Reproduce npx create-codeceptjs . --use-yarn in a Vite/SWC React project and inspect the generated package setup and Yarn postinstall output, especially the Detox error about react-native. Done means the installer completes for a plain React web project without the unhandled rejection or incompatible React Native dependency failure.
Written by the indexing model from the issue text.
Description
I am using npx create-codeceptjs . --use-yarn in a React project created with Vite using SWC. I had barely added a couple of dependencies. After that I ran the aforementioned code and I received the following error:
➤ YN0000: └ Completed in 29s 664ms

UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason "#<Object>".

The log contains the following:

Error: detox tried to access react-native, but it isn't declared in its dependencies; this makes the require call ambiguous and unsound.
