[Vuejs]-Vue-native-script / environment not working

Do the pod install manually to check where is the problem:

1. Remove your current build: tns platform remove ios
2. Build the app source code only: tns build ios --bundle
3. Navigate to the project folder platforms/ios, run pod install to see if there is error. If it’s still same error, remove Podfile.lock if any, then try pod repo update
