在Mountain Lion上成功安装后，Matplotlib无法正常工作 [英] Matplotlib not working after successful installation on Mountain Lion

问题描述

我安装了 matplotlib 网站上列出的所有依赖项.但是，它仍然不起作用.我在下面列出了python堆栈跟踪并安装了python软件包.那么，我该如何解决这个问题?

I installed all the dependencies listed on the matplotlib website. However, it still doesn't work. I listed the python stack trace and installed python packages below. So, how can I solve this problem?

Python堆栈跟踪:

推荐答案

这是 matplotlib 1.4.x 中的一个错误，其中 fontmanager.py 试图导入名称包含非 ascii 的字体字符.

This is a bug in matplotlib 1.4.x where fontmanager.py is trying to import a font whose name contains a non-ascii character.

您的问题类似于这个给出的补丁不会帮助你，因为你安装了 matplotlib 1.4.x 而不是 1.3.0.

Your question is similar to this one but the patch given won't help you because you have matplotlib 1.4.x installed and not 1.3.0.

正如上面问题中所建议的，您可以查看您的字体列表并尝试删除带有非 ascii 字符的字体.特别注意 Æ.

As suggested in the question above, you can take a look at your font list and try removing fonts with non ascii characters. Look especially for Æ.

或者，您可以尝试升级到似乎是已修复:

Or, you can try upgrading to the development version of matplotlib where it seems to be fixed:

pip install git+https://github.com/matplotlib/matplotlib.git#egg=matplotlib-dev
