Failed to import pylab?

Question

I installed numpy / scipy / matplotlib on Snow Leopard using python 2.6. Importing pylab does not seem to work. After calling import pylab, I get the following:

File "<stdin>", line 1, in <module>
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/pylab.py", line 1, in <module>
    from matplotlib.pylab import *
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/pylab.py", line 216, in <module>
    from matplotlib import mpl  # pulls in most modules
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/mpl.py", line 2, in <module>
    from matplotlib import axis
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/axis.py", line 10, in <module>
    import matplotlib.font_manager as font_manager
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/font_manager.py", line 1339, in <module>
    _rebuild()
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/font_manager.py", line 1326, in _rebuild
    fontManager = FontManager()
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/font_manager.py", line 1004, in __init__
    self.ttffiles = findSystemFonts(paths) + findSystemFonts()
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/font_manager.py", line 343, in findSystemFonts
    for f in get_fontconfig_fonts(fontext):
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/font_manager.py", line 301, in get_fontconfig_fonts
    output = pipe.communicate()[0]
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 683, in communicate
    stdout = self.stdout.read()

What gives? Is pylab waiting for something I don't have? He seems to be unable to read something, but I really do not understand what it is.

Answer 1

Just wait. The problem is that fc-list takes a long time to run for the first time, and it seems to be hanging; but if you wait 2-3 minutes, it will be finished, and then it will work faster after that.

fc-list root, -; , , !

Answer 2

from pylab import *

pylab python env. .
