Cannot find module after update ionic CLI

Hello, I updated the ionic CLI to the latest version, but now the ionic serve on my old project with beta11 doesn’t work anymore… I got the following errors:

TypeScript error: C:/Users/victo/Documents/DEV/ionic/outclassapp/node_modules/ionic-angular/util/mock-providers.d.ts(3,78): 
Error TS2307: Cannot find module '../../src'.
TypeScript error: C:/Users/victo/Documents/DEV/ionic/outclassapp/node_modules/ionic-angular/util/mock-providers.d.ts(4,35): Error TS2307: 
Cannot find module '../../src/components/nav/nav-controller-base'.

Someone knows what I need to do to run my beta11 project now?
