1、复制字体到系统目录:sudo cp winfonts/simhei.ttf /usr/share/fonts/TTF/
2、复制字体到matplotlib的字体目录中：sudo cp winfonts/simhei.ttf /usr/lib/python3.10/site-packages/matplotlib/mpl-data/fonts/ttf/
3、修改配置文件：sudo vim /usr/lib/python3.10/site-packages/matplotlib/mpl-data/matplotlibrc,将simhei信息添加，具体就是：
1 font.family: simhei, sans-serif 2 #font.style: normal 3 #font.variant: normal 4 #font.weight: normal 5 #font.stretch: normal 6 font.size: 14.0 7 8 font.serif: simhei, DejaVu Serif, Bitstream Vera Serif, Computer Modern Roman, New Century Schoolbook, Century Schoolbook L, Utopia, ITC Bookman, Bookman, Nimbus Roman No9 L, Times New Roman, Times, Palatino, Charter, serif 9 font.sans-serif: simhei, DejaVu Sans, Bitstream Vera Sans, Computer Modern Sans Serif, Lucida Grande, Verdana, Geneva, Lucid, Arial, Helvetica, Avant Garde, sans-serif
分别在第1、8、9行添加字体信息
4、python WORKM/pythonCode/chapter15/mplSquares.py结果：
