Specify the module using the --module parameter. For example, if the main module is app.module.ts, run this: ng g c new-component --module app Or if you are in an other directory then ng g c component-name --module ../
ng g c new-component --module app //Or if you are in an other directory then ng g c component-name --module ../
ng g c componentName --module app (if your module is app)
