近來(lái)，在學(xué)習(xí)python的數(shù)據(jù)挖掘，需要安裝pygraphviz，與諸多麻煩：

注：我的系統(tǒng)是fedora 17beta版；python2.7.3

1、我首先直接安裝pygraphviz（easy_install），提示錯(cuò)誤：

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、按照以上錯(cuò)誤提示，我先安裝了Graphviz(yum install graphviz),木牛問(wèn)題；

3、接著再試著安裝libgraphviz-dev，安裝失敗；

4、轉(zhuǎn)而使用pip安裝，出現(xiàn)如下錯(cuò)誤：

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=Noneerror: None

使用pip安裝和easy_install所不同的是，其在主文件夾中會(huì)出現(xiàn)一個(gè)bulid文件夾，pygraphviz文件被下載緩存在此；

5、于是，修改pygraphviz文件夾中的setup.py文件夾，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'" //這個(gè)我們接下來(lái)會(huì)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

?上面這兩行需要注釋掉

# 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'

?上面這兩行需要取消注釋

# 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

? ?able to build it from this source. ?See

? ?http://networkx.lanl.gov/pygraphviz/reference/faq.html

這個(gè)不就是之前的錯(cuò)誤提示么？?

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、按照上述操作進(jìn)行修改，之后運(yùn)行?python setup.py install，但是依然出現(xiàn)錯(cuò)誤：“gcc -pthread -fno-strict-aliasing -DNDEBUG -O2 -g -pipe -Wp,-D_FORTIFY_SOURCE=2 -fs………………”?

7、應(yīng)該是gcc包缺失，于是乎，繼續(xù)安裝gcc；使用yum install gcc，出現(xiàn)錯(cuò)誤——一些依賴包無(wú)法安裝；

8、判斷可能是某些包版本不夠新，升級(jí)之(update-testing)

9、升級(jí)完之后，在安裝pygraphviz，出現(xiàn)錯(cuò)誤：“致命錯(cuò)誤，python.h沒(méi)有這個(gè)文件或目錄。”

10、然后，安裝包“python-dev”（yum install python-devel）；

11、easy_install 安裝，成功。import?pygraphviz，沒(méi)有報(bào)錯(cuò)，OK！
