When I created my Angular app and tried to add Scully for SEO static it just silently failed without creating:
- scully.my-blog{{your blog name here}}.config.ts
- scully folder in the root of the app with tsconfig.json and plugins folder with plugin.ts file
I used the command as in the Scully documentation: https://scully.io/docs/learn/overview/
ng add @scullyio/init

The problem was here that there was not defined the name of the project as the option of this CLI command.
The right solutions is here:
ng add @scullyio/init --project=my-blog
where my-blog is the name of my project
And yes, there was yet several npm issues - I have an Angular app of 14 version but angular/animations needs to be "@angular/animations": "^12.2.16" - you need to change the version in your package.json, and it doesn't work until I run
npm install --legacy-peer-deps.
