This error exposed when I used ngx-echarts in angular7 and compiled by rollup. The error messages are follows:

` [!] Error: 'init' is not exported by node_modules\echarts\index.js https://rollupjs.org/guide/en#error-name-is-not-exported-by-module- node_modules\ngx-echarts\fesm5\ngx-echarts.js (3:9)

1: import { of, EMPTY, fromEvent, Observable } from 'rxjs';

2: import { Directive, ElementRef, EventEmitter, Input, NgZone, Output, NgModule } from '@angular/core';

3: import { init } from 'echarts';

4: import { debounceTime, switchMap } from 'rxjs/operators';
