Homebrew cask option not recognized?

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.

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

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. – Coquille 8/2, 2021 at 17:26

Found link in homebrew's Github discussion with explanation of behavior change: github.com/Homebrew/discussions/discussions/… – Undies 19/2, 2021 at 18:44

"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 – Whitewing 25/2, 2021 at 21:3

cask was warned that would be obsolete and removed in future brew versions, and should be replaced by --cask – Exudate 18/4, 2021 at 18:10

nice brew install --cask font-fira-code – Lin 29/9, 2021 at 10:24

@Ederson-Badeca I still needed cask to install docker for desktop. brew install --cask docker – Endoenzyme 13/12, 2021 at 0:25

brew install cask your-package worked for me instead – Fossick 23/12, 2021 at 8:23

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'. – Altricial 19/1, 2022 at 14:13

As of 2021 use this command instead:

brew install --cask your-package

Deepsea answered 7/9, 2021 at 6:4 Comment(3)

This is not correct, this will install the packages cask and your-package. See https://mcmap.net/q/44930/-homebrew-cask-option-not-recognized for the correct answer. – Bhang 4/1, 2022 at 20:53

it's correct for me too on MacOS M1 2021 – Aaren 28/2, 2022 at 5:22

wow, this answer is extremely wrong. Can this please be deleted or something? – Sciatic 3/9, 2022 at 22:55

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

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. – Oxytetracycline 9/2, 2021 at 3:14

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" – Initiatory 10/2, 2021 at 16:26

the homebrew/cask is worked on me, but it still get error after I ran cask – Sprinkling 11/5, 2021 at 5:8

I had the same issue. Now you should use:

brew install --cask <package>

instead of:

brew cask install <package>

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

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

Use brew install --cask <package_name>

It worked for me after trying multiple permutations and combinations.

None of these answers—despite some of them being correct at the moment—are showing their work and so may become no longer correct if this changes again.

I ran into this issue, stumbled on this page, and it was enough to get me curious about the change in command line and where that might be documented. Turns out you can go right here:

https://formulae.brew.sh/cask/

and any of those you click on will show you the current command to use. So, for instance, the iterm2 page:

https://formulae.brew.sh/cask/iterm2

right at the top it's got the correct command to use so if they ever change it, you'll see what the new syntax is.

Marjie answered 25/3, 2021 at 0:15 Comment(1)

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. – Valse 14/4, 2021 at 12:58

brew tap caskroom/cask

brew install brew-cask

Now, you are ready to brew cask.

Hamer answered 29/8, 2016 at 14:35 Comment(2)

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. – Anabaptist 31/8, 2016 at 7:15

@JeremyJohn answer is out to date, for installing Android sdk you should use this command:

brew install --cask android-sdk

I don't why the highest voted answer doesn't work for me. But you can do something like brew install homebrew/cask/appName

Since Homebrew 2.6.0 released in 2020.12.01, brew cask has been deprecated and later dropped.

Homebrew not only manages TUI packages (formulae from the homebrew-core repo), it's also capable of managing GUI packages (casks from homebrew-cask repo). In the old days, brew commands like brew list, brew outdated take effect only on formula. Cask operations are separated into brew cask.

Homebrew has prioritized support for casks since 2.6.0. All the brew commands take effect on both formulae and casks. You must specify --formula or --cask explicitly to indicate them separately.

# Some examples
brew list # both formula and cask
brew list --formula
brew list --cask

brew outdated # both formula and cask
brew outdated --formula
brew outdated --cask

For me,

brew install <program_name> has worked fine till now.

For example, I was trying to install Oracle Virtual Box and the formula for it was listed as

$ brew cask install virtualbox.

But, $ brew install virtualbox worked just fine. I found that it was installing the application as cask as shown in the screenshot.

I think homebrew automatically takes care of the cask dependency.

Why do I get this error: fatal: ambiguous argument 'refs/remotes/origin/master': unknown revision or path not in the working tree. – Fauna 29/3, 2021 at 18:1

I would recommend following the below steps.

Step 1: Run brew install --help

Might show something like this.

Usage: brew install [options] formula|cask [...]

Install a formula or cask. Additional options specific to a formula may be
appended to the command.

Step 2: follow the hint ot help create the command and execute.

brew install cask chromedriver

Instead of this

brew cask install yourprogram

I have run:

brew install --cask yourprogram

One other thing to check is that it may be installed but not linked:

$ brew install caskroom/cask/brew-cask
Warning: caskroom/cask/brew-cask-0.59.0 already installed, it's just not linked

This is easily fixed by running:

$ brew link brew-cask

I had the same issue before. Had my head scratching and finally figured out and use the commands like:

brew commands --cask

This worked for me.

brew cask is no longer a brew command. Use brew <command> --cask instead.

Example Syntax:-

Use:

brew install --cask <package_name>

Instead of:

brew cask install <package_name>
