原因
ブランチ名が変更されており、update時にgithubで見つからなかったことが原因。
解決方法
ブランチ名が変わっている箇所を削除して、git cloneすることで解決。
流れ
下記のようにエラーになる、メッセージを読んでみるとブランチの名前が変わったか消されて見つけられないとのこと。brew tap –repairを実行してみるもエラー。
[xxxxx@xxxxxx] ~
% brew update
fatal: couldn't find remote ref refs/heads/master
Error: Fetching /usr/local/Homebrew/Library/Taps/rcmdnk/homebrew-file failed!
Error: Some taps failed to update!
The following taps can not read their remote branches:
rcmdnk/file
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`
[xxxxx@xxxxxx] ~
% brew tap --repair
fatal: couldn't find remote ref refs/heads/master
Error: Failure while executing; `git -C /usr/local/Homebrew/Library/Taps/rcmdnk/homebrew-file fetch origin` exited with 128.githubを確認すると確かに、ブランチがmainに変わってる。
