首先，当我们使用canvas.itemconfigure时，我们需要设置要更改其选项的对象的标签或Id，然后我们选择要更改的选项。在这种情况下，我认为没有必要使用 itemconfigure，因为您已经创建了要创建的图像。此外，canvas.create_image 没有名为 fill 的选项。
我已经通过两次更改解决了问题
先做Global img2
global img2
img2 = ImageTk.PhotoImage(img)
第二次更改这些行
self.image_on_canvas = canvas.create_image(0, 0, anchor="nw", image=img2)
canvas.config(self.image_on_canvas)
我了解到，当使用 image_on_canvas = canvas.create_image (0, 0, anchor = "nw", image = img2) 时，它 returns 一个用于识别的 int具体的 canvas 元素（它的 id）。对于他们，只需将行更改为：canvas.create_image (0, 0, anchor = "nw", image = img2)
