Getting Command PhaseScriptExecution failed with a nonzero exit code while running in iOS

[Shahanshah-TA]

Trying to run a RN app to iOS. If I build a bare-bones RN app I can get this running in a simulator without issue. The moment I add nodejs-mobile the application no longer compiles.

Versions:
NodeJS 20.12.2 (I have also tried with Node 18.20.2 & 16.20.2)
RN 0.71.8
nodejs-mobile 18.17.7 (I have also tried with 18.17.6)
iOS Simulator 17.4

Install process

npx react-native init projectName
cd projectName
npm start > i (Install cocoapods)
(Confirm the installation operates on iOS Simulator, exit Metro server)
npm i nodejs-mobile-react-native
cd ios
pod install
cd ..
npm start > i (build new iOS app, hangs, build logs below)

I have tried deleting the DerivedData, /ios/pod & pod install, /ios/build, removing the /node_modules & npm install, deleting the apps on the simulator. I have also tried downgrading RN and nodejs-mobile. Restarting the Mac, restarting Terminal.

The moment I add nodejs-mobile the application no longer compiles.

Please share the errors you see, they give vital hints on what's going wrong. Without knowing what's wrong, it's hard to fix something.

Fixed it. Issue was it was using some other node version (I guess 20+). I created .xcode.env.local and added

. "$(brew --prefix nvm)/nvm.sh"
nvm use 18

Now its working fine.
Thanks for your response. I will ping I will face any issue in deployment. Closing this for now.

@staltz I make it to work with above solution.
I did add .xcode.env.local in ios folder in vs code (not in xcode) and with command react-native run-ios its working fine.
But when I am trying to run it from Xcode getting the same error Command PhaseScriptExecution failed with a nonzero exit code, I think Xcode is having another node version. Anything which I am doing wrong because of that xcode is not recognizing my .xcode.env.local file.

Good that you discovered the underlying problem.

Xcode just sometimes misbehaves. I wish I had a better answer, but given that it's such an opaque tool (not open source), we can't dig deeper. I would recommend restarting your computer, cleaning all possible caches, deleting the project's "build" folder that is usually in Application Support folder, and then trying again.
