こんな感じでインストール完了。
とりあえずセルフチェックしてみる。

1
2
$ brew doctor
Your system is ready to brew.

brewコマンドが叩けて、チェックも問題ないので完了。

もし、brewコマンドが使えなかったらパスが通ってないかもしれないので、次のようにしてみてください。

・環境変数の確認

1
$ echo $PATH

・結果（例）

1
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

「/usr/local/bin」がなかったら次のコマンドを実行

1
2
$ echo export PATH='/usr/local/bin:$PATH' >> ~/.zshrc
source ~/.zshrc

※bash等の場合は適宜変更してください
