Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!
Warning: A newer Command Line Tools release is available.
Update them from Software Update in System Preferences or run:
softwareupdate --all --install --force
If that doesn't show you an update run:
sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install
Alternatively, manually download them from:

は取り返しつかなそうなので、こっちを試してみる
sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install
メッセージが以下だけになったので指示に従ってbrew cleanup
を実行してみる
