Description

I have seem number of similar issues, but all says to use chmod 755 but this does not work in Windows. I wonder how to resolve this error in my system. I have checked adb devices and it shows the emulator and also the mobile device when running or connected. Both have Developer setting enabled.

I am getting following error precisely:

C:\Node_React_Apps\my-app-v2>react-native run-android

Scanning folders for symlinks in C:\Node_React_Apps\news-app-v2\node_modules (66ms)

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
https://facebook.github.io/react-native/docs/getting-started.html`

There is no such file in my my-app-v2/android/ directory as mentioned gradlew.bat, I also do not sure how to find any bug/log related to this issue which could help me to resolve the issue.

Some Background (if required)

I have detached my expo application, and only want to run it like this because I have integrated react-native-youtube library which requires detaching.
