SQLAlchemyをbuildozerで使用するには？

Question

最近、buildozerは簡単な"hello world"プログラムをコンパイルしました。

しかし、main.pyファイルでSQLAlchemyを使用したいと思います。

ファイルが含まれています

# (list) Application requirements 
# comma seperated e.g. requirements = sqlite3,kivy 
requirements = python3crystax,SQLAlchemy,kivy 

# change the major version of python used by the app 
osx.python_version = 3 

# Kivy version to use 
osx.kivy_version = 1.10.0 

# (str) Android NDK version to use 
#android.ndk = 9c 
android.ndk = 10.3.2 

# (str) Android NDK directory (if empty, it will be automatically downloaded.) 
#android.ndk_path = 
android.ndk_path = /opt/crystax-ndk-10.3.2 

：

GridLayout: 
    cols: 2 
    Label: 
     id: etkt 
     text: 'Etiket' 
    Button: 
     text: 'Tıkla' 
     on_press: app.olustur() 

私はbuildozer.specファイルにnecessarryパーツを変更：

# -*- coding: utf-8 -*- 
import kivy 
kivy.require('1.10.0') 
from kivy.app import App 
from kivy.uix.button import Button 
from sqlalchemy import create_engine 
from kivy.uix.label import Label 

class MyApp(App): 

    def build(self): 
     pass 

    def olustur(self): 
     engine = create_engine('sqlite:///database.db', echo = True) 
     cur = engine.connect() 
     self.root.ids['etkt'].text = 'Bağlantı Başarılı!' 

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

にも含まれていmyapp.kvファイルがあります

しかし、エラーが発生します。

私が学びたいことは、以下のようなスペックファイルの部分も変更する必要がありますか、別のことをする必要がありますか？

# (str) Custom source folders for requirements 
# Sets custom source for any requirements with recipes 
# requirements.source.kivy = ../../kivy 
    requirements.source.SQLAlchemy = .../../SQLAlchemy 

ありがとうございます。

レシピ名がsqlalchemy、ないSQLAlchemyです。

私は、この種の問題について以前は考えていませんでした。
