pyenvをシェルスクリプトから使いたい時がある、
pyenvを有効化するためにはsource ~/.bashrcを実行する必要があるので、スクリプトは以下のようになることが多い。
source ~/.bashrc
pyenv activate myenv
python -V
pyenv deactivate
pyenv activate myenv3.6.9
python -V
pyenv deactivate
pyenv activate myenv3.7.7
python -V
pyenv deactivate
しかし、これをそのままbash test.shのように実行するとエラーになる
$ bash test.sh

これはsourceがシェルスクリプトの中で有効になっていないためのようで、
source test.shで実行するとOK
$ source test.sh
