import matplotlib.pyplot - fc-list 挂起

Question

在更新我的 matplotlib 版本 import matplotlib.pyplot as plt 后，我遇到了与 import matplotlib.pyplot hangs 中所述相同的问题，在执行 fc-list 时挂起。

但是，the proposed solution 对我不起作用；运行ning fc-list in ~/.matplotlib 占用 100% CPU 且未在 15 分钟内完成。

我有以下配置：

Mac, 运行宁 OS 10.10.5 (OS X Yosemite)
Python 2.7.5
matplotlib 1.4.3（是 1.3.1，那个版本没问题）

为了更新我的 matplotlib 版本，我使用了：

sudo pip install matplotlib

如果我现在重新运行这个命令，我得到

和sudo pip install --upgrade matplotlib：

我在 ~/.matplotlib 中有一个 fontList.cache 文件。这个文件是旧的（可以追溯到 2013 年，因此比这次更新尝试更早）。

问题：

尽管有 fontList.cache 文件，我是否应该运行 fc-list 期望它在某个时候完成？
matplotlib 是否希望在其他位置找到 fontList.cache 文件？也许我的 matplotlib install/update 搞砸了一些路径 - 但是：matplotlib.get_cachedir() returns /Users/MyName/.matplotlib
文件名改了吗？我应该重命名 fontList.cache 吗？
我没有 /usr/X11/lin 目录了。但是，难道fc-list还会进入死循环吗as suggested？

Answer 1

发布问题后无法重现问题。

我怀疑（重新）运行

sudo pip install matplotlib

and/or

sudo pip install --upgrade matplotlib

在编写问题（以捕获屏幕输出）时修复了之前存在的问题。

fc-list 现在在 2 分钟内完成；尽管它没有创建新的 fontList.cache 文件。

我现在可以像以前一样打电话给 import matplotlib.pyplot as plt。

import matplotlib.pyplot - fc-list 挂起

import matplotlib.pyplot - fc-list hangs
