Appears in the NgModule.imports of AppModule, but could not be resolved to an NgModule class in angular 8
restart your server...
terminate server for windows
ctrl + C
start again
ng serve
I had the same issue.
I was going through comments here https://github.com/angular/angular/issues/35399 for solution.
I simple ran ng serve --prod
and the error was gone. After that I even ran ng serve
.
Other solutions proposed are
- Ensure that the tsconfig.json of your library has set "importHelpers": true
- Add
"enableIvy": false
to compilerOptions in tsconfig.app.json
Simply restart the server (press ctrl+c on the prompt) and then, run ng serve again.
I had the same issue. Then I realized that previously I've some changes in app.module.ts Every time you made changes in app.module.ts remember restart the server process.
