Macでpython3の環境構築2---python3本体のインストール---

前回「MacでPython3の環境構築１---Homebrewのインストール---」ではHomebrewをインストールしたので、次にpython3をインストールします。

とは言っても、Homebrewさえインストールしてしまえば、あとはコマンドを一回打つだけなのですが。

ターミナルを開いて、カーソルが点滅しているところに以下のように打ちます。

  1. hiroshi-no-MacBook-Air:~ hiroshi$ brew install python3       # 「brew install python3」というコマンドを打ち、returnを押す。

そうすると、以下のような処理が走りますので、完了するまで待つだけです。
  1. ==> Installing dependencies for python3: readline, sqlite, gdbm, openssl, xz

  3. ==> Installing python3 dependency: readline

以上で、とりあえずpython3本体のインストールは完了です。
