I have a project which uses npm link to pull in a shared library "@ teachtown/shared"^, which is TS source code, not transpiled / packaged as JS. The intention is that this library will be used in multiple projects.

^ space after "@" so that github doesn't try to parse as user/project

I'm trying to upgrade the consuming project, Angular 5.2.5 => 6, following the instructions provided on https://update.angular.io/.

I reached the following steps, and got an error:

npm install -g @angular/cli
npm install @angular/cli
ng update @angular/cli

> Not found : @teachtown/shared

(Aside: I had to update the second command to npm install @angular/cli --save-dev for it to properly update CLI in my project.)

Note that @ teachtown/shared does exist:

$ ls node_modules/@teachtown
> shared

Repro steps

Desired behavior

One of the following:

Angular CLI provides support for shared projects in source form.
Update process recognizes the shared project (by detection of package.json?) and offers option to include as / convert to a library, since CLI now supports ng generate library.
