如何將SQLAlchemy與buildozer一起使用？

最近buildozer編譯了一個簡單的「hello world」程序。如何將SQLAlchemy與buildozer一起使用？

但我想在main.py文件中使用SQLAlchemy。

該文件包含：

# -*- 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()

而且還有一個myapp.kv文件，其中包含：

# (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()

我buildozer.spec文件改變了necessarry零件

但它給出了一個錯誤。

我想學的是，我應該改變下面的規格文件的一部分，或者我應該做一個不同的事情？

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

在此先感謝。

配方名是sqlalchemy，不SQLAlchemy。

我會看看添加某種檢查或警告的情況下，我沒有想過這種類型的問題。

我想你是對的。順便說一下最近一個android apk由Python 2.7創建。在.spec文件中，需求被寫入requirements = sqlite3，sqlalchemy，kivy。我會再次嘗試使用Python3。 –

我用Python2和Python3創建了一個簡單的「hello world」程序。但是這個sqlalchemy例子還沒有被Python3編譯。我添加了第一個例子的要求。 ndk版本相同，kivy版本相同。但它給出了一個錯誤。奇怪。也許我做了一些我還沒找到的錯誤。 –

sqlalchemy配方可能尚未經過python3測試。這就是說，你是否遵循[說明]（http://python-for-android.readthedocs.io/en/latest/buildoptions/#python3），特別是使用CrystaX NDK？ – inclement
