buildozer失败，使用纯python库（品脱）

Question

我正在尝试创建一个kivy应用程序，并且我想包含pint库，因此我在我的buildozer.spec文件中添加了pint ：

requirements = kivy, hostpython2, pint

但是，运行时

buildozer android_new debug deploy

我收到一个错误（请参阅下面的日志）。 如果我从需求中删除pint ，一切都会很好，但是我不明白为什么这会导致错误，因为pint是一个没有依赖性的纯python模块。

我不了解日志文件中的错误，但是我确实看到ImportError: cannot import name HTTPSHandler因此我也尝试在要求中包括HTTPSHandler，但这并不能解决任何问题。

似乎该错误是由使用conda环境引起的。 当我使用默认的python安装（在Mac OSX上）时，问题已解决。
