Python 3發(fā)布3.5版本，看了PEP新特性，還是非常棒晴埂。安裝python3.5诞吱，并搭建響應的環(huán)境。
安裝python3.5
官網(wǎng)網(wǎng)站下載python3.5的mac安裝文件暴匠。安裝3的同時鞍恢，是不會影響2.X的，兩個版本可以共存啦。
創(chuàng)建 virtulenv 環(huán)境
安裝python3.5之后帮掉，3.x版本的包響應也在后面加個3弦悉，例如 pip和pip3

需要創(chuàng)建一個 虛擬環(huán)境，運行：
virtualenv -p python3 venv
該命令使用系統(tǒng)的python3來創(chuàng)建虛擬環(huán)境蟆炊，激活venv環(huán)境稽莉，查看python版本
?? python3? source venv/bin/activate
(venv)?? python3? which python/Users/ghost/Rsj217/python3/venv/bin/python
(venv)?? python3? which python3/Users/ghost/Rsj217/python3/venv/bin/python3
(venv)?? python3? pythonPython3.5.0(v3.5.0:374f501f4567, Sep122015,11:00:19)[GCC4.2.1(Apple Inc. build5666) (dot3)]?

此時虛擬環(huán)境使用的就是python3.5啦
安裝ipython適合3.5的版本
激活venv虛擬環(huán)境，使用 pip3直接安裝 ipython
(venv)?? python3? pip3installipython...
