When I start redis on OSX, it exits because it says it can't handle RDB format version 7. Here's the output:
Server started, Redis version 3.0.7
Can't handle RDB format version 7
Fatal error loading the DB: Invalid argument. Exiting.
The redis gem version in the gemfile was 3.2.2, but I changed it to 3.0.7 to see if that would make it work. It didn't.
How do I fix this? I don't have anything important in there so I'm fine with resetting it to another version or uninstall and reinstall redis.
