我正在开发角度应用程序,当我打开项目时,出现如下错误

尝试安装ngx-echarts
npm install echarts -S
npm install ngx-echarts -S
仍然出现上述错误
答案 0 :(得分:3)
将NgxEchartsModule
导入您的应用程序模块(或其他任何适当的角度模块):
具有动态导入功能
import { NgxEchartsModule } from 'ngx-echarts';
@NgModule({
imports: [
...,
NgxEchartsModule.forRoot({
echarts: () => import('echarts')
})
],
})
export class AppModule { }
OR
您也可以直接传递echart,这会减慢初始渲染的速度,因为它将整个echart加载到您的主包中。
import { NgxEchartsModule } from 'ngx-echarts';
import * as echarts from 'echarts';
@NgModule({
imports: [
NgxEchartsModule.forRoot({
echarts,
}),
],
})
export class AppModule {}
