Kivy 在 Cygwin 中找不到字体

Question

我在Cygwin.中使用Kivy

每 瓦西尔科夫，马克。 Kivy 蓝图。伯明翰：Packt Publishing，2015。第 17 页，我想在以下代码中使用 Roboto 字体：

# File: main.py

from kivy.app import App
from kivy.core.text import LabelBase

LabelBase.register(name='Roboto',
        fn_regular='Roboto-Thin.ttf',
        fn_bold='Roboto-Medium.ttf')

class ClockApp(App):
    pass

if __name__ == '__main__':
    ClockApp().run()

然而，即使Cygwin 知道Roboto 字体安装在/usr/share/fonts/, 中，即：

$ fc-list | grep -i robot
/usr/share/fonts/roboto/Roboto-Regular.ttf: Roboto:style=Regular
/usr/share/fonts/roboto/Roboto-LightItalic.ttf: Roboto,Roboto Light:style=Light Italic,Italic
/usr/share/fonts/roboto/Roboto-Bold.ttf: Roboto:style=Bold
/usr/share/fonts/roboto/Roboto-MediumItalic.ttf: Roboto,Roboto Medium:style=Medium Italic,Italic
/usr/share/fonts/roboto/Roboto-ThinItalic.ttf: Roboto,Roboto Thin:style=Thin Italic,Italic
/usr/share/fonts/roboto/RobotoCondensed-Italic.ttf: Roboto Condensed:style=Italic
/usr/share/fonts/roboto/Roboto-Italic.ttf: Roboto:style=Italic
/usr/share/fonts/roboto/Roboto-Black.ttf: Roboto,Roboto Black:style=Black,Regular
/usr/share/fonts/roboto/RobotoCondensed-LightItalic.ttf: Roboto Condensed,Roboto Condensed Light:style=Light Italic,Italic
/usr/share/fonts/roboto/Roboto-Light.ttf: Roboto,Roboto Light:style=Light,Regular
/usr/share/fonts/roboto/RobotoCondensed-Regular.ttf: Roboto Condensed:style=Regular
/usr/share/fonts/roboto/Roboto-BoldItalic.ttf: Roboto:style=Bold Italic
/usr/share/fonts/roboto/RobotoCondensed-BoldItalic.ttf: Roboto Condensed:style=Bold Italic
/usr/share/fonts/roboto/RobotoCondensed-Light.ttf: Roboto Condensed,Roboto Condensed Light:style=Light,Regular
/usr/share/fonts/roboto/RobotoCondensed-Bold.ttf: Roboto Condensed:style=Bold
/usr/share/fonts/roboto/Roboto-Medium.ttf: Roboto,Roboto Medium:style=Medium,Regular
/usr/share/fonts/roboto/Roboto-Thin.ttf: Roboto,Roboto Thin:style=Thin,Regular
/usr/share/fonts/roboto/Roboto-BlackItalic.ttf: Roboto,Roboto Black:style=Black Italic,Italic

当我运行上面的 Python 代码时，我得到：

$ python main.py
[INFO   ] [Logger      ] Record log in /home/Administrator/.kivy/logs/kivy_16-10-09_18.txt

     raise IOError('File {0}s not found'.format(font_type))
 IOError: File Roboto-Thin.ttfs not found

我应该怎么做才能让Kivy 使用Roboto 字体？

Answer 1

您必须在LabelBase.register() 中提供字体的路径。你的目录中有那些字体文件吗？
