  The error "Specified module 'app' does not exist" occurs because the Angular CLI cannot find a module named app when you use the --module app option. In Angular, the --module option expects the name of an existing module file (e.g., app.module.ts), not just app.

  Solution

  1. Use the Correct Module Path
     • Instead of --module app, specify the full path to your root module file, usually app.module.ts:

  yarn ng generate module author --module src/app/app.module.ts --routing --route authors
  

  • This tells Angular CLI to import the new module into src/app/app.module.ts.

  2. Verify Module File Exists

     • Ensure that src/app/app.module.ts exists in your project. If your main module has a different name or location, adjust the path accordingly.

  3. Reference from Official Tutorial

     • The official ABP Book Store tutorial uses the following command:

  yarn ng generate module author --module app --routing --route authors
  

  • However, if your project structure is different or the CLI cannot resolve app, always use the explicit path as shown above.

  Example

  yarn ng generate module author --module src/app/app.module.ts --routing --route authors
  

  This will correctly generate the author module and update your app.module.ts with the new import.
