ひさびさにbrew使ったら更新でちょっとハマった話
ひさびさにbrewで検索を実行したら↓なエラーが
% brew search hoge
Warning: Error searching on GitHub: GitHub API Error: Requires authentication
The GitHub credentials in the macOS keychain may be invalid.
Clear them with:
printf "protocol=https\nhost=github.com\n" | git credential-osxkeychain erase
Create a GitHub personal access token:
https://github.com/settings/tokens/new?scopes=gist,repo,workflow&description=Homebrew
echo 'export HOMEBREW_GITHUB_API_TOKEN=your_token_here' >> ~/.zshrc
Github Token設定してもいいんだけど...と思って検索してみたら
こんな記事が（安定のDevelopers IO→いつもお世話になっております）
更新すれば良さそうなので
% brew update
が、エラーが出てたので
Homebrew自体の問題を確認
% brew doctor
Warning: You have an unnecessary local Cask tap.
This can cause problems installing up-to-date casks.
Please remove it by running:
brew untap homebrew/cask
Warning: You have an unnecessary local Core tap!
This can cause problems installing up-to-date formulae.
Please remove it by running:
brew untap homebrew/core
メッセージ通りに実行
% brew untap homebrew/cask
% brew untap homebrew/core
もう一回
% brew update
fatal: couldn't find remote ref refs/heads/master
Error: Fetching /opt/homebrew/Library/Taps/dart-lang/homebrew-dart failed!
Error: Some taps failed to update!
The following taps can not read their remote branches:
dart-lang/dart
This is happening because the remote branch was renamed or deleted.
Reset taps to point to the correct remote branches by running `brew tap --repair`
使ってるパッケージのブランチが変更になってる模様
% brew tap --repair
：
==> dart-lang/dart: changed default branch name from master to main!
向き先もなおせたので再度
% brew update
エラー出なくなったのでパッケージも更新
% brew upgrade
なおた
あと不要なfomula削除（やらなくても良い）
ちなみに--dry-runオプションも使える
% brew autoremove
