React native build failed in iOS - PhaseScriptExecution

Question

I am facing issue in react-native project. It's working fine in android but build failed in iOS version. I have already tried all possible solution, but didn't get any solution.

The main problem is PhaseScriptExecution.

Xcode version - 12.4

Mac OS version - 11.3 (Big Sur)

npm version - 7.10.0

react-native version - 0.64.0

react version - 17.0.1

For mode detail, i am attaching the screenshot.

Could you share the content at line 4 of the /Users/mmdev1/Library/.../FBReactNativeSpec.build/Script-99F08...sh file in the last screenshot? — MaartenDev

I was getting the same failure, and I have not been able to pinpoint exactly why this works, but in my package.json I changed

"scripts": {
    "ios": "react-native run-ios",
}

to

"scripts": {
    "ios": "unset PREFIX && react-native run-ios",
}

As I was seeing some issues regarding the PREFIX env variable when using Node Versioning Manager (nvm).
