导入matplotlib.pyplot挂起
我试图让matplotlib在OS X 10.8.4上运行。 我已经安装了matplotlib和依赖（libping，freetype，numpy，scipy）。 我能够导入matplotlib就好了。 但是，如果我尝试导入matplotlib.pyplot，它只是挂起。 没有错误，只是没有任何反应。
>>> import matplotlib.pyplot 我等了20分钟，什么也没有发生。 我正在使用1.2.1版本，但即使卸载，并尝试版本1.2.0，但无济于事。 我已经看到了关于matplotlib.pyplot导入错误的一些问题，但没有任何地方挂起。 然后我尝试使用Enthought / Canopy python发行版来工作，但同样是悬而未决的问题。 这是我看到如果我杀了导入：
Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Applications/Canopy.app/appdata/canopy-1.0.3.1262.macosx-x86_64/Canopy.app/Contents/lib/python2.7/site-packages/matplotlib/pyplot.py", line 26, in <module> from matplotlib.figure import Figure, figaspect File "/Applications/Canopy.app/appdata/canopy-1.0.3.1262.macosx-x86_64/Canopy.app/Contents/lib/python2.7/site-packages/matplotlib/figure.py", line 34, in <module> import matplotlib.colorbar as cbar File "/Applications/Canopy.app/appdata/canopy-1.0.3.1262.macosx-x86_64/Canopy.app/Contents/lib/python2.7/site-packages/matplotlib/colorbar.py", line 29, in <module> import matplotlib.collections as collections File "/Applications/Canopy.app/appdata/canopy-1.0.3.1262.macosx-x86_64/Canopy.app/Contents/lib/python2.7/site-packages/matplotlib/collections.py", line 23, in <module> import matplotlib.backend_bases as backend_bases File "/Applications/Canopy.app/appdata/canopy-1.0.3.1262.macosx-x86_64/Canopy.app/Contents/lib/python2.7/site-packages/matplotlib/backend_bases.py", line 37, in <module> import matplotlib.widgets as widgets File "/Applications/Canopy.app/appdata/canopy-1.0.3.1262.macosx-x86_64/Canopy.app/Contents/lib/python2.7/site-packages/matplotlib/widgets.py", line 17, in <module> from lines import Line2D File "/Applications/Canopy.app/appdata/canopy-1.0.3.1262.macosx-x86_64/Canopy.app/Contents/lib/python2.7/site-packages/matplotlib/lines.py", line 25, in <module> from matplotlib.font_manager import FontProperties File "/Applications/Canopy.app/appdata/canopy-1.0.3.1262.macosx-x86_64/Canopy.app/Contents/lib/python2.7/site-packages/matplotlib/font_manager.py", line 1335, in <module> _rebuild() File "/Applications/Canopy.app/appdata/canopy-1.0.3.1262.macosx-x86_64/Canopy.app/Contents/lib/python2.7/site-packages/matplotlib/font_manager.py", line 1322, in _rebuild fontManager = FontManager() File "/Applications/Canopy.app/appdata/canopy-1.0.3.1262.macosx-x86_64/Canopy.app/Contents/lib/python2.7/site-packages/matplotlib/font_manager.py", line 980, in __init__ self.ttffiles = findSystemFonts(paths) + findSystemFonts() File "/Applications/Canopy.app/appdata/canopy-1.0.3.1262.macosx-x86_64/Canopy.app/Contents/lib/python2.7/site-packages/matplotlib/font_manager.py", line 317, in findSystemFonts for f in get_fontconfig_fonts(fontext): File "/Applications/Canopy.app/appdata/canopy-1.0.3.1262.macosx-x86_64/Canopy.app/Contents/lib/python2.7/site-packages/matplotlib/font_manager.py", line 274, in get_fontconfig_fonts output = pipe.communicate()[0] File "/Applications/Canopy.app/appdata/canopy-1.0.3.1262.macosx-x86_64/Canopy.app/Contents/lib/python2.7/subprocess.py", line 746, in communicate stdout = _eintr_retry_call(self.stdout.read) File "/Applications/Canopy.app/appdata/canopy-1.0.3.1262.macosx-x86_64/Canopy.app/Contents/lib/python2.7/subprocess.py", line 478, in _eintr_retry_call return func(*args) KeyboardInterrupt
当我使用OS X附带的默认python 2.7时，输出是一样的。
UPDATE
允许import matplotlib.pyplot运行几个小时，然后中断导入现在给我这个输出：

有没有人知道什么是recursionfor x in walk(new_path, topdown, onerror, followlinks):可能表示？
您可以通过执行以下操作在Mac OS X Mavericks和Yosemite上解决问题：
cd ~/.matplotlib/ fc-list # Should take a couple minutes.
在fc-list完成运行后，您将能够使用import matplotlib.pyplot as plt导入包。 这是解决scheme的github问题 。 看来这个bug与字体caching有关。
我想清楚发生了什么事。 希望解决scheme对其他人有用。 在/usr/X11/lib文件夹中有一个指向自己的目录的符号链接。 这似乎创造了一个无限循环。 当我删除链接，导入工作。
