エラーその1

内容
$ brew update
Error: /usr/local must be writable!
解決方法

/usr/local 以下のパーミッションを変更する

素人がEl Capitanにアップデートしてみたやつ。 - Qiita

$ sudo chown -R $(whoami):admin /usr/local

解決方法

brew prune を行う

Homebrewでbrew updateしたら/usr/local/Library/ENV/scm/git: No such file or directoryと言われてしまう - Smoky God Express

$ brew prune
Pruned 0 symbolic links and 2 directories from /usr/local

蛇足

ついでに、サブコマンドのコマンド入力補完設定方法をメモっておく

completion の ソース入手

$ curl https://raw.githubusercontent.com/Bash-it/bash-it/master/completion/available/tmux.completion.bash > ~/.tmux.completion.bash

~/.bash_profile に編集

source ~/.tmux.completion.bash
