python 相关安装和配置
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
