I'm updating my angular app by following the angular update guide and I'm stuck with an error of peer dependencies.
First I update from angular 8 to 9 but there was still a peer dependency error. So I use this command with --force argument :
cmd /C "set "NG_DISABLE_VERSION_CHECK=1" && npx @angular/cli@9 update @angular/cli@9 @angular/core@9" --force
And it works !
Then from Angular 9 to 10, same method with
npx @angular/cli@10 update @angular/core@10 @angular/cli@10 --force
And it works, too. Now I want to continue to Angular 11, 12 and 13 but when I use this command :
npx @angular/cli@11 update @angular/core@11 @angular/cli@11 --force
I'm getting this error :
The installed Angular CLI version is outdated.

I know that was a bad idea to use --force argument, but prefer to solve peer dependencies once angular is updated, not on each version.
Please, does anyone got an idea ?
Found it ! That was a problem with my node version. I was using v16.9 and install node v14.19 solve my problem.
I took the oportunity to install windows-nvm to be abble to manage many node version.
