ng add @nestjs/ng-universal fails with ✖ Packages installation failed, see above.

Expected behavior

NestJS is added to Angular 15 project.

ng new webapp
cd webapp
ng add @nestjs/ng-universal

What is the motivation / use case for changing the behavior?

Use the framework

Environment

Nest version: * (latest) and 6.0.1  (`ng add @nestjs/ng-universal` automatically picks 6.0.1 version for me)

Any workaround for the time being?

Had the same issue, did some investigation and after few hours seems like there is no support for Angular 15 which makes me quite sad considering Angular 15 has been out for some time now. Only workaround to this issue is to use latest Angular 14 deps and it will work with latest version of @nest/ng-universal... Update the version, please!

Hey folks, till the time the PR from bartlomiejgawel is not merged, you can use this NPM package: https://www.npmjs.com/package/ng-universal-15

This package supports Angular 15.

PS. I used the PR of bartlomiejgawel and published my own package as a quick fix ;)

I think this has been fixed in 0.8.0, I've also created a PR with this fix, and one other (bug crashed Angular development building process because of incorrect cache path) that has been done in said version, though PR hasn't been merged. Angular has been updated to 15 (from 14), but in some cases you may have to use the --force parameter to get around the possible minor version of Angular mismatch. It works for me in a NX workspace with Nest.js and Angular. I think there was no need for a temporary fork-y workaround, but also had same idea to make well-maintained version of this lib pre-0.8.0.
