Error: could not find cache store adapter for redis_cache_store
What's Causing This Error
The error 'could not find cache store adapter for redis_cache_store' pops up when Rails is unable to locate the Redis cache store adapter that should have been loaded. The problem can be caused by various factors, including:
-
Missing dependencies: If the Redis gem is not installed or not included in the Gemfile, Rails will not recognize Redis as a cache store adapter.
-
Wrong configuration: If the Redis configuration is incorrect, such as the host or port number being wrong, Rails cannot connect to Redis and therefore won't recognize it as a cache store adapter.
-
Compatibility issues: Different versions of Redis and the Redis gem may not be compatible, causing the adapter to fail to load.
Solution - Here's How To Resolve It
To fix the 'could not find cache store adapter for redis_cache_store' error, try these solutions:
-
Install the Redis gem: Make sure the Redis gem is installed and included in your Gemfile by adding
gem 'redis'
to your Gemfile and runningbundle install
. -
Check Redis configuration: Ensure that the Redis configuration in your
config/application.rb
orconfig/environments/*.rb
files is correct, including the host and port number. You can also check if Redis is running and accessible using the Redis CLI. -
Check Redis and Redis gem compatibility: Check the Redis gem documentation to ensure that the version of Redis you're using is compatible with the version of the Redis gem you've installed. You can also try upgrading the Redis gem to the latest version, or downgrading it to a known working version.
