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update @angular/core@11 @angular/cli@11 --force I'm getting this error : The installed Angular CLI version is outdated. Installing a temporary Angular CLI versioned 11.2.18 to perform the update. Installing packages for tooling via npm. Installed packages for tooling via npm.

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 ? Continue reading...
