尝试在pycharm中运行简单的kivy程序时出错

问题描述

我试图运行以下代码：

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()

但是我收到此错误消息：

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

我正在使用pycharm并已安装：Kivy，kivy-deps.glew，kivy-deps.gstreamer，kivy-deps.sdl2，pygame和枕头。

我正在使用python 3.7

解决方法

已经出现此错误，在我更新pycharm并仅为Kivy创建了新环境后，该错误起作用了。

您还需要导入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()
