cannot load such file -- redis/connection/hiredis

Hello!

I'm trying to set this up for the first time on my machine, and getting trouble in any app I try and use the gem. Easily repro'd (for me) with the demo instructions (section 7) here: https://github.com/kigster/simple-feed#7-running-the-examples-and-specs

Following those steps, I get:

LoadError:
  cannot load such file -- redis/connection/hiredis
# ./lib/simplefeed/providers/redis/driver.rb:4:in `<top (required)>'

I get the same error with this in my Gemfile:

gem "hiredis", "~> 0.6.0"
gem "redis", ">= 3.2.0", require: %w[redis redis/connection/hiredis]

When starting my server:

22:07:01 css.1  | rails aborted!
22:07:01 css.1  | LoadError: cannot load such file -- redis/connection/hiredis
22:07:01 css.1  | <internal:/Users/peterehrlich/.rbenv/versions/3.2.2/lib/ruby/3.2.0/rubygems/core_ext/kernel_require.rb>:37:in `require'

Have tried a few steps to no effect - such as installing hiredis via homebrew (although I saw in another thread that that's not necessary as the rubygem is self contained). Any tips for troubleshooting this? Thanks!
