python - kivy 进口出了什么问题？

Question

尝试运行 kivy 应用程序时出现错误:

这是我的代码:

import kivy

from kivy.app import App
from kivy.uix.label import Label

    def build(self):
        return Label(text='Hello world')

Answer 1

您的错误是由于以下原因造成的:

pil - ModuleNotFoundError: No module named 'PIL'

您使用的是什么python --version？

尝试安装pip install Pillow

注意:PIL 已贬值，Pillow 较新。
