ShopifyのTheme Kit導入に際してターミナルで以下のコマンドを入力したところHomebrewでError: homebrew-core is a shallow clone で怒られた時に解決した方法を残しておきます。
解決方法
解決策はエラー文で表示されたコマンドを実行
git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow
エラー内容
~ % brew tap shopify/shopify
Error:
homebrew-core is a shallow clone.
To `brew update`, first run:
git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow
This command may take a few minutes to run due to the large size of the repository.
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!
Deeplで翻訳したところ以下のような内容
更新を行うには、まず実行します。
git - C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow
このコマンドはリポジトリのサイズが大きいため、実行に数分かかることがあります。
この制限は、GitHub の要請により行われました。
クローンは、木の配置や交通量が多いため、非常に高価な作業となります。
とのこと。
つまり
shallow clonesは非常に重たい処理をおこなってしまうためGitHubの要請を受けて高負荷のshallowの繰り返しを避けるために自動的に浅いクローンを使用しないように修正されています。
ふむ
ということで
