首先，我把我的自定义字体STKAITI.TTF到/usr/local/share/fonts，然后重建字体缓存fc-cache -fv。
但我仍然不能在matplotlib中使用它。
In [13]: matplotlib.font_manager.findSystemFonts(fontpaths=None, fontext='ttf')
Out[13]:
['/usr/share/fonts/truetype/dejavu/DejaVuSerif.ttf',
'/usr/local/share/fonts/STKAITI.TTF', # font is here
'/usr/share/fonts/truetype/dejavu/DejaVuSerif-Bold.ttf',
'/usr/local/share/fonts/NotoSansSC-Regular.otf',
'/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf',
'/usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf',
'/usr/share/fonts/truetype/dejavu/DejaVuSans-Bold.ttf',
'/usr/share/fonts/truetype/dejavu/DejaVuSansMono-Bold.ttf']然后：
import matplotlib.pyplot as plt
In [6]: plt.rcParams["font.sans-serif"] ## this is definded in my '~/.config/matplotlib/matplotlibrc'
Out[6]:

1条答案
按热度按时间rpppsulh1#
所以我在这方面遇到了一些麻烦，直到我发现了对我来说特别的问题。我用wget下载的.ttf字体文件基本上是空壳。
对我来说，下载一个zip文件，然后检查文件是否真的下载了，然后我直接将文件复制到第一个目录中
我还删除了字体缓存：
我重新运行了脚本，列表的大小增加了，我可以在matplotlib中使用字体了。我想这对我很有帮助的原因是因为它让我看到了matplotlib从3个不同的位置获取字体的所有位置。
