FBReactNativeSpec, PhaseScriptExecution failed with a nonzero exit code

Question

I have been having issues trying to create an IOS build of a react native application. Originally I made this on windows with an android emulator. Then I tried to build the react native code on mac with xcode but I can't get past this error.

I have tried a couple things like reinstalling node and unsetting the PREFIX variable in the find-node script but I have not gotten any further

When inspecting the error it says:

• FBReactNativeSpec - Uncategorized - PhaseScriptExecution failed with a nonzero exit code

int he details there is another error that says:

• bash: mobile/node_modules/react-native/scripts/../Libraries: No such file or directory

Answer 1

I had the same issue on my MacBook Pro with M1 chip. I managed to get rid of the FBReactNativeSpec error by editing the Project settings.

Try the following:

1. In Xcode select your app's project and then select the target.

2. In Terminal enter the following command to find out the path of your node installation:

which node

This should give you a path. Something like:

/Users/thomashuber/.nvm/versions/node/v16.14.0/bin/node

3. Copy this path.

4. In Xcode with the target selected click on Build Phases and open Bundle React Native code and images

5. Replace NODE_BINARY=node. Instead of node enter the path that you have copied so that it is something like this NODE_BINARY=/Users/thomashuber/.nvm/versions/node/v16.14.0/bin/node
