I try to run my app with --prod, but I throw this error, TypeError: Cannot read property 'codeGen' of undefined

Ionic Framework ionic-v3
8

I solved this problem migrating my app to Ionic 3.0.1, this problem happens by a mismatch between ionic version and angular version, Angular version must be superior to version 2.3.x to work ok, you can take two paths:

  1. update everything to Ionic 3.0.1(Guide: How to update to Ionic 3.X )
  2. update angular version but be careful to use compatible versions.(https://github.com/driftyco/ionic/blob/master/CHANGELOG.md)
