brew コマンドでインストールしようとしたところエラーが発生しました。

どうにかして使えるようにした時の記録です。

発生したエラー

tmux を利用しようと思い、インストールしてみたところ下記のエラーが発生しました。

$ brew install tmux

brew が古くなったのかと思い、brew の update を試みました。

$ brew update

解決するためにやったこと

困り果てていたところ、同じ問題に遭遇している人が解決策を書いていくれていました。

/usr/local のパーミッション の修正

$ ls -la /usr/local
total 96
drwxr-xr-x  23 root      wheel    782 11  4  2017 .

$ sudo chown $(whoami):admin /usr/local
$ ls -la /usr/local
total 96
drwxr-xr-x  23 hogehoge  admin    782 11  4  2017 .

Homebrew を更新

$ cd /usr/local/Library/Homebrew

$ git pull -q origin refs/heads/master:refs/remotes/origin/master

これで brew update が使えるようになりました。

$ brew update
