Mac下如何安装Django呢？

安装步骤如下

1.Django安装前，先安装python,再安装pip

ksnowlv@ksnowlvdeMacBook-Pro~/Movies/python server$sudo easy_install pip

2.然后安装Django：

ksnowlv@ksnowlvdeMacBook-Pro~/Movies/python server$sudo pip install Django

3.安装出错，如何解决呢？方案是添加两个环境变量:

export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments

示例如下:

ksnowlv@ksnowlvdeMacBook-Pro~/Movies/python server$export CFLAGS=-Qunused-arguments
ksnowlv@ksnowlvdeMacBook-Pro~/Movies/python server$export CPPFLAGS=-Qunused-arguments
ksnowlv@ksnowlvdeMacBook-Pro~/Movies/python server$sudo pip install Django

这个过程好折腾，找半天解决方案。希望大家多注意!!!

4.验证下是否安装成功

ksnowlv@ksnowlvdeMacBook-Pro~/Movies/python server$python
Python 2.7.5 (default, Mar  9 2014, 22:15:05) 
[GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>> print django.get_version()
1.6.5
#输出1.6.5 表示当前最新版本为1.6.5，表示已经安装成功
>>> ^D
#退出python control + D
ksnowlv@ksnowlvdeMacBook-Pro~/Movies/python server$  

终于安装成功,大功告成!
