如果您使用的是 python 3.8 版本，則會(huì)收到此錯(cuò)誤。降級(jí)到 3.7 版本會(huì)有所幫助

我在我的系統(tǒng)上試了一下，效果很好，你使用的是最新版本的KivyMDfromGitHub嗎？
此外，為了解決錯(cuò)誤，請(qǐng)按照以下說(shuō)明進(jìn)行操作
轉(zhuǎn)到
kivymd文件夾打開(kāi)
color_definitions.py文件確保三個(gè)列表 -
palette、hue、text_colors存在。
如果沒(méi)有，請(qǐng)將以下內(nèi)容粘貼到color_definitions.py文件中并保存
