Desired functionality

I just updated to 7.0.0 using command ng update @angular/cli @angular/core.
But ng-packagr was not updated and also there was problem with tsickle versioning.
Now since ng-packagr is used for generating library it should be updated as well.

Mention any other details that might be useful

Any temporary workaround for this?

[alexeagle]

tsickle was removed as a dependency from Angular v7
But we forgot to remove it from ng-packagr and build-ng-packagr. See https://github.com/angular/angular-cli/blob/master/packages/schematics/angular/library/index.ts#L115

Note, this means that libraries published by CLI will no longer be compatible with Closure Compiler downstream consumption by default. To build a library that works with Closure Compiler, you'll have to manually add the tsickle dependency, and get on a version of TypeScript that works with tsickle, which may lag the version used/required by Angular.
