_Original issue by @JessimZ on [2019-08-27T15:37:12Z](https://github.com/ionic-team/ionic/issues/19201)_

Hello,

We use Ionic for our company, KoZi Technology, my colleague is having a problem that I don't personally have.
He can't launch our application via the command "ionic serve", there is a problem with the npm library. Despite the fact that it has uninstalled and reinstalled it, the problem persists.

He used the command "ionic doctor check" and this is what appears :

[ERROR] Error while checking default-cordova-bundle-id-used:

Thank you in advance for helping us, we remain available by email.

Comece reproduzindo a falha com `ionic serve` e `ionic doctor check`, usando os erros relatados de `@ionic/cli-framework/errors.js` e `ionic/lib/errors.js` como pontos de entrada. Verifique os detalhes do ambiente e do projeto necessários para acionar `default-cordova-bundle-id-used` e `unsaved-cordova-platforms`; considera-se concluído quando as verificações forem concluídas sem esses erros e `ionic serve` for iniciado.
