综合

一. window环境安装

1. 安装python 2.7.3 （win7 64）

下载python-2.7.3.amd64.msi

2. 安装easy_install

3. 安装其他功能包

如：easy_install MySQL-python

easy_install -U DBUtils

问题解决：

.没有gcc编译环境

unable to find vcvarsall.bat

解决方法：安装编译环境（一个老外的帖子）

1) First ofall download MinGW. Youneed g++compiler and MingW make in setup.

2) If youinstalled MinGW for example to “C:\MinGW” then add “C:\MinGW\bin”to your PATH in Windows.（安装路径加入环境变量）

3) Now startyour Command Prompt and go the directory where you have your setup.py residing.

4) Last andmost important step:

setup.py install build --compiler=mingw32

或者在setup.cfg中加入：
[build]
compiler = mingw32

4. 已编译版本安装

MySQL-python-1.2.3.win-amd64-py2.7.exe

5. api文档地址 2.7
http://docs.python.org/2/py-modindex.html
二. linux环境

1. 下载DBUtils1.1
wget http://www.webwareforpython.org/downloads/DBUtils/DBUtils-1.1.tar.gz
2. 解压
tar -xvf DBUtils-1.1.tar.gz

3. 安装DBUtils1.1
cd DBUtils-1.1
python setup.py install

4. 安装MySQL-python
yum install MySQL-python

5. 安装pip

yum install python-pip

检查

which pip-python

三. 数据挖掘环境

安装activepython，自带了easy_install

easy_install numpy

easy_install networkx

easy_install twitter

easy_install nltk

easy_install BeautifulSoup

四. 安装pil

windows64位

下载Pillow-2.0.0.win-amd64-py2.7.exe

下载地址：http://www.lfd.uci.edu/~gohlke/pythonlibs/

导入

windows用：from PIL import Image

linux用：import Image

centos 64位

wget "http://effbot.org/downloads/Imaging-1.1.7.tar.gz"

tar xvfz Imaging-1.1.7.tar.gz

cd Imaging-1.1.7

python setup.py build_ext -i

如果出错：command 'gcc' failed with exit status 1，需要安装python一个插件

yum install python-devel

如果使用pil时出错：decoder jpeg not available，则安装jpeg库

yum install libjpeg-devel

下载FREETYPE2库

wget "http://sourceforge.net/projects/freetype/files/freetype2/2.4.8/freetype-2.4.8.tar.gz"

tar zxvf freetype-2.4.8.tar.gz

cd freetype-2.4.8

make

make install

安装png库

yum install zlib zlib-devel

重新安装

python setup.py build_ext -i

python setup.py install

使用：

import sys
sys.path.append("/root/Imaging-1.1.7/PIL")
import Image

五. 安装python magick

window安装

1. 下载imagemagick并安装
http://www.imagemagick.org/script/binary-releases.php#windows
2. 安装wand

easy_install Wand

3. 示例代码

#!/usr/bin/env python
from urllib2 import urlopen
from wand.image import Image

def dowloadImg(url):
f = urlopen(url);
return Image(file=f);

def resizeImg(img, width, height):
print img.size
img.resize(width, height)
img.save(filename = 'temp_%s_%s.%s' % (img.width, img.height, img.format))

if __name__ == '__main__':
img = dowloadImg('http://xxx.com/xxx.png')
resizeImg(img,64,64)
resizeImg(img,48,48)

centos

1. 安装imagemagick

yum update

yum install ImageMagick-devel

2. 安装 Wand

pip-python install Wand
