pyenv-virtualenv is a pyenv plugin that provides features to manage virtualenvs and conda environments for Python on UNIX-like systems.
Installation
- Check out pyenv-virtualenv into plugin directory
$(pyenv root) is the pyenv path that your installed- 将virtualenv 安装到pyenv插件目录
git clone https://github.com/pyenv/pyenv-virtualenv.git $(pyenv root)/plugins/pyenv-virtualenv

echo 'eval "$(pyenv virtualenv-init -)"' >> ~/.bashrc
Usage
Using pyenv virtualenv with pyenv
在pyen中使用virtual创建python2.7.18的虚拟环境
pyenv virtualenv 2.7.18 my-2.7.18
note: when create a virtualenv of 2.x with pyenv-virtualenv ,will download some modules,
注意：使用virtualenv创建2.x版本的虚拟环境的时候会下载一些模块，
pyenv virtualenv 2.7.18 my-2.7.18
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date.
