Python 3发布3.5版本,看了PEP新特性,还是非常棒。安装python3.5,并搭建响应的环境。
安装python3.5
官网网站下载python3.5的mac安装文件。安装3的同时,是不会影响2.X的,两个版本可以共存啦。
创建 virtulenv 环境
安装python3.5之后,3.x版本的包响应也在后面加个3,例如 pip和pip3
☁ python3 python
python python3 python3.4m python3.5m-config
python-config python3-32 python3.4m-config pythons
python2.6 python3-config python3.5 pythonw2.6
python2.6-config python3.4 python3.5-32 pythonw2.7
python2.7 python3.4-32 python3.5-config
python2.7-config python3.4-config python3.5m
☁ python3 which python/usr/bin/python
☁ python3 which python3/usr/local/bin/python3
☁ python3 which pip/usr/local/bin/pip
☁ python3 which pip3/usr/local/bin/pip3
需要创建一个 虚拟环境,运行:
virtualenv -p python3 venv
该命令使用系统的python3来创建虚拟环境,激活venv环境,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)]
on darwin Type"help","copyright","credits"or"license"formore information.
>>>
此时虚拟环境使用的就是python3.5啦
安装ipython适合3.5的版本
激活venv虚拟环境,使用 pip3直接安装 ipython
(venv)☁ python3 pip3installipython...
(venv)☁ python3 which ipython/Users/ghost/Rsj217/python3/venv/bin/ipython
(venv)☁ python3 ipythonPython3.5.0
(v3.5.0:374f501f4567, Sep122015,11:00:19)Type "copyright", "credits" or "license" for more information.
