ng update fails with Yarn

[LaXiS96]

Command

update

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

<14 probably, not sure as it was a long time ago

Description

While updating a v15 application using Yarn (non-PnP), the ng update command fails with an unhelpful error.
The error claims there is no packageManager field in package.json, which is not true. Even if the field is really missing, ng update adds it but the next run will throw the same error.

The only workaround I found is to use npm to do the update (set packageManager: "[email protected]" in package.json, remove cli.packageManager from angular.json), and then revert to Yarn after the update.

It does not look like a Yarn issue, the behavior is the same with 3.4.1 or 4.2.2.

Minimal Reproduction

1. corepack enable
2. npx --package=@angular/cli@15 ng new ng15 --package-manager=yarn
3. add .yarnrc.yml with content: nodeLinker: node-modules
4. yarn install
5. ng update @angular/core@16 @angular/cli@16 --verbose --allow-dirty

Exception or Error

PS > ng update @angular/core@16 --verbose

! The local project doesn't define a 'packageManager' field. Corepack will now add one referencing [email protected]+sha512.a333bf9c2557d71f5ba87dd1446cde24bb9c35301ec29dd2baba577b3f9d1ab61348b66a1324de9088c40a996c5b9203794da8bf14cab9fae6a6eccc00cb8078.
