缺少字体
将此

[Python] 纯文本查看 复制代码

?

1	FONT_PATH = 'AlibabaPuHuiTi-3/AlibabaPuHuiTi-3-55-Regular/AlibabaPuHuiTi-3-55-Regular.ttf'

改为

[Python] 纯文本查看 复制代码

?

1	FONT_PATH = 'Alibaba-PuHuiTi-Regular.ttf'

字体下载地址https://fontmeme.com/fonts/alibaba-puhuiti-font/
字体文件放py文件夹

都可以,放dist文件那么FONT_PATH = 'dist/Alibaba-PuHuiTi-Regular.ttf'

FONT_PATH = 'Alibaba-PuHuiTi-Regular.ttf'
是指的
C:\Users\Administrator\AppData\Local\Programs\Python\Python313
这个文件夹吗？纯小白，打扰大佬了
