Upgrading library projects to Angular 12?

I'm trying to run this on library projects / projects that have a workspace:

ng update @angular/core @angular/cli @angular/material

It worked on one project, however for the rest I always get:

Cannot locate bin for temporary package: @angular/cli

Any ideas?

Solution

I had the same issue after upgrading to ng 12.
We use nrwl/nx which makes everything even more tricky...

Workaround

install angular cli globally:
npm install -g @angular/cli@latest
now get the path of this installation, e.g. in a new git-bash terminal (outside of my projects):
which ng
- will print e.g. /c/Program Files/nodejs/ng
  this should be the latest version that we have just installed
- execute "/c/Program Files/nodejs/ng" --version to make sure that you have the newest version (12.0.3 in my case
now I can run my updates: e.g. "/c/Program Files/nodejs/ng" update @angular/flex-layout @angular/cdk @angular/material
