一、安装pip包管理器

• Ps:我这里使用的是deepin的15.9版本，非原生ubuntu
• 在这里默认是没有安装pip包管理器的需要手动安装

python@python:~$ sudo apt install python3-pip

二、安装virtualenv及virtualenvwrapper

sudo pip3 install virtualenv
sudo pip3 install virtualenvwrapper
sudo apt install virtualenv

三、配置~/.bashrc

source ~/.bashrc

在最后添加如下内容：

export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/bin/virtualenv
source /usr/local/bin/virtualenvwrapper.sh

使配置生效

python@python:~$ source ~/.bashrc 
virtualenvwrapper.user_scripts creating /home/python/HOME/.virtualenvs/premkproject
virtualenvwrapper.user_scripts creating /home/python/HOME/.virtualenvs/postmkproject
virtualenvwrapper.user_scripts creating /home/python/HOME/.virtualenvs/initialize
virtualenvwrapper.user_scripts creating /home/python/HOME/.virtualenvs/premkvirtualenv
virtualenvwrapper.user_scripts creating /home/python/HOME/.virtualenvs/postmkvirtualenv
virtualenvwrapper.user_scripts creating /home/python/HOME/.virtualenvs/prermvirtualenv
virtualenvwrapper.user_scripts creating /home/python/HOME/.virtualenvs/postrmvirtualenv
virtualenvwrapper.user_scripts creating /home/python/HOME/.virtualenvs/predeactivate
virtualenvwrapper.user_scripts creating /home/python/HOME/.virtualenvs/postdeactivate
virtualenvwrapper.user_scripts creating /home/python/HOME/.virtualenvs/preactivate
virtualenvwrapper.user_scripts creating /home/python/HOME/.virtualenvs/postactivate
virtualenvwrapper.user_scripts creating /home/python/HOME/.virtualenvs/get_env_details

四、创建虚拟环境

mkvirtualenv py_django --python=/usr/bin/python3
#指定Python版本为python3虚拟环境名为：py_django

五、激活虚拟环境

workon py_django

六、退出及删除虚拟环境

#退出
deactivate
#删除
rmvirtualenv
