Description
@johnpapa tried to update https://github.com/johnpapa/angular-event-view-cli to version 8 but ran into some problems related to peer dependencies.
You can reproduce the starting state by following these commands:
git clone https://github.com/johnpapa/angular-event-view-cli
cd angular-event-view-cli
git checkout 437ebea5b099a7a8e24bbcd0ed14938b3183a1f5
At this point running npm i will show some peer dependency warnings:

$ npm i

These warnings say that angular-in-memory-web-api and codelyzer do not support Angular version 7, which is currently used on the project.
Trying to update to 8 at this stage will not work:

$ ng update @angular/core @angular/cli

Incompatible peer dependencies found. See above.
To enable the update, all peerDependency for Angular must be resolved prior to the update.

The update would also have ran if --force was used, but the user was never informed of that. Perhaps if we had mentioned that on the original error message, it would have been easier from the start. But even better than that would be to also explain the peer dependency problem better.
