homebrewのアップデートは「brew update」でアップデートしていたましたが、以下のエラーでアップデートできませんでした。
アップデートのエラーメッセージ
$ brew update
Error:
homebrew-core is a shallow clone.
homebrew-cask is a shallow clone.
To brew update, first run:
git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow
git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask fetch --unshallow
This restriction has been made on GitHub's request because updating shallow
clones is an extremely expensive operation due to the tree layout and traffic of
Homebrew/homebrew-core and Homebrew/homebrew-cask. We don't do this for you
automatically to avoid repeatedly performing an expensive unshallow operation in
CI systems (which should instead be fixed to not use shallow clones). Sorry for
the inconvenience!homebrewのバージョンを確認
$ brew --version
Homebrew 2.7.0
