如何在Matplotlib中修复ImportError

Question

我在运行雪豹的Mac上编译了matplotlib，只是发现在导入matplotlib.pyplot时遇到以下错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/pyplot.py", line 6, in <module>

    import matplotlib.font_manager as font_manager

    from matplotlib import ft2font
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/ft2font.so, 2): Symbol not found: _FT_Attach_File

我该如何解决？

众所周知，在OS X上构建matplotlib充满了链接到不匹配版本的库的问题，这些库可能位于系统目录/ usr / local，/ opt / local等。 这就是为什么在源代码发行版中有一个README.osx文件，建议您使用发行版中提供的make.osx文件来获取和编译库，并针对提取的副本构建matplotlib的原因。
