Upgrading Angular from 9 to 10 Error: Package '-e' is not a dependency

Question

has anybody here bumped into the following issue when updating an angular app from 9 to 10.

"Package '-e' is not a dependency."

That happens when running ng update @angular/core@10 @angular/cli@10

Did some googling but there's not a single result out there that matches my issue (that's gotta be a first)

Answer 1

Make sure you aren't using '-force'. Instead, use the correct '--force' parameter.

Answer 2

After taking backup:

try to update CLI first

npm i @angular/cli@10

then core

ng update @angular/core@10

or

ng update @angular/core@10 --force
