Wrong number of arguments for Homebrew on xcode12

Hi

Invoking Homebrew from travis.yml in xcode12 machine leads to following error:

Updating Homebrew
$ rvm $brew_ruby do brew update 1>/dev/null
Installing Homebrew Packages
$ rvm $brew_ruby do brew bundle --verbose --global
Error: wrong number of arguments (given 2, expected 1)
Please report this bug:
https://github.com/Homebrew/homebrew-bundle/issues

My travis.yml:

addons:
  homebrew:
    packages:
    - ninja
    update: true

Build link: https://travis-ci.com/github/MIPT-ILab/mipt-mips/jobs/365645568

Hmmm. I can’t reproduce it.

https://staging.travis-ci.org/github/BanzaiMan/travis_staging_test/builds/762177

I can’t reproduce it now as well… let’s see if the problem appears again later.

Please reopen this if you see it again.
