django学习之pythonbrew部署开发环境
融合了virtualenv,创建隔离环境更方便快捷
具有pyenv的所拥有的所有功能(个人感觉更强悍)
使用示例
列出可安装的 python 版本:
pythonbrew list --know
安装某个版本的 python :
pythonbrew install 2.7.3
删除已安装的某版本的 python :
pythonbrew uninstall 2.7.3
列出已安装的 python 版本(当前使用的版本后会用星号标记):
pythonbrew list
使用某个版本的 python (仅当前终端窗口有效):
pythonbrew use 2.7.3
切换到某个版本的 python (一直有效):
pythonbrew switch 2.7.3
清理陈旧的源码目录和档案包:
pythonbrew cleanup
升级到pythonbrew到最新版本:
pythonbrew update
禁用pythonbrew(即切换回原始环境):
pythonbrew off
创建python隔离环境(借助virtualenv):

创建一个名为flask的虚拟坏境并切换到这个虚拟环境下面

在这个虚拟环境下安装版本为1.6的django
