pythonのバージョンが切り替わらない

More than 3 years have passed since last update.

プリインストールされている2.Xのpythonを、3.xにバージョンアップしようと思ったところ、少し引っかかったのでメモ。

バージョンを変更してみる

新しいバージョンをインストール、確認

$ pyenv install 3.6.0
$ pyenv versions
system
* 3.6.0 (set by ・・・・

新しくディレクトリを作成後、そこでlocalオプションでバージョン切り替え。
のつもりがうまくいかず。。
$ pyenv local 3.6.0
$ python -V
Python 2.7.10

対処法

~/.bash_profileに以下を追記

export PATH="$HOME/.pyenv/shims:$PATH"

.bash_profileを適用
source ~/.bash_profile

これでPathが通ったので無事バージョンが切り替えられました!
$ python -V
Python 3.6.0
