what is the version of angular are you using?. the package supports systemjs. IF you are using Angular 4+ please use npmjs.com/package/angular2-toaster — Suresh Kumar Ariya

This is basically due to any sort of compilation error occurs on building the angular application. Make sure that the npm console is clean. To do this, just run the command npm start from VSCode npm console.

This will be basically an error in your Angular application. You can check "Output" window in Visual studio, which displays the exact error message.

I solved this with ngx-toastr library what you need to do is to update your angular application to latest version(from ClienApp folder). Use this Link.

After you do update add ngx-toastr like they explain on the website and you will be able to run the application.
Or you can just install older version of ngx-toasty with this command and it will work.

npm install [email protected] --save

I was facing the same problem.You need to do a little change in app.module.ts file mostly available in (..\ClientApp\src\app\app.module.ts).Just remove the deleted components and declarations from app.module.ts
