我引用了element的组件，想改造下做成自己的UI库，打包后引入项目，npm run dev运行报了如下错误：
引入的包：node_modules/ipst/dist/ipst.js报错：
Uncaught TypeError: Cannot read property 'NODE_ENV' of undefined

打包后：
example/main.js,引用
import Vue from 'vue';
import App from './App';
import router from './router';
// dev
// import 'ele/theme-chalk/src/index.scss';
// import Ipst from '@/index.js';
// dist
import '../dist/static/ipst.css';
import Ipst from '../dist/ipst.js';
Vue.config.productionTip = false;
Vue.use(Ipst);
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
components: { App },
template: '<App/>'
});
控制台设置这个环境变量NODE_ENV='production'
