Python 如何使XKCD字体在matplotlib中工作

我试图重现这个例子

代码就在那一页和这篇文章的末尾

我正在使用的系统 我正在使用的Python版本 Matplotlib版本 系统上安装的字体 这表明我已经安装了字体

$ fc-list | grep "Humo"
/usr/share/fonts/Humor-Sans-1.0.ttf: Humor Sans:style=Regular
/home/vco/.fonts/Humor-Sans-1.0.ttf: Humor Sans:style=Regular

我正在使用的Matplotlib后端

输出误差 我遵循了一个帖子的指示

python输出错误：

/home/vco/anaconda/envs/math_general/lib/python3.5/site-packages/matplotlib/font_manager.py:1288:
UserWarning: findfont: Font family ['Humor Sans', 'Comic Sans MS'] not
found. Falling back to Bitstream Vera Sans

  (prop.get_family(), self.defaultFamily[fontext]))

/home/vco/anaconda/envs/math_general/lib/python3.5/site-packages/matplotlib/font_manager.py:1298:

  Sans:style=normal:variant=normal:weight=400:stretch=normal:size=medium.
  Returning /usr/share/matplotlib/mpl-data/fonts/ttf/cmtt10.ttf UserWarning)

我还尝试将下载的字体移动到

/usr/share/matplotlib/mpl-data/fonts/ttf

但是仍然有以下错误

/home/vco/anaconda/envs/math_general/lib/python3.5/site-packages/matplotlib/font_manager.py:1288: UserWarning: findfont: Font family ['Humor Sans', 'Comic Sans MS'] not found. Falling back to Bitstream Vera Sans

尝试删除Matplotlib缓存，看看它是否有效（即，

rm-r~/.cache/Matplotlib

）

就我而言，它解决了问题：

user@host:~$ ./xkcd.py
/home/user/.pyenv/versions/3.7.1/lib/python3.7/site-packages/matplotlib/font_manager.py:1241:
UserWarning: findfont: Font family ['xkcd', 'Humor Sans', 'Comic Sans MS'] not found.
Falling back to DejaVu Sans. (prop.get_family(), self.defaultFamily[fontext]))
user@host:~$ rm -r ~/.cache/matplotlib
user@host:~$ ./xkcd.py
user@host:~$

如果在安装HumorSans字体后仍然看到错误，我建议您运行：

import matplotlib
matplotlib.font_manager._rebuild()

---

它将重建字体缓存。

检查答案。@lincolnfrias什么，我在帖子中提到的第一件事是什么？我看过；）哦，对不起。我指出这一点是因为在我的例子中，删除.config中的matplolib缓存解决了这个问题。@lincolnfrias“在我的例子中…”<这是指什么？您已经测试了我在类似设置中发布的代码，或者这是您所指的另一件事？Cheers@MartinThoma不，我还没有解决这个问题，也许它会被加入到千年奖的问题中
