Python Matplotlib已停止工作，并出现很长的错误。。。有什么建议吗？

我一直在尝试以不同的方式安装numpy/scipy，并确保我有lapack/blas支持，但不知怎么搞的把事情搞砸了，所以现在当我做一个简单的绘图时，它不起作用，我需要键入+c来中断，然后得到这个冗长的错误消息。有什么解决办法吗？我已经安装和卸载了python/numpy/scipy/matplotlib好几次了，但都没有成功

我在Ubuntu 14.04上

or send an email to the mailing list at ipython-dev@scipy.org

You can print a more detailed traceback right now with "%tb", or use "%debug"
to interactively debug it.

Extra-detailed tracebacks for bug-reporting purposes can be enabled via:

编辑：

引发错误的代码是：

from matplotlib import pyplot as plt
plt.ion()
plt.plot(range(10))
# window doesn't show anything hangs, I end up typing <ctrl>+c and then the error appears

从matplotlib导入pyplot作为plt
plt.ion（）
plt.绘图（范围（10））
#窗口没有显示任何挂起，我最后键入+c，然后出现错误

您能发布引起上述错误的代码吗？是的，添加了。。。虽然不确定它有多有用…通过Anaconda安装？没有。。通过

apt-get

虽然在从

apt-get

卸载后尝试通过pip进行安装，但也失败了。它报告的错误是键盘中断，这意味着您

Ctr-c

'd程序。看起来它正在重建字体缓存，这可能需要一段时间。试着多一点耐心。
