React Native - FBReactNativeSpec Command PhaseScriptExecution failed with a nonzero exit code

For me anyone of this solutions work because, with Xcode 14.2 and RN0.70.5, there is the following 2 files in ios folder which fixe node version with the path (I don't know since which version and which one adds this files) :

1. .xcode.env
2. .xcode.env.local

If you are this files inside ios folder just do this (with or without nvm) :

which node

And put the patch inside the .xcode.env.local like this :

export NODE_BINARY="/Users/Blabla/.nvm/versions/node/v16.14.0/bin/node"

If this files doesn't exist, try to add it and maybe Xcode will take it into account :

Inside ios/.xcode.env

# This `.xcode.env` file is versioned and is used to source the environment
# used when running script phases inside Xcode.
# To customize your local environment, you can create an `.xcode.env.local`
# file that is not versioned.

# NODE_BINARY variable contains the PATH to the node executable.
#
# Customize the NODE_BINARY variable here.
# For example, to use nvm with brew, add the following line
# . "$(brew --prefix nvm)/nvm.sh" --no-use
export NODE_BINARY=$(command -v node)

Inside ios/.xcode.env.local

export NODE_BINARY="/Users/Blabla/.nvm/versions/node/v16.14.0/bin/node"

If you shut down your computer or did a recent upgrade to node or nvm something in the cache folder gets reset and the build fails. The code in the react native node_modules/react-native/scripts/find-node.sh script related to nvm. Following this advice: https://stackoverflow.com/a/70104375/5927929 worked for me with a small change.

My specs: Mac intel chip RN 0.68.2 nvm (0.33.11) && node (v18.3.0) install

Steps:

1. nvm unalias default
2. nvm alias default node
3. Build in xcode...done

Took me ages to figure this out, my problem was unrelated to any of the other answers.

The issue was that my project's full path contained an empty space, so turning

/Users/radu/Projects/midi control/ua/UaRemoteControl

into

/Users/radu/Projects/midi-control/ua/UaRemoteControl

fixed the build error in XCode.

For me, the issue was due to space in folder name.

I had the problem when the name of the parent folder was 'Personal Development'. I have changed it to 'PersonalDevelopment' and the problem has vanished.

In my case this error raising due to node path is not set in PATH Variables. Try to run below command it will set missing node path in PATH variable and it resolve the error.

sudo ln -s $(which node) /usr/local/bin/node

https://reactnative.dev/docs/new-architecture-troubleshooting#:~:text=Command%20PhaseScriptExecution%20failed%20with%20a,libraries%20(FBReactNativeSpec%2C%20rncore).

Fixed this by updating node_modules/react-native/scripts/find-node.sh at line # 7.

set -e
 
to

set +e

In my case:

• M1 chip
• MacOS Ventura 13.3.1
• Xcode Version 13.4
• node v14.18.1

I had node & npm installed in 2 places - 1 with brew and another with nvm.

You can check by using these commands

/usr/local/bin/node -v
node -v

If the above 2 give 2 different versions, Your issue also could be the same.

I removed the ones in the /usr/local/bin

rm -rf /usr/local/bin/node
rm -rf /usr/local/bin/npm

Installed v14.18.1 again in nvm

nvm use v20.1.0
nvm uninstall node 14.18.1
nvm install node 14.18.1
nvm use v14.18.1

Removed all unused versions from nvm

nvm uninstall node 20.1.0

Then symlinked node from nvm to bin

ln -s $(which node) /usr/local/bin/node

then cleaned the DerivedData folder

rm -rf ~/Library/Developer/Xcode/DerivedData/* && rm -rf ~/Library/Caches/org.swift.swiftpm

Then cleaned builds from Xcode and built again

Simply delete the FBReactNativeSpec file from the Pods as shown in the image below.enter image description here

Ok, worth trying this.

2 different solutions :

1: As soon as we get this error message:

Always scroll up & read the issue if written in that log file. Any issues like syntax error or issue related to your js code (like multiple imports in your js files or if you had forgot to import something). If yes, you can fix that first & re build it.

In my case I had multiple imports of one of the RN components.

if not

2: got to 'Keychain access' in your mac, lock & unlock login and re build it, this may help you.

And make sure to 'cd ios' && 'pod install' if you have forgot to do it after installing any of the npm package.

In my case, with Node.js version 16.20.2 installed on my macOS Sonoma 14.1 using the DMG file, when I attempted to execute nvm alias default node, I encountered the following error message:

! WARNING: Version 'node' does not exist.

To resolve this issue, I followed these steps:

1. Reinstalled Node.js version 16.20.2 using the following command:

nvm install 16.20.2

2. Subsequently, I set the "default" alias using the complete version number, rather than "node," with the following command:

nvm alias default 16.20.2

It's worth noting that I'm using Xcode 15.0.1.

The issue for me was the newest Apple Developer Program License Agreement was not accepted by the owner of my Apple account. So it wasn't creating any ad hoc provisioning profiles until my boss accepted it.

tl;dr - sign in to developer.apple.com and make sure to accept the agreement.

In node_modules/react-native/scripts/find-node.sh, do

change line no 7 set -e. ==> set +e

In case someone else tried everything mentioned here and in other threads, and it didn't work, here is what worked for me!

• I uninstalled my nvm install
• installed node globally (https://nodejs.org/en/download/)
• ran pod install and got this error message:

[!] CocoaPods could not find compatible versions for pod "hermes-engine": In snapshot (Podfile.lock): hermes-engine (from ../node_modules/react-native/sdks/hermes/hermes-engine.podspec) In Podfile: hermes-engine (from ../node_modules/react-native/sdks/hermes/hermes-engine.podspec) It seems like you've changed the version of the dependency hermes-engine and it differs from the version stored in Pods/Local Podspecs. You should run pod update hermes-engine --no-repo-update to apply changes made locally.

But instead of running the command they gave me, I deleted Podfile.lock and the Pods directory, then reran pod install, and the build finally worked!

1. Determine where your node binary is:

    $ which node
    /opt/homebrew/bin/node

2. Add a fixer function in your Podfile:

    def fix_fb_react_native_spec(installer)
      installer.pods_project.targets.each do |target|
        if target.name == 'FBReactNativeSpec'
          target.build_configurations.each do |config|
            if config.name == 'Debug' or config.name == 'Release'
              config.build_settings['NODE_BINARY'] = '/opt/homebrew/bin/node'
            end
          end
        end
      end
    end

3. In your postinstall, add fix_fb_react_native_spec(installer) like so:

     post_install do |installer|
        react_native_post_install(installer)
        fix_fb_react_native_spec(installer)
      end

4. Pod install

5. Rebuild (ideally with a clean build)
