brew cask doctor error "Error: wrong number of arguments (1 for 0)"

[psyrendust]

When running brew cask doctor I get the following output:

 larrygordon in /usr
○ → brew cask doctor
Error: wrong number of arguments (1 for 0)

  Most likely, this means you have an outdated version of homebrew-cask. Please run:

      brew update && brew upgrade brew-cask && brew cleanup && brew cask cleanup

  If this doesn’t fix the problem, please report this bug:

Can’t reproduce. Can anyone of @caskroom/maintainers?

[claui]

@psyrendust Could you please do echo $HOMEBREW_CASK_OPTS and post the result here?

[psyrendust]

It also doesn't list any of the casks that I installed either:

 larrygordon in ~
○ → brew cask list --verbose
Error: No available Cask for --widgetdir=~/Library/Widgets

 larrygordon in ~
○ → ls /usr/homebrew-cask/Caskroom
animated-gif-quicklook  cert-quicklook  qlcolorcode  qlmarkdown     qlstephen  quicklook-csv   quicknfo            webpquicklook
betterzipql             provisionql     qlimagesize  qlprettypatch  qlvideo    quicklook-json  suspicious-package

Which is really odd. I uninstalled brew-cask and reinstalled it after a restart of my machine. I'm still seeing the same results.

[vitorgalvao]

Try removing options from HOMEBREW_CASK_OPTS. Not only are most of those redundant, at least one of them doesn’t exist anymore (--widgetdir, as widget support as been removed a while ago) and is likely the issue, as per you last post.

[claui]

I suspect the issue might be caused by your HOMEBREW_CASK_OPTS environment variable containing the

--widgetdir

option, which homebrew-cask no longer supports. Support for widgets has been removed altogether earlier this year as per #8751.

To fix this, locate the file where your HOMEBREW_CASK_OPTS is being declared. (If unsure, do grep -R HOMEBREW_CASK_OPTS ~/.*). Edit that file and remove the part from your HOMEBREW_CASK_OPTS variable where it says --widgetdir=~/Library/Widgets. Close Terminal.app and try again.

Does that fix both issues?

[claui]

@vitorgalvao High five 😂

[vitorgalvao]

So close. I still saw your comment appear mere seconds after. Nice thinking with the HOMEBREW_CASK_OPTS.

[psyrendust]

Success! Removing --widgetdir option did it.
