bashrcでPythonのバージョンを指定する方法

Posted at

はじめに

たまに使うので備忘録として残しておきます。

bashrcとは

bashを起動したときに読み込まれる設定ファイルです。

方法

$ python -V
Python 3.7.3
$ sudo vim ~/.bashrc

bashrcを開いて、以下を追記します。

bashrc
alias python=python3.8

以下のコマンドで設定を反映させます。

$ source ~/.bashrc

反映されているかどうか確認してみます。

$ python -V
Python 3.8.0

無事変更されました。
