我已经在python 2.6的Snow Leopard上安装了numpy/scipy/matplotlib。导入pylab似乎没有工作..在调用'import pylab'后,我得到以下内容:无法导入pylab?

什么给? pylab是否期待我没有的东西?它似乎是无法读取的东西,但我真的不明白这是什么..
Eh?那里没有实际的错误。你粘贴了整个回溯? – 2010-12-18 20:08:42
这就是整个回溯。它挂起,直到我的键盘中断它。也许我会让它坐下来看看是否会发生任何事情。这个模块是否需要很长时间才能导入? – coffee 2010-12-18 20:12:02
你有freetype 1.4安装吗?它是matplotlib所必需的。 – 2010-12-18 22:42:26
