Hi @billfranklin
It's normal behavior.
Latest @angular/angular-cli:7.1.0 is shipped with typescript:3.1.6 and supports only patches: typescript < 3.2.
Newest typescript:3.2.1 increments minor version (typescript:3.1.6 in @angular/angular-cli:7.1.0) and should not have breaking changes but it's safer to limit typescript updates to patches.

See https://semver.org/

It's normal behavior for ng update to throw errors? Seems like bad design to me...

This is the error generated while it is trying to update the compiler-cli...should be fixed to NOT try to install an incompatible dependency

[Binero]

@KrzysztofKarol This also makes it impossible to install "@angular/cli" with the latest version of "@angular/core". I don't see how that's normal behaviour. Surely the latest version of the CLI should be compatible with the latest version of the framework?

[KrzysztofKarol]

@billfranklin Sorry, I mistook ng-update with https://www.npmjs.com/package/npm-check-updates.
Yes, this is a bug. ng-update should update typescript to latest supported version.
But I don't think it will be resolved soon: #11138 (comment).

@dalu You can do:
ng update --all --force
and then
npm i typescript@3.1.6 (or even better: npm i typescript@"<3.2")

@angular/service-worker wrong peerDependency in 7.1.0 angular/angular#27233 is referencing back to this issue!

[rakishii13]

Will this be updated soon?

[FrancescoBorzi]

same issue here

[JosepAlacid]

rakishii13, this is #13123

and references back here...

[avatsaev]

this has always been an issue, it's not even new.

[rogerfar]

Can't ng update just try to install the latest compatible version of TypeScript? Now I have to go through each package and check if it's compatible with Angular because it errors out right away.
