嘗試在 pycharm 中運行簡單的 kivy 程序時出錯

Question

我試圖運行這段代碼：

kivy.require('1.11.1')
from kivy.app import App
from kivy.uix.label import Label

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

if __name__ == '__main__':
    MyApp().run()

但我收到此錯誤消息：

[INFO   ] [deps        ] Successfully imported "kivy_deps.glew" 0.2.0

我正在使用 pycharm 並已安裝：Kivy、kivy-deps.glew、kivy-deps.gstreamer、kivy-deps.sdl2、Z9CC577E6C3230F1D54EEA8690A。

我正在使用 python 3.7

已經收到此錯誤，它在我更新 pycharm 並僅為 Kivy 創建新環境后才起作用。

您還需要導入 kivy 才能使用 require。

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

kivy.require('1.11.1')


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


if __name__ == '__main__':
    MyApp().run()
