“Matplotlib 的问题是使用 fc-list 构建字体缓存.这可能需要一点时间."在 MacOS 上 [英] Problems with "Matplotlib is building the font cache using fc-list. This may take a moment." on MacoS

问题描述

我正在运行 OS X 10.11.3，并且我已经安装了 Anaconda3-2.5.0-MacOSX-x86_64.pkg，其中包括 Matplotlib 1.5.1.当我尝试使用以下内容在 Jupyter 中导入 Matplotlib 时:

I am running OS X 10.11.3, and I have installed Anaconda3-2.5.0-MacOSX-x86_64.pkg which includes Matplotlib 1.5.1. When I try to import Matplotlib in Jupyter with the following:

import matplotlib.pyplot as pp

我收到一条很长的错误消息，开头如下:

I get a very long error message, beginning with the following:

/Users/hgbauer/anaconda/lib/python3.5/site-packages/matplotlib/font_manager.py:273:用户警告:Matplotlib 正在使用 fc-list 构建字体缓存.这可能需要一点时间.

/Users/hgbauer/anaconda/lib/python3.5/site-packages/matplotlib/font_manager.py:273: UserWarning: Matplotlib is building the font cache using fc-list. This may take a moment.

无论我等待多长时间，消息都不会消失.

The message never goes away, no matter how long I wait.

我在一个相关的帖子中注意到:

I’ve noticed in a related thread:

matplotlib 导入时需要时间

这个问题可能需要删除 ~/.cache/matplotlib 的内容，但在这种情况下，Matplotlib 似乎是单独安装的，而不是作为 Anaconda 的一部分.

that the problem may require deleting the contents of ~/.cache/matplotlib, but in that situation, Matplotlib seems to have been installed separately rather than as a part of Anaconda.

我的问题是这样的:

如何访问 Anaconda 中的 ~/.cache/matplotlib 文件以删除内容?

How can I access the ~/.cache/matplotlib file in Anaconda in order to delete the contents?

任何建议将不胜感激.

推荐答案

要移除的文件在~/.matplotlib下，而不是~/.cache/matplotlib(出于迷信，您还想删除 ~/.cache/fontconfig，但错误的 .matplotlib 路径是大事)

The files to be removed are under ~/.matplotlib, rather than ~/.cache/matplotlib (you'll also want to remove ~/.cache/fontconfig out of superstition, but the wrong .matplotlib path was the big thing)

您应该在下次运行时再次看到该讨厌的消息，然后就不会再看到了.

You should see that pesky message again on your next run, then no more.
