文本输入的 Kivy 错误

Question

我正在尝试运行我的电脑中的这段代码，我尝试了所有方法，但总是遇到同样的错误，我不知道该怎么做...

import kivy
kivy.require('1.0.7') 
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.codeinput import CodeInput
from kivy.uix.button import Button
from kivy.uix.label import Label
from kivy.uix.textinput import TextInput
from kivy.core.window import Window
from kivy.uix.accordion import Accordion, AccordionItem

Window.clearcolor = (1, 1, 1, 1)


class Myapp(App):

    def build(self):

        self.layout = BoxLayout(padding=50,orientation="vertical",spacing=30)
        Labe_Prin = Label(text="Bienvenido al login",font_name="data/fonts/Union_soap.ttf",color=(0,0,0,0.5),font_size=50)
        Label1 = Label(text="Ingrese Usuario: ",color=(0,0,0,1),font_size=(50*0.75),bold=True,italic=False,font_name="data/fonts/English_.ttf")
        Entrada1 = TextInput(multiline = False,size_hint=(1,.3),bold=True,font_size=12.3,foreground_color=(.5,.1,.3,1),text="Usuraio",use_bubble=True) #focus=True,use_handles=True
        Label2 = Label(text="Ingrese Contrasenia: ",color=(0,0,0,1),font_size=(50*0.75),bold=True,italic=False,font_name="data/fonts/English_.ttf")
        Entrada2 = CodeInput(multiline = False,size_hint=(1,.3),italic=True,font_size=12.3,foreground_color=(.5,.1,.3,1),text="Contrasenia",use_buble=True) #Contrasenia

        def press(self):
            print Entrada1.text
            print Entrada2.text

        Boton1 = Button(size_hint=(1, .4), text='Login',on_release=press)


        self.layout.add_widget(Labe_Prin)
        self.layout.add_widget(Label1)
        self.layout.add_widget(Entrada1)
        self.layout.add_widget(Label2)
        self.layout.add_widget(Entrada2)
        self.layout.add_widget(Boton1)

        return self.layout

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

我有这个错误...

我可以执行代码，但无法构建到 android

Answer 1

我遇到了同样的错误，但安装 xclip 和 xsel 为我解决了这个问题。

Answer 2

sudo apt-get install xclip xsel

Answer 3

我遇到了同样的错误。

$ sudo apt-get install xclip xsel

但这并没有帮助，因为某些基于 Ubuntu 的 OS（例如 Xubuntu 20.04.1 focal）没有可用的所需软件包。在这种情况下（当您遇到“E: 无法定位包 xclip”时），您需要使用此包添加存储库：

$ sudo add-apt-repository universe
$ sudo add-apt-repository multiverse
$ sudo apt update
$ sudo apt-get install xclip xsel

P.S。也许你只需要 universe 或 multiverse repository ，但我安装了它们。

P.S.S.这只是问题的详细答案。因为我花了大约 30 分钟才找到“无法定位包 *”错误的解决方案。
