Package '@angular/cli' is not a dependency

Issue

I am getting the following error when I try to run the command

ng update @angular/cli @angular/core --allow-dirty

Repository is not clean.  Update changes will be mixed with pre-existing changes.
Using package manager: 'npm'
Collecting installed dependencies...
Found 28 dependencies.
Package '@angular/cli' is not a dependency.

Solution

First commit all your changes to the repo and then try following commands.

npm i -g @angular/cli@8.0.0

and

ng update --all --force
