Repro steps

We have been using yarn for some time now and it has been working fine… but now with “ng update” it feels as yarn.lock file is not used properly?

Running ng update tells me @angular/cli needs update… then running ng update @angular/cli does nothing but tell me that all looks good… ?

To get rid of this issue I can just run npm install to generate the package-lock.json file and then run ng update @angular/cli and it works…

Using the lock file would be a potential optimization for installed package discovery, not a fix for any of the issues discussed in this thread.

@clydin No, npm is not installed. I manually updated @angular/cli with:

yarn global remove @angular/cli
yarn remove @angular/cli
yarn global add @angular/cli
yarn add @angular/cli --dev

Output from ng --version:
