Question

我使用的是Mac OS X 10.9。我已经安装了graphviz 2.36.0。

下载pygraphviz 1.2之后，我在setup.py中修改了变量＆＃34; library_path＆＃34;和＆＃34; include_path＆＃34;：

library_path='/usr/local/lib/graphviz'
include_path='/usr/local/include/graphviz'

当我尝试使用python setup.py install安装graphviz时，收到以下消息：

library_path=/usr/local/lib/graphviz
include_path=/usr/local/include/graphviz

有人知道如何解决这个问题吗？

确保您的XCode已更新为最新版本，然后尝试以下操作：

xcode-select --install

提示时安装命令行工具。然后尝试重建。
