Homebrew-cask: [brew cask upgrade] Error: undefined method `<=' for nil:NilClass

Created on 2 Mar 2018  路  7Comments  路  Source: Homebrew/homebrew-cask

General troubleshooting steps

  • [x] I have retried my command with --force and the issue is still present.
  • [x] I have checked the instructions for reporting bugs (or making requests) before opening the issue.

    • [x] None of the templates was appropriate for my issue, or I鈥檓 not sure.

  • [x] I ran brew update-reset && brew update and retried my command.
  • [x] I ran brew doctor, fixed as many issues as possible and retried my command.
  • [x] I understand that if I ignore these instructions, my issue may be closed without review.

Description of issue

Seems like there's a missing Nil check, or something to that effect.

Try brew cask reinstall --force anki. If that doesn鈥檛 work, delete $(brew --prefix)/Caskroom/anki and try again.

I don't really mind that it doesn't work on old outdated casks, but it would be nice if it didn't explode like that. Rather it should give back some sort of feedback to the user.

You will need to do https://github.com/caskroom/homebrew-cask/issues/44504#issuecomment-370029715 for each Cask that errors.

commitay picture commitay on 12 Mar 2018

To be clear, I reported this not just to get the problem fixed. But rather to make sure cask gives the next fellow a better error message then raising an error like this.

Is this issue resolved? I am facing a similar issue on the filezilla installation using cask. However, after trying the instructions above the issue still presents. Any ideas ? Thank you .
