For context, I have the same installation problem but i'm trying to install on a brand new macbook pro , Apple M3 Max, 36GB, Sonoma 14.3.1.

Had the same problem today on mac, fixed by changing 3 (i think) instances of File.exists? to File.exist? and 1 instance of Dir.exists? to Dir.exist? in /usr/local/Homebrew/Library/Taps/redis-stack/homebrew-redis-stack/Casks/redis-stack-server.rb

I have the same issue

just ran into this and @mattweston suggestion fixed for me as well. just find where you installed redis-stack-server.rb and change .exists to .exist in the four places.

mine was located /opt/homebrew/Library/Taps/redis-stack/homebrew-redis-stack/Casks/redis-stack-server.rb

This fix worked for me as well, thanks @mattweston!

Just to add some clarity, the file you want to edit depends on whether you have an Intel or Apple Silicon (M series) Mac.

For Intel Macs, the file is: /usr/local/Homebrew/Library/Taps/redis-stack/homebrew-redis-stack/Casks/redis-stack-server.rb

For Apple Silicon Macs, the file is: /opt/homebrew/Library/Taps/redis-stack/homebrew-redis-stack/Casks/redis-stack-server.rb

Just replace all instances of .exists? with .exist? in that file. There should be four of them.

Apple M1, had to fix the exists into exist in the following file: open /opt/homebrew/Caskroom/redis-stack-server/.metadata/7.2.0-v10/20240404171843.440/Casks/redis-stack-server.rb

[Extend-Apps]

redis-stack-server.rb

This worked for me as well

Apple M1, had to fix the exists into exist in the following file: open /opt/homebrew/Caskroom/redis-stack-server/.metadata/7.2.0-v10/20240404171843.440/Casks/redis-stack-server.rb

Apple M1 Pro, had to do this and was able to get this part of things working
