使用纯python库(pint)，buildozer失败

Question

我正在尝试创建一个kivy应用程序，并且我希望包含pint库，所以我将pint添加到了我的buildozer.spec文件中：

requirements = kivy, hostpython2, pint

但是，当运行时

buildozer android_new debug deploy

我收到一个错误(见下面的日志)。如果我将pint从需求中删除，一切都会正常工作，但我不明白这为什么会导致错误，因为pint是一个纯python模块，没有依赖关系。

我不明白日志文件中的错误，但我确实看到了ImportError: cannot import name HTTPSHandler，所以我也尝试将HTTPSHandler包括在需求中，但这并没有修复任何问题。

该错误似乎是由使用conda环境引起的。当我使用默认的python安装(在我的Mac上)时，问题得到了解决。
