为什么我在 python 中出现导入错误，当我安装了 pip 我的应用程序所需的每个模块时

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()

After running this I am getting the result this:

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

Why am I getting this? When ever I run it I get this only. And nothing else.

Please tell and help me with my code!

Answer 1

Use GridLayout, with a capital L

from kivy.uix.gridlayout import GridLayout

Answer 2

You can see in the error message that it cannot import "Gridlayout" because the actual name is "GridLayout". I think this will fix your issue.

Use this:

from kivy.uix.gridlayout import GridLayout
