Buildozer Android 打包错误 - sh.ErrorReturnCode_2: <exception str() failed>

Buildozer Android packaging error - sh.ErrorReturnCode_2: <exception str() failed>

我尝试构建 Kivy 应用程序的 APK。我正在全新安装 VirtualBox,这是 Ubuntu 的虚拟机。 我尝试构建的应用程序(作为初学者)是 Kivy 教程的标准应用程序,因此这不太可能是错误的原因。

我已经找到问题所在(尽管我不明白为什么会出现这个问题),请参阅下文。我想通过问答来分享这个。

#    List as sections
#
#    You can define all the "list" as [section:key].
#    Each line will be considered as a option to the list.
#    Let's take [app] / source.exclude_patterns.
#    Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
#    This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#


#    -----------------------------------------------------------------------------
#    Profiles
#
#    You can extend section / key with a profile
#    For example, you want to deploy a demo version of your application without
#    HD content. You could first change the title to add "(demo)" in the name
#    and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
#    Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug

Python /media/sf_HelloWorld/main.py的代码(从Kivy教程中复制):

from kivy.app import App

from kivy.uix.scatter import Scatter
from kivy.uix.label import Label
from kivy.uix.floatlayout import FloatLayout

class TutorialApp(App):
    def build(self):
        f = FloatLayout()
        s = Scatter()
        l = Label(text="Hello!",
                  font_size=150)

        f.add_widget(s)
        s.add_widget(l)
        return f

if __name__ == "__main__":
    TutorialApp().run()

我发现它不起作用,因为我使用了 VirtualBox 和 Windows 主机之间的共享文件夹,/media

当我将文件复制到另一个文件夹时,构建成功!
