                  Package "@angular/compiler-cli" has an incompatible peer dependency to "typescript" (requires ">=2.7.2 <2.8", would install "2.9.1").

To have a successful message.

I also ran into this issue and trying to install typescript 2.8 installs version 2.8.4 which also gives an error.

Also seeing this when _migrating an older project_.

Hi @aphexddb,

Unfortunately, this one comes down as a feature. ng update --all will still validate that all dependencies are compatible with each others, but typescript's latest is 2.9, which isn't compatible with Angular's compiler. You can use ng update --all --force to force the update, or just update dependencies one at a time.

Now there's a case to be made that --all should be smarter and only update compatible versions. I think we need a feature in the future (e.g. --smart) that would do that, but in the meantime this is the best that makes sense.

Closing this as working as intended.

Hi @hansl,

In a new project, if we run just ng update is says that there is nothing to update, but if we use the flag --all it gives this "incompatible peer dependency" error. It looks contradictory or at least confusing for me. Shouldn't the --all flag just execute what is at the ng update list? And do nothing if it is empty?

Any news on this? I installed Typescript 3.1.6 as a workaround and have no problems.
