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
➤ YN0000: · Failed with errors in 1m 5s
node:internal/process/promises:389
      new UnhandledPromiseRejection(reason);
      ^

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>".

Node.js v20.17.0

The log contains the following:

# This file contains the result of Yarn building a package (detox@virtual:b9d026221b6ccf869e6d11f2b48ce0b8c57b8019f0c9d219cace198e95e746647dd8655694a089c347671f2cf32e0f278e26b7a94b2cc75061efff0c4e6ae31b#npm:20.18.1)

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

Required package: react-native (via "react-native/package.json")
