Question

我在kivy有这个代码，控制台在'源'行上说错了...

为什么？我不明白，因为在我的学校电脑和我的Android手机上，它的效果非常好！

<Jeu>: #BoxLayout
canvas:
    Rectangle:
        source: 'fond.png'
        pos: self.pos
        size: self.size

你能帮助我吗？

我认为错误发生在您的.kv文件中。你有这个：

canvas:
    Rectangle:
        source: "fond.png"
        pos: self.pos
        size: self.size

你应该试试这个：

canvas:
    Rectangle:
        Image:
            source: "fond.png"
            pos: self.pos
            size: self.size
