在OS 10.6.7上安装pygraphviz-python 2.6(gcc-4.2错误) [英] Installing pygraphviz on os 10.6.7 - python 2.6 (gcc-4.2 error)

问题描述

我正在尝试在Mac OS 10.6.7上安装pygraphviz.我正在使用python 2.6.

I am trying to install pygraphviz on mac os 10.6.7. I am using python 2.6.

到目前为止，这是我所做的:

So far here is what I have done :

• 在以下位置下载了Graphviz 2.28: http://www.graphviz.org/Download_macos.php
• 使用以下命令下载pygraphviz:svn co <​​a href="https://networkx.lanl.gov/svn/pygraphviz/trunk" rel="nofollow"> https://networkx.lanl.gov/svn/pygraphviz/trunk pygraphviz
• 将目录更改为"pygraphviz"
• 取消注释进入setup.py脚本的路径(检查它是否正确；)): 所以脚本变成了:

• downloaded Graphviz 2.28 at : http://www.graphviz.org/Download_macos.php
• downloaded pygraphviz with the command: svn co https://networkx.lanl.gov/svn/pygraphviz/trunk pygraphviz
• Changed directory to "pygraphviz"
• uncommented the path into the setup.py script (checking that it was the right one ;) ) : so the script become :

setup.py:

# OSX, Linux, alternate location
library_path='/usr/local/lib/graphviz'
include_path='/usr/local/include/graphviz'

• 运行"python setup.py install"

，但是该过程失败并显示以下消息(请参见下面的代码): 错误:命令'gcc-4.2'失败，退出状态为1

but the process fails (see the code below) with the message : error: command 'gcc-4.2' failed with exit status 1

我尝试过:

• 取消安装重新安装Graphviz
• 安装Graphviz的开发版本
• 从python包索引(http://pypi.python.org/pypi/pygraphviz)下载pygraphviz，然后重新安装
• 其他安装方式:easy_install pygraphviz(给我同样的错误). macport(无法在我的计算机上安装)

我做错什么了吗?我该如何解决这种错误?

Am I doing something wrong? How can I solved this kind of error?

任何想法都会有很大帮助，

Any ideas would be a great help,

非常感谢

推荐答案

gcc-4.2是Apple开发人员工具包Xcode的一部分.您需要先安装它.应该有一个Xcode 3安装程序，其中包含Mac随附的软件恢复DVD，或者可能是硬盘本身或Mac OS X 10.6 DVD随附的软件恢复DVD，或者您可以从Apple Developer Connection网站下载版本(需要注册)，或者您可以从Mac Application Store购买较新的Xcode 4版本.如果您确实安装了Xcode 4，则可能需要在安装中添加export ARCHFLAGS='-arch i386 -arch x86_64'；否则，请执行以下步骤.有关更多信息，请参见此处.

gcc-4.2 is part of Apple's developers tools package, Xcode. You need to install it first. There should be an Xcode 3 installer with either the software restore DVD that came with your Mac or possibly on the hard disk itself or with the Mac OS X 10.6 DVD or you can download a version from the Apple Developer Connection website (registration required) or you can buy a version of the newer Xcode 4 from the Mac Application Store. If you do install Xcode 4, you will likely need to add an export ARCHFLAGS='-arch i386 -arch x86_64' to your install; see here for more info.
