当我使用pytube之类的python模块或任何其他模块时，应用程序总是失败

Question

所以我用python pytube和kivy制作了一个youtube视频下载程序，像往常一样，我尝试制作一个apk，但它不起作用，我尝试将pytube添加到我的需求中：在buildozer.spec中，但它一直失败。有人能告诉我这个问题吗？因为我尝试了很多次导入python模块，但总是失败 这是我的代码：

from kivy.lang import Builder
from kivymd.app import MDApp
from kivymd.uix.filemanager import MDFileManager
from kivymd.toast import toast
from kivy.core.window import Window
import pytube


class Main(MDApp):
    def build(self):
        Window.size = (Window.width,Window.height)
        kv = Builder.load_file("Design.kv")
        self.theme_cls.theme_style = "Dark"
        self.theme_cls.primary_palette = "Red"
        return kv

    def VidDown(self):
        try:
            yt = pytube.YouTube(self.root.ids.Link.text)
            self.root.ids.thumbnail.color = 1,1,1,1
            self.root.ids.thumbnail.source = yt.thumbnail_url
            if self.root.ids.low.color == [.21176470535294, .098039627451, 1, 1]:
                print("low")
                yt.streams.first().download()
            elif self.root.ids.mid.color == [.21176470535294, .098039627451, 1, 1]:
                print("mid")
                yt.streams.filter(progressive = True, file_extension = "mp4").get_lowest_resolution().download()
            elif self.root.ids.high.color == [.21176470535294, .098039627451, 1, 1]:
                print("high")
                yt.streams.filter(progressive = True, file_extension = "mp4").get_highest_resolution().download()
            elif self.root.ids.audio.color == [.21176470535294, .098039627451, 1, 1]:
                print("audio")
                downloaded_file = yt.streams.filter(only_audio = True, subtype='webm', abr='160kbps').first().download()
        except:
            print("Error")
    def reset(self):
        self.root.ids.low.color = [255/255,0/255,40/255,1]
        self.root.ids.mid.color = [255/255,0/255,40/255,1]
        self.root.ids.high.color = [255/255,0/255,40/255,1]
        self.root.ids.audio.color = [255/255,0/255,40/255,1]
