How to install PyCairo 1.10 on Mac OSX with default python

不幸的是，我仍然遇到错误的头文件被发现的问题。请参阅下面的我的环境设置和waf构建的错误输出。我非常感谢任何指针。谢谢！

Answer 1

如果您尚未解决此问题，请尝试使用cairocffi：http://packages.python.org/cairocffi/

Answer 2

如果有人在OSX上仍然遇到py2cairo问题。我能够通过使用install_name_tool来运行。配置/构建过程正在运行并找到正确版本的python。但是编译后的二进制文件与python的错误版本相关联。这似乎是waf构建系统中的一个错误。

解决问题......

$ cd /usr/local/lib/python2.7/site-packages/cairo
$ otool -L _cairo.so 
_cairo.so:
    /Users/charlie/Downloads/py2cairo/build_directory/src/_cairo.so (compatibility version 0.0.0, current version 0.0.0)
    /usr/local/lib/libcairo.2.dylib (compatibility version 11403.0.0, current version 11403.2.0)
    /System/Library/Frameworks/Python.framework/Versions/2.7/Python (compatibility version 2.7.0, current version 2.7.6)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)
$ sudo install_name_tool -change /System/Library/Frameworks/Python.framework/Versions/2.7/Python /Library/Frameworks/Python.framework/Versions/2.7/Python _cairo.so 
$ otool -L _cairo.so 
_cairo.so:
    /Users/charlie/Downloads/py2cairo/build_directory/src/_cairo.so (compatibility version 0.0.0, current version 0.0.0)
    /usr/local/lib/libcairo.2.dylib (compatibility version 11403.0.0, current version 11403.2.0)
    /Library/Frameworks/Python.framework/Versions/2.7/Python (compatibility version 2.7.0, current version 2.7.6)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)

然后，您可以在运行waf脚本的python版本中导入和使用cairo。
