Ttkbootstrap 仪表小部件文档示例不起作用

Question

我尝试了 ttkbootstrap 的仪表小部件的示例，但它似乎不起作用。我复制并粘贴了确切的代码，并收到此错误“AttributeError：模块“PIL.Image”没有属性“CUBIC”。您是指：“BICUBIC”吗？'

这是代码

import ttkbootstrap as ttk
from ttkbootstrap.constants import *

app = ttk.Window()

meter = ttk.Meter(
    metersize=180,
    padding=5,
    amountused=25,
    metertype="semi",
    subtext="miles per hour",
    interactive=True,
)
meter.pack()

# update the amount used directly
meter.configure(amountused = 50)

# update the amount used with another widget
entry = ttk.Entry(textvariable=meter.amountusedvar)
entry.pack(fill=X)

# increment the amount by 10 steps
meter.step(10)

# decrement the amount by 15 steps
meter.step(-15)

# update the subtext
meter.configure(subtext="loading...")

app.mainloop()
`

AttributeError: module 'PIL.Image' has no attribute 'CUBIC'. Did you mean: 'BICUBIC'?

Answer 1

由于属性

Image.CUBIC

已弃用（由

Image.BICUBIC

取代）并在

Pillow

v10.0.0 中删除。安装旧版本 (v9.5.0) 的

Pillow

模块或在导入

ttkbootstrap

模块之前显式创建属性：

from PIL import Image
Image.CUBIC = Image.BICUBIC
import ttkbootstrap as ttk
...

Answer 2

从 PIL 导入图像 图像.CUBIC = 图像.BICUBIC

它正在工作！ 谢谢
