python - 文本输入的 Kivy 错误

Question

我正在尝试在我的电脑上运行此代码，我尝试了各种方法，但总是遇到相同的错误，我不知道该怎么办...

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，但我无法构建到android

我遇到了同样的错误，但安装 xclip & xsel 为我解决了这个问题。
