Homebrew cask option not recognized?

Question

I am following an online resource for installing two Mac utilities

http://www.economyofeffort.com/2014/08/11/beyond-ctrl-remap-make-that-caps-lock-key-useful/

Here is the pertinent section:

Install both Karabiner and Seil. (Here again, if you use Homebrew Cask, you can do this with

$ brew cask install karabiner and

$ brew cask install seil

But the cask option is not recognized?

06:51:35/shared $brew cask install seil
Error: Unknown command: cask

Then, just for laughs I tried the command without the cask:

06:55:01/shared $brew install seil
Error: No available formula for seil
Searching formulae...
Searching taps...
Caskroom/cask/seil

It is not clear what the last line of output even means: nothing seems to have happened on the system.

I am on Yosemite.

Solution 1

As of 2021, the answer to this question for me was that instead of

brew cask install myprogram

I should run:

brew install --cask myprogram

Solution 2

As of 2021 use this command instead:

brew install cask your-package

Solution 3

UPD: since the command brew install caskroom/cask/brew-cask gives you the following error Error: caskroom/cask was moved. Tap homebrew/cask instead. please run brew install homebrew/cask

To use brew cask you should have it installed, this is a extension of brew, is not native.

To install it you need to run brew install caskroom/cask/brew-cask from your command line

Homebrew Cask Github

Solution 4

I had the same issue. Now you should use:

brew install --cask <package>

instead of:

brew cask install <package>

Solution 5

You can also just brew install Caskroom/cask/seil. It will automatically tap the correct cask for you :)

brew didn't find the brew-cask formula, but did find brew install homebrew/completions/brew-cask-completion instead. That enabled brew cask for me.

I was trying to use it but I think you don't need to pass cask anymore. I just hit: brew install spotify It worked for me.

caskroom/cask was moved, i need to use homebrew/cask instead. brew install caskroom/cask/brew-cask Error: caskroom/cask was moved. Tap homebrew/cask instead.

I had the same issue @KDFinal I finally got it to work by changing the way I reference the file I was wanting to install to: "brew install --cask homebrew/cask-versions/adoptopenjdk8"

"All brew cask commands have been deprecated in favour of brew commands (with --cask) when necessary" read on brew.sh/2020/12/01/homebrew-2.6.0

Error: caskroom/cask was moved. Tap homebrew/cask instead.

Why do I get this error: fatal: ambiguous argument 'refs/remotes/origin/master': unknown revision or path not in the working tree.

[Sacha Guyer]

Thanks for this answer. You are right with your examples. Also, if you go to brew.sh, in the cask section, it lists the "new" command $ brew install --cask firefox, while earlier, the format of the command was e.g. brew cask install skype. Apparently this was changed in 2.6.0. The blog/release notes brew.sh/2020/12/01/homebrew-2.6.0 mention: "All brew cask commands have been deprecated in favour of brew commands (with --cask) when necessary", I did not find further details why they made this change though.

cask was warned that would be obsolete and removed in future brew versions, and should be replaced by --cask

[Berlian]

the homebrew/cask is worked on me, but it still get error after I ran cask

[Stephen Ó Connor]

duplicate of answer from @DolDurma

[Karan]

[Codeversed]

Finally, Thank you!

@Ederson-Badeca I still needed cask to install docker for desktop. brew install --cask docker

No available formula or cask with the name "caskroom/cask/seil". ==> Searching for similarly named formulae... Error: No similarly named formulae found.

[Steve Tauber]

This particular package has been obsoleted github.com/tekezo/Seil

[Valiant]

brew install cask your-package worked for me instead

[Daniel Compton]

This is not correct, this will install the packages cask and your-package. See stackoverflow.com/a/66081492/826486 for the correct answer.

[Nick the Community Scientist]

Unless there are conflicting cask and formulae names (check handbrake as an example using brew search handbrake) then the standard format of brew install nameOfYourProgram should work. Alternatively, you should be using the --cask flag according to brew install -h which reports '--cask' and not 'cask'.

[Nick the Community Scientist]

As I commented in the answer by @Jeremy John above, this is correct.

[Rom's]

it's correct for me too on MacOS M1 2021
