安装pyenv virtualenv

地址：https://github.com/pyenv/pyenv-virtualenv

1. Check out pyenv-virtualenv into plugin directory

   $ git clone https://github.com/pyenv/pyenv-virtualenv.git $(pyenv root)/plugins/pyenv-virtualenv

2. (OPTIONAL) Add pyenv virtualenv-init to your shell to enable auto-activation of virtualenvs. This is entirely optional but pretty useful. See "Activate virtualenv" below.

   $ echo 'eval "$(pyenv virtualenv-init -)"' >> ~/.bash_profile

   Fish shell note: Add this to your ~/.config/fish/config.fish

   status --is-interactive; and source (pyenv virtualenv-init -|psub)

   Zsh note: Modify your ~/.zshenv file instead of ~/.bash_profile.

   Pyenv note: You may also need to add eval "$(pyenv init -)" to your profile if you haven't done so already.

3. Restart your shell to enable pyenv-virtualenv$ exec "$SHELL"

　　　$ exec "$SHELL"
 
创建virtualenv:

pyenv  virtualenv  venv365

进入创建的env:

pyenv activate venv365

退出env

pyenv deactivate
