Python 开发的过程中，工程一多，难免会碰到不同的工程依赖不同版本的库的问题；亦或者是在开发过程中不想让物理环境里充斥各种各样的库，引发未来的依赖灾难。此时，我们需要对于不同的工程使用不同的虚拟环境来保持开发环境以及宿主环境的清洁。virtualenv是一个可以帮助我们管理不同 Python 环境,可以在系统中建立多个不同并且相互不干扰的虚拟环境。一 安装、配置virtualenv
1.1下载包
1.2 安装virtualenv
1.3 创建独立的虚拟环境
created virtual environment CPython3.6.9.final.0-64 in 371ms
creator CPython3Posix(dest=/root/PycharmProjects/drfdemo/venv, clear=False, global=False)
seeder FromAppData(download=False, pip=latest, setuptools=latest, wheel=latest, via=copy, app_data_dir=/root/.local/share/virtualenv/seed-app-data/v1.0.1)
activators BashActivator,CShellActivator,FishActivator,PowerShellActivator,PythonActivator,XonshActivator
drwxr-xr-x 4 root root 4096 4月 12 10:28 venv/
1.4 虚拟环境简单操作
Package Version
---------- -------
Django 1.9.8
pip 20.0.2
setuptools 46.1.3
wheel 0.34.2
virtualenv 的一个最大的缺点就是：bin 目录下 source 一下 activate，这就需要我们记住每个虚拟环境所在的目录。
二 虚拟环境virtualenvwrapper
2.1 安装虚拟环境virtualenvwrapper
export WORKON_HOME=~/Envs # 设置virtualenv的统一管理目录, 以后自动下载的虚拟环境，全部都放在这
export VIRTUALENVWRAPPER_VIRTUALENV_ARGS=‘‘ # 添加virtualenvwrapper的参数，生成干净隔绝的环境
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
2.2 创建一个虚拟环境简单使用
created virtual environment CPython3.6.9.final.0-64 in 325ms
