import matplotlib.pyplot - fc-list挂起

Question

我正在遇到import matplotlib.pyplot hangs中描述的相同问题，在执行import matplotlib.pyplot as plt时更新我的​​matplotlib版本fc-list挂起。

但是，the proposed solution不适合我;在fc-list中运行~/.matplotlib需要100％的CPU并且在15分钟内没有完成。

我有以下配置：

• Mac，运行OS 10.10.5（OS X约塞米蒂）
• Python 2.7.5
• matplotlib 1.4.3（原为1.3.1，该版本没有问题）

要更新我的matplotlib版本，我使用了：

sudo pip install matplotlib

如果我现在重新运行此命令，我会得到

和sudo pip install --upgrade matplotlib：

我在fontList.cache有一个~/.matplotlib文件。此文件是旧的（可追溯到2013年，因此比此更新尝试更早）。

问题：

1. 尽管fontList.cache文件，我应该运行fc-list，期望它在某个时候完成？
2. matplotlib是否希望在其他位置找到fontList.cache文件？也许我的安装/更新matplotlib搞砸了一些路径 - 但是：matplotlib.get_cachedir()返回/Users/MyName/.matplotlib
3. 文件名是否已更改？我应该重命名fontList.cache吗？
4. 我再也没有/usr/X11/lindirectory了。然而，fc-list仍然可以进入无限循环as suggested？

Answer 1

发布问题后我无法重现问题。

我怀疑（重新）跑步

sudo pip install matplotlib

和/或

sudo pip install --upgrade matplotlib

在编写问题（捕获屏幕输出）时修复了以前存在的问题。

fc-list现在在2分钟内完成;虽然它没有创建一个新的fontList.cache文件。

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