Update to angular 5 throws Version of @angular/compiler-cli needs to be 2.3.1 or greater. Current version is 5.1.0

Question

I want to upgrade angular 4 from asp.net core2 to angular 5 (latest one)

I did this steps:

1. dotnet new angular

2. npm install @angular/animations@latest @angular/common@latest @angular/compiler@latest @angular/compiler-cli@latest @angular/core@latest @angular/forms@latest @angular/http@latest @angular/platform-browser@latest @angular/platform-browser-dynamic@latest @angular/platform-server@latest @angular/router@latest rxjs@latest --save
   npm install [email protected] --save-exact

3. npm install (to make sure)

4. dotnet run

and it produce error : (Version of @angular/compiler-cli needs to be 2.3.1 or greater. Current version is "5.1.0".) and i have no idea how to fix it.
