install babel-plugin-import --save-dev
{
"presets": [
["env", {
"modules": false,
"targets": {
"browsers": ["> 1%", "last 2 versions", "not ie <= 8"]
}
}],
"stage-2"
],
"plugins": ["transform-vue-jsx", "transform-runtime",
["component", {
"libraryName": "mint-ui",
"style":true
}],
["import",
{
"libraryName": "element-ui",
"styleLibraryName": "theme-chalk"
}
]
]
}import Vue from 'vue'
import App from './App.vue'
import Element from 'element-ui'
import {Button } from 'mint-ui/lib/button';
Vue.component(Button.name, Button);
Vue.use(Element)
