Issues with homebrew tap and cask-CodePudding

I am trying to set up my own Homebrew tap for casks which aren't available on the official Hombrew tap. I am getting a Error: Cannot tap depal1/gamezz: invalid syntax in tap! and "invalid formula" errors on my casks when I try to install them through either brew install or brew install --cask.

I have checked the Homebrew documentation, and I haven't found these errors.

The homebrew tap is hosted at https://github.com/Depal1/homebrew-gamezz

CodePudding user response：

There is no error in the cask itself but according to the documentation you have to:

Place any cask files you wish to make available in a Casks directory at the top level of your tap.

Such as in https://github.com/Homebrew/homebrew-cask
