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

python Mac

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。


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。

==> Caveats

This formula is keg-only, which means it was not symlinked into /usr/local.



OS X provides the BSD libedit library, which shadows libreadline.

In order to prevent conflicts when programs look for libreadline we are

defaulting this GNU Readline installation to keg-only.





Generally there are no consequences of this for you. If you build your

own software and it requires this formula, you'll need to add to your

build variables:



    LDFLAGS:  -L/usr/local/opt/readline/lib

    CPPFLAGS: -I/usr/local/opt/readline/include

hiroshi-no-MacBook-Air:~ hiroshi$  



完了したら、念のため確認として、次のよう打つと、すでにインストールされているよ、とメッセージが出てきます。


hiroshi-no-MacBook-Air:~ hiroshi$ brew install python3
Warning: python3-3.4.3_2 already installed


以上で、とりあえずpython3本体のインストールは完了です。
例によって、また上で出てきた処理のプロセスの全文を最後にまとめておきます。
