Question

在执行handle_bar()时更新我的matplotlib版本import matplotlib.pyplot as plt后，我遇到与import matplotlib.pyplot hangs中所述相同的问题。

然而，the proposed solution对我不起作用;在fc-list中运行fc-list需要100％的CPU，并且在15分钟内无法完成。

我有以下配置：

Mac，运行OS 10.10.5（OS X Yosemite）
Python 2.7.5
matplotlib 1.4.3（1.3.1，该版本没有问题）

要更新我的matplotlib版本，我使用了：

~/.matplotlib

如果我现在重新运行此命令，我会

sudo pip install matplotlib

和Requirement already satisfied (use --upgrade to upgrade): matplotlib in /Library/Python/2.7/site-packages Requirement already satisfied (use --upgrade to upgrade): numpy>=1.6 in /Library/Python/2.7/site-packages (from matplotlib) Requirement already satisfied (use --upgrade to upgrade): pytz in /Library/Python/2.7/site-packages (from matplotlib) Requirement already satisfied (use --upgrade to upgrade): pyparsing!=2.0.0,>=1.5.6 in /Library/Python/2.7/site-packages (from matplotlib) Requirement already satisfied (use --upgrade to upgrade): python-dateutil in /Library/Python/2.7/site-packages (from matplotlib) Requirement already satisfied (use --upgrade to upgrade): nose>=0.11.1 in /Library/Python/2.7/site-packages (from matplotlib) Requirement already satisfied (use --upgrade to upgrade): six>=1.4 in /Library/Python/2.7/site-packages (from matplotlib) Requirement already satisfied (use --upgrade to upgrade): mock in /Library/Python/2.7/site-packages (from matplotlib) Requirement already satisfied (use --upgrade to upgrade): funcsigs in /Library/Python/2.7/site-packages (from mock->matplotlib) Requirement already satisfied (use --upgrade to upgrade): pbr>=0.11 in /Library/Python/2.7/site-packages (from mock->matplotlib)：

sudo pip install --upgrade matplotlib

我在Requirement already up-to-date: matplotlib in /Library/Python/2.7/site-packages Requirement already up-to-date: numpy>=1.6 in /Library/Python/2.7/site-packages (from matplotlib) Requirement already up-to-date: pytz in /Library/Python/2.7/site-packages (from matplotlib) Requirement already up-to-date: pyparsing!=2.0.0,>=1.5.6 in /Library/Python/2.7/site-packages (from matplotlib) Requirement already up-to-date: python-dateutil in /Library/Python/2.7/site-packages (from matplotlib) Requirement already up-to-date: nose>=0.11.1 in /Library/Python/2.7/site-packages (from matplotlib) Requirement already up-to-date: six>=1.4 in /Library/Python/2.7/site-packages (from matplotlib) Requirement already up-to-date: mock in /Library/Python/2.7/site-packages (from matplotlib) Requirement already up-to-date: funcsigs in /Library/Python/2.7/site-packages (from mock->matplotlib) Requirement already up-to-date: pbr>=0.11 in /Library/Python/2.7/site-packages (from mock->matplotlib)中有fontList.cache个文件。此文件是旧的（可追溯到2013年，因此比此更新尝试更早）。

问题：

尽管有~/.matplotlib文件，我应该运行fontList.cache，期望它在某个时候完成吗？
matplotlib是否希望在其他位置找到fc-list文件？也许我的matplotlib的安装/更新搞砸了一些路径 - 但是：matplotlib.get_cachedir()返回fontList.cache
文件名是否已更改？我应该重命名/Users/MyName/.matplotlib吗？
我不再拥有fontList.cache目录了。但是，/usr/X11/lin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）正在运行

sudo pip install matplotlib

和/或

sudo pip install --upgrade matplotlib

在编写问题时（捕获屏幕输出）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致电import matplotlib.pyplot as plt。

import matplotlib.pyplot - fc-list挂起
