為什么我在 python 中出現導入錯誤，當我安裝了 pip 我的應用程序所需的每個模塊時

Question

import kivy
from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.gridlayout import Gridlayout
from kivy.uix.textinput import TextInput


class MyGrid(GridLayout):
    def __init__(self, **kwargs):
        super(MyGrid, self).__init__(**kwargs)
        self.cols = 2
        self.add_widget(Label(text="Name: "))
        self.name = TextInput(multiline=False)
        self.add_widget(self.name)
        



class MyApp(App):
    def build(self):
        return MyGrid()

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

運行此之后，我得到以下結果：

 ImportError: cannot import name 'Gridlayout' from 'kivy.uix.gridlayout' (C:\Users\skkar\AppData\Local\Programs\Python\Python39\lib\site-packages\kivy\uix\gridlayout.py)

為什么我會得到這個？ 當我運行它時，我只會得到這個。 沒有別的了。

請告訴我的代碼並幫助我！

Answer 1

使用 GridLayout，大寫 L

from kivy.uix.gridlayout import GridLayout

Answer 2

您可以在錯誤消息中看到它無法導入“Gridlayout”，因為實際名稱是“GridLayout”。 我認為這將解決您的問題。

用這個：

from kivy.uix.gridlayout import GridLayout
