这表明我已经安装了字体。

尝试删除Matplotlib缓存并查看它是否工作(即rm -r ~/.cache/matplotlib)。
就我而言，它解决了这个问题：
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

如果您在安装HumorSans字体后仍然看到错误，我建议运行：
import matplotlib
matplotlib.font_manager._rebuild()它将重新生成字体缓存。

对于matplotlib==3.4.3，我不得不这样做：
import shutil
import matplotlib
shutil.rmtree(matplotlib.get_cachedir())页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
