ERROR in src/app/app.module.ts(71,25): error TS2304: Cannot find name 'require'.

[dongzhouT]

this is my 'app.module.ts'
imports: [
BrowserModule,
FormsModule,
ChartModule.forRoot(require('highcharts'))
],
when i run 'ng serve',show the error->'ERROR in src/app/app.module.ts(71,25): error TS2304: Cannot find name 'require'.'
How can I do to fix it?

you can add declare var require: any to src/typings.d.ts, but it'll still fail when you try to build for production.

and there is no valid way for production / packaging? I am using ng-packagr to pack my modules and it fails because of this very unconvenient way with a require function inside forRoot:

ChartModule.forRoot(require('highcharts/highstock'))
