【问题描述】：

我正在尝试从 Linux 中的推土机创建一个 apk 文件，但每次我收到此错误时都找不到 cython。虽然我尝试安装它，但我找到了整个互联网但没有得到答案。请帮助我。我是初学者 代码：

【参考方案1】：

这是因为 buildozer 搜索 cython，但实际的命令是 cython3。要解决这个问题，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

在会弹出的编辑器中写

cython3 $@

这会将所有参数从 cython 传递给 cython3。保存文件并在终端写入

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

【参考方案2】：

更安全、更简单的方法（这样你就可以避免转义参数等问题）是创建一个软链接

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