mac 安装python3.4、django

摘要: 最近开始研究python，mac安装pyhon有点麻烦，mac本身自带了python2.7。文章介绍下不删除python2.7 使用python3.4

一、获取root最高权限

重启机器，然后按住command+r进入恢复模式，打开终端输入csrutil disable。再重启机器

二、安装python

2.1 下载python-3.4.2-macosx10.6.pkg，并安装

2.2 将安装的3.4.2版本 的移到系统。

1、切换到root下。

2、

sudo mv /Library/Frameworks/Python.framework/Versions/3.4  /System/Library/Frameworks/Python.framework/Versions

3、

sudo chown -R root:wheel /System/Library/Frameworks/Python.framework/Versions/3.4

4、

sudo rm /usr/bin/pydoc
sudo rm /usr/bin/python
sudo rm /usr/bin/pythonw
sudo rm /usr/bin/python-config

5、

sudo ln -s /System/Library/Frameworks/Python.framework/Versions/3.4/bin/pydoc3.4 /usr/bin/pydoc
sudo ln -s /System/Library/Frameworks/Python.framework/Versions/3.4/bin/python3.4 /usr/bin/python
sudo ln -s /System/Library/Frameworks/Python.framework/Versions/3.4/bin/python3.4m-config /usr/bin/python-config
sudo ln -s /System/Library/Frameworks/Python.framework/Versions/3.4/bin/pip3 /usr/bin/pip3
sudo ln -s /System/Library/Frameworks/Python.framework/Versions/3.4/bin/easy_install-3.4  /usr/bin/easy_install-3.4

6、检验python

➜  / python

检验pip3

pip 1.5.6 from /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages (python 3.4)

三、elipse安装python插件

www.pydev.org/updates

勾选第一个



安装完后就多了pydev project



四、安装django

下载压缩包https://www.djangoproject.com/download/

解压后再文件夹中有setup.py

执行命令（先切换到root命令下）

4.11

#python setup.py install
............
省略
..........

4.12

➜  bin python

4.13

s sudo ln -s /System/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/Django-1.10.2-py3.4.egg/EGG-INFO/scripts/django-admin.py /usr/bin/django-admin.py

4.2新建一个工程

#sudo django-admin.py startproject mysite

然后将myite 文件夹中的setting.py 数据的NAME改成如下所示（由于现在还没有安装sqlit数据库）

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME':'',
}
}

4.3 启动项目

到

#ls
manage.py mysite
#./manage.py runserver
