打包个apk,为什么出现了Cython (cython) not found, please install it.错误,安装了Cython也不行!

问题遇到的现象和发生背景

我想在python打包个apk程序,结果。

问题相关代码,请勿粘贴截图

buildozer android debug

运行结果及报错内容
# Check configuration tokens
# Ensure build layout
# Check configuration tokens
# Read available permissions from api-versions.xml
# Preparing build
# Check requirements for android
# Search for Git (git)
#  -> found at /usr/bin/git
# Search for Cython (cython)
# Cython (cython) not found, please install it.

# Cython (cython) not found, please install it.

我的解答思路和尝试过的方法

pip install cython不行,还是这个错误。
Cython和Kivy版本:

Cython  0.29.32
Kivy       2.1.0
我想要达到的结果

成功的打包
