android - 如何将 SQLAlchemy 与 buildozer 一起使用？

Question

最近buildozer编译了一个简单的"hello world"程序。

但我想在 ma​​in.py 文件中使用 SQLAlchemy。

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()

还有一个 myapp.kv 文件，其中包含:

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

我更改了 buildozer.spec 文件中的必要部分:

# (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 

但它给出了一个错误。

我想知道的是，我应该像下面这样更改规范文件的一部分，还是应该做不同的事情？

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

提前致谢。

配方名称是sqlalchemy，而不是SQLAlchemy。

我会考虑添加一些关于案例的检查或警告，我以前没有想过这类问题。
