Здравствуйте!
Я разрабатывал приложение и на следующий день мне выходит эта ошибка:

Invariant Violation: "main" has not been registered. This can happen if:
* Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.
* A module failed to load due to an error and `AppRegistry.registerComponent` wasn't called.

Для тестирования я использую expo
Я пытался обновить expo cli и переустанавливал mode_nodules но это не помогло
Подскажите пожалуйста как решить эту проблему

первое же сообщение ReferenceError: Can't find variable: StyleSheet
вы где то используете StyleSheet но не импортировали его

Роман Александрович, спасибо что ответили, но дело не в этом. Я сам не понял как, но с помощью манипуляций с пакетами решил проблему
