Description

When i build ios release scheme locally i get no errors, but when i build on travis the release scheme i get this error under Running script 'Bundle React Native code and images':

File /Users/travis/Library/Developer/Xcode/DerivedData/TestApp-bktrthrvpvtbhdcrrzrzfekixdcy/Build/Products/Release-iphonesimulator/TestApp.app/main.jsbundle does not exist. This must be a bug with

I checked that when i run it locally the main.jsbundle is copied inside this folder but on travis this file is not copied although before building i run: react-native bundle --platform ios --dev false --entry-file index.js --bundle-output ios/main.jsbundle

I am using react-native v0.56

Reproducible Demo

This is my .travis.yml configuration:

- language: objective-c
      sudo: required
      xcode_project: ios/TestApp.xcworkspace
      xcode_scheme: ios/Release
      node_js: false
      env:
        - TEST='IOS RELEASE BUILD'
      before_install:
        - nvm install 9.10.0
      install:
        - brew install yarn
        - yarn install
        - npm install -g react-native-cli
      script:
        - react-native bundle --platform ios --dev false --entry-file index.js --bundle-output ios/main.jsbundle
        - cd ios
        - xcodebuild -workspace TestApp.xcworkspace -scheme Release -sdk iphonesimulator ONLY_ACTIVE_ARCH=NO | xcpretty -c; exit ${PIPESTATUS[0]}

You can have a look inside the Xcode project build phases. There should be a build phase script called Bundle React Native code and images with something like

export NODE_BINARY=node
../node_modules/react-native/scripts/react-native-xcode.sh

in it. This is the script that's supposed to run on build and bundle the js for you.

Could it be something to do with the path or the node binary path on your Travis CI system?
I notice your travis.yml file says node_js: false, but I don't know enough about Travis to know what this means.

@samjt Thank you for the reply.
My Bundle React Native code and images is configured like this:

Do you think this problem could be related to the certificates for IOS? As i haven't configured them.

Finally, after searching i solved it by adding this line to my travis.yml

nvm alias default v9.10.0

after nvm install 9.10.0

Apparently, the script was using an other version of node and by setting this i forced it to use this node version
