Homebrew を指定のパスにインストールする
概要
MacPorts をメインに使っているので、Homebrew を標準ではないパス /opt/homebrew にインストールする。
install
$ sudo mkdir /opt/homebrew
$ sudo chown ${USER}:staff /opt/homebrew
$ cd /opt
$ curl -L https://github.com/Homebrew/homebrew/tarball/master | tar xz --strip 1 -C homebrew

$ cd /opt/homebrew
$ mv share/doc/homebrew docsインストール自体は↑で終わり。 /opt/homebrew/bin を環境変数 PATH に追加すれば brew コマンドが使える。
備考
基本的には上記のページと同じだが、そのままだと初回の brew update で↓のようにコケるため、 mv コマンドで /opt/homebrew/share/doc/homebrew を /opt/homebrew/docs へ移動している。
