kivy 无法导入名称“调色板”
运行 kivy 代码时出现奇怪的导入错误。我怎样才能解决这个问题？
文件：
from kivy.uix.screenmanager import Screen
from kivymd.app import MDApp
from kivymd.uix.button import MDRectangleFlatButton
class MainApp(MDApp):
def build(self):
self.theme_cls.primary_palette = "Green" # "Purple", "Red"
screen = Screen()
screen.add_widget(
MDRectangleFlatButton(
text="Hello, World",
pos_hint={"center_x": 0.5, "center_y": 0.5},
)
)
return screen
MainApp().run()
错误：
from kivymd.color_definitions import palette, hue, text_colors
ImportError: cannot import name 'palette'

如果您使用的是 python 3.8 版本，则会收到此错误。降级到 3.7 版本会有所帮助 -

我在我的系统上试了一下，效果很好，你使用的是最新版本的KivyMDfromGitHub吗？此外，为了解决错误，请按照以下说明进行操作转到kivymd文件夹打开color_definitions.py文件确保三个列表 - palette、hue、text_colors存在。如果没有，请将以下内容粘贴到color_definitions.py文件中并保存palette = [ "Red", "Pink", "Purple", "DeepPurple", "Indigo", "Blue", "LightBlue", "Cyan", "Teal", "Green", "LightGreen", "Lime", "Yellow", "Amber", "Orange", "DeepOrange", "Brown", "Gray", "BlueGray",]hue = [ "50", "100", "200", "300", "400", "500", "600", "700", "800", "900", "A100", "A200", "A400", "A700",]text_colors = { "Red": { "50": "000000", "100": "000000", "200": "000000", "300": "000000", "400":
