Impossible to install @casl/angular with angular 13

[Chachuke]

Hi,

So i've got an ionic-angular project where i need to use casl.

I see on this page that i have to install the 7.x version of casl/angular
https://github.com/stalniy/casl/blob/master/packages/casl-angular/CHANGELOG.md

So, I tried, to install casl but unfortunatly i can't.

here is what i got as error :
`npm install @casl/[email protected]
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree

Here is my ionic info :

So here i understand that @casl/angular need rxjs in version 7.5.5 and angular in version 13.0.0, the problem is that i can't update to version 7 of rxjs nor to version 14 of angular because of some dependencies used in the project...

is there something i can do to install it without changing angular or rxjs version ?

I managed to install it by downgrading to angular 12, but that's not what i want.

I see, angular 13 supports both versions "rxjs": "^6.5.3 || ^7.4.0" but in casl only 1 specified. If it's still an issue, I'd recommend to ignore this (use --force or overrides in package.json). Since casl doesn't use anything fancy from rxjs
