While making test app on Rhosync 2.0, i was facing this Redis error on my windows.
For rhosync 2.1 you need redis-1.2.6, in case of windows. If you have already installed redis gem, automatically redis-2.xx will be installed on the system.
When you run rake redis : start
Following error will pop :
No need to uninstall or re-install redis.
Simply download following .zip files and extract the same in your c drive.
$ rake redis:start
It will Work.
