Answer 1

这是因为buildozer搜索cython，但实际命令是cython3。要解决此问题，您必须创建一个 cython 命令，将所有参数传递给 cython3。

在终端中写入

cd /bin/ && sudo gedit cython

在弹出的编辑器中写入

cython3 $@

这会将所有参数从 cython 传递到 cython3。保存文件并在终端中写入

sudo chmod 755 cython

使其可执行。要测试它，只需编写

cython

它应该具有与

相同的输出

cython3

Answer 2

更安全、更简单的方法（这样可以避免转义参数等问题），是创建软链接

sudo ln -s /usr/bin/cython3 /usr/local/bin/cython    

Answer 3

如果您无法在终端中安装 cython，另一种解决方案是创建一个虚拟环境并在那里下载 cython。激活它后，buildozer 就会找到它。

Answer 4

对我有用的是通过 apt 和

apt install cython3

安装它，之后就完美了。

如果该命令不起作用，只需在终端中输入

cython

，ubuntu 将帮助您安装它。
