Error: Unknown command: cask

[mavabene]

I'm new to programming. I can code some in python and Matlab but I don't understand command line interfaces or what is going on behind the scenes.

I was doing a tutorial to learn about Mac Terminal and they had me install homebrew. Then Cask. I tried to run "brew cask help" and I get "Error: Unknown command : cask". I have googled and tried things and added paths and brew doctored and upgraded and reinstalled and cleared directories and cleaned up and I consistently just get this error. What is going on??

Any help would be greatly appreciated! And help with basic explanations even more so! Thank you.

Your tutorial is outdated. cask is no longer a brew command. When you want to install a Cask, you just do brew install or brew install --cask instead of brew cask install.

Aside: It took me a bit to realize that anywhere the docs said to run brew <something> I actually needed to run ./bin/brew <something>

No, the docs definitely intend for you to run brew <something>. There's something off about your config if you need to run ./bin/brew <something> instead.

Dunno what to say. brew points to the one in my normal PATH, even when in the repo folder.

This is intentional – modifications to Homebrew code (for a potential PR) are made in your existing Homebrew installation/source tree, in a new branch. So you needn't separately clone the Homebrew repository at all. See https://docs.brew.sh/How-To-Open-a-Homebrew-Pull-Request#core-brew-code-related-pull-request (specifically, cd "$(brew --repository)"). Once you've made the changes you want to, running brew <something> should work just fine.

Aah, guess I just missed that. Thanks!

So this is outdated too?

Yeah, anything that mentions brew cask is outdated.

[carlocab]

The brew cask install part is outdated. Generally, any command that is written as

brew cask <command>

can/should be run as

brew <command> --cask
