Problem running newly ejected expo app

Hi I am seeing an issue when trying to build an IPA in xcode from a freshly created expo app which is then ejected

Steps to reproduce

  1. expo init (expo-template-blank)
  2. yarn eject
  3. open ./ios/projectname.xcodeproj in xcode
  4. Add developer profile and targets in xcode
  5. Product -> Archive in xcode

I get the following error

For anyone playing at home, it was due to me using nvm and my default nvm version being set to v6
