virtualenv 安装

1.Install pip and Virtualenv by issuing the following commands :

 $ sudo easy_install pip

 $ pip install --upgrade virtualenv

2.Create a Virtualenv environment by issuing a command of one of the following formats:

 $ virtualenv --system-site-packages [targetDirectory] # for Python 2.7

 $ virtualenv --system-site-packages -p python3 [targetDirectory] # for Python 3.n

3.Activate the Virtualenv environment by issuing one of the following commands:

$ cd [targetDirectory]

$ source ./bin/activate      # If using bash, sh, ksh, or zsh

$ source ./bin/activate.csh  # If using csh or tcsh

The preceding source command should change your prompt to the following:

(targetDirectory)$

4.Ensure pip ≥8.1 is installed:

 (targetDirectory)$ easy_install -U pip

5.退出virtualenv

 (targetDirectory)$ deactivate
