我该怎么做才能解决这个问题并成功安装 devtools？
➜ ~ brew install devtools
Updating Homebrew...
Error: No available formula with the name "devtools"
==> Searching for a previously deleted formula (in the last month)...
Warning: homebrew/core is shallow clone. To get complete history run:
git -C "$(brew --repo homebrew/core)" fetch --unshallow
Error: No previously deleted formula found.
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
==> Searching taps on GitHub...

➜ ~ git -C "$(brew --repo homebrew/core)" fetch --unshallow
