1. 安裝virtualenv
pip3 install virtualenv
由于不確定之前是否安裝過，查看一下
ubuntu@DESKTOP-AAH6KJH:~$ pip3 list
.........
virtualenv (15.0.1)
wheel (0.29.0)
........
You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
看到輸出信息，它建議我升級pip3，那我就從善如流了
ubuntu@DESKTOP-AAH6KJH:~$ pip3 install --upgrade pip

其實到現(xiàn)在這一步還沒有結束，因為還得需要創(chuàng)建虛擬環(huán)境的存放地址和設置環(huán)境變量
2.1創(chuàng)建虛擬環(huán)境目錄
mkdir $HOME/.virtualenvs
2.2添加環(huán)境變量信息
在~/.bashrc中添加以下信息
# virtualenv-wrapper path
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
source /usr/local/bin/virtualenvwrapper.sh

2.3重新加載環(huán)境變量
source ~/.bashrc
3.創(chuàng)建虛擬環(huán)境
mkvirtualenv -p python3 test
ubuntu@DESKTOP-AAH6KJH:~$ mkvirtualenv -p python3 test
