我的pygraphviz安装之路

近来，在学习python的数据挖掘，需要安装pygraphviz，与诸多麻烦：

注：我的系统是fedora 17beta版；python2.7.3

1、我首先直接安装pygraphviz（easy_install），提示错误：

1) You don't have Graphviz installed:
Install Graphviz (http://graphviz.org)

2) Your Graphviz package might incomplete.
Install the binary development subpackage (e.g. libgraphviz-dev or similar.)

3) You are using Windows
There are no PyGraphviz binary packages for Windows but you might be
able to build it from this source. See
http://networkx.lanl.gov/pygraphviz/reference/faq.html

2、按照以上错误提示，我先安装了Graphviz(yum install graphviz),木牛问题；

3、接着再试着安装libgraphviz-dev，安装失败；

4、转而使用pip安装，出现如下错误：

Your graphviz installation could not be found.

Either the graphviz package is missing on incomplete
(binary packages graphviz-dev or graphviz-devel missing?).

If you think your installation is correct you will need to manually
change the include_path and library_path variables in setup.py to
point to the correct locations of your graphviz installation.

The current setting of library_path and include_path is:
library_path=None
include_path=None

error: None

使用pip安装和easy_install所不同的是，其在主文件夹中会出现一个bulid文件夹，pygraphviz文件被下载缓存在此；

5、于是，修改pygraphviz文件夹中的setup.py文件夹，我使用的是vi；

在其中可以看到：

from glob import glob

import os

import sys

if os.path.exists('MANIFEST'): os.remove('MANIFEST')

 

from distutils.core import setup, Extension

 

from setup_extra import pkg_config, dotneato_config

 

if sys.argv[-1] == 'setup.py':

    print "To install, run 'python setup.py install'" //这个我们接下来会用到的；

    print

 

if sys.version_info[:2] < (2, 4):

    print "PyGraphviz requires Python version 2.4 or later (%d.%d detected)." % \

          sys.version_info[:2]

    sys.exit(-1)

 

library_path=None

include_path=None

 上面这两行需要注释掉

# If the setup script couldn't find your graphviz installation you can

# specify it here by uncommenting these lines or providing your own:

# You must set both 'library_path' and 'include_path'

 

# Linux, generic UNIX

#library_path='/usr/lib/graphviz'

#include_path='/usr/include/graphviz'

 

# OSX, Linux, alternate location

#library_path='/usr/local/lib/graphviz'

#include_path='/usr/local/include/graphviz'

 上面这两行需要取消注释

# OSX (Fink)

#library_path='/sw/lib/graphviz'

#include_path='/sw/include/graphviz'

 

# OSX (MacPorts)

#library_path='/opt/local/lib/graphviz'

#include_path='/opt/local/include/graphviz'

 

# Windows

# Unknown

 

# Attempt to find Graphviz installation

if library_path is None and include_path is None:

    print "Trying pkg-config"

    include_path,library_path=pkg_config()

 

if library_path is None and include_path is None:

    print "Trying dotneato-config"

    include_path,library_path=dotneato_config()

 

if library_path is None or include_path is None:

    print 

    print  """Your Graphviz installation could not be found.

 

1) You don't have Graphviz installed:

   Install Graphviz (http://graphviz.org)

 

2) Your Graphviz package might incomplete.

   Install the binary development subpackage (e.g. libgraphviz-dev or similar.)

 

3) You are using Windows

   There are no PyGraphviz binary packages for Windows but you might be

这个不就是之前的错误提示么？ 

If you think your installation is correct you will need to manually

change the include_path and library_path variables in setup.py to

point to the correct locations of your graphviz installation.

6、按照上述操作进行修改，之后运行 python setup.py install，但是依然出现错误：“gcc -pthread -fno-strict-aliasing -DNDEBUG -O2 -g -pipe -Wp,-D_FORTIFY_SOURCE=2 -fs………………” 

7、应该是gcc包缺失，于是乎，继续安装gcc；使用yum install gcc，出现错误——一些依赖包无法安装；

8、判断可能是某些包版本不够新，升级之(update-testing)

9、升级完之后，在安装pygraphviz，出现错误：“致命错误，python.h没有这个文件或目录。”

10、然后，安装包“python-dev”（yum install python-devel）；

11、easy_install 安装，成功。import pygraphviz，没有报错，OK！
