python_selectで簡単バージョン切り替え
Pythonのバージョンを切り替えてくれるpython_selectを入れてみた。
インストール
sudo port install python_select
切り替え
% python_select usage: python_select [-n] [-d] [-r] [-h] [-v] version -n Show commands to do selection but do not execute them. -d Show debug messages during execution -h Display this help info. -v Display version of python_select. -l List available options for version. -s Show the currently selected version % python_select -l Available versions: current none python25 python26-apple python31 % python_select -s python26-apple % python --version Python 2.6.1 % sudo python_select python31 Selecting version "python31" for python % python --version Python 3.1.1 % sudo python_select current Selecting version "current" for python % python --version Python 3.1.1 % sudo python_select none Selecting version "none" for python % python --version Python 2.6.1 % python_select -s none
noneはpython_selectによる変更を無効化する?インストール直後はnoneだったのかも。
currentの存在意義はよくわからん。
