Typings firebase and problems after the new rc1

Hello! after updating the new ionic rc1 I found the following error. Problems with typings

I seem to have duplicated some of typings or firebase or any configuration that gives me this error. Can anybody help me?

Edit the files specified and find those duplicate identifiers, then get rid of one of them.

I had similar errors in localforage. I’ve solved it by removing an old typings directory (maybe also also a typings.json, if present) which is not needed anymore. My advice would be to try that before tampering directly in a module.
