Question

我尝试使用Kivy的Buildozer VM通过Buildozer制作apk，但出现错误：

我已经升级了appdirs，colorama，jinja2、6，sh等。

我认为主要问题是Buildozer使用的是python版本2.7。如何手动将其更改为python 3+版本？

Answer 1

我对buildozer不熟悉，但是在Project description中，我看到了：

使用目标Python 3安装Buildozer（默认）：

...

使用目标Python 2安装Buildozer
遵循与Python 3相同的安装和buildozer初始化
确保以下行在buildozer.spec文件中。
# Changes python3 to python2
requirements = python2,kivy

因此，尝试尝试的一件事是检查buildozer.spec文件中是否有引述的摘录，如果有，请还原它。
