我正在努力用buildozer和kivy构建应用程序。 我的应用程序有三个要求：请求，kivy和日期时间。 直接构建应用程序时，我收到以下错误：
# Install distribute

Usage:

pip install [options] -r <requirements file> [package-index-options] ...
pip install [options] [-e] <vcs project url> ...
pip install [options] [-e] <local project path> ...
pip install [options] <archive url/path> ...
no such option: --download-cache
# Command failed: pip install --download-cache=/home/USER/.buildozer/cache --target=/home/USER/python/ZugGit/ZugAppFahrt/.buildozer/applibs requests
#
# Buildozer failed to execute the last command
# The error might be hidden in the log above this error
# Please read the full log, and search for it before
# raising an issue with buildozer itself.
# In case of a bug report, please add a full log with log_level = 2
我已经阅读了很多内容，发现问题出现在--download-cache命令中。
所以我从buildozer文件夹中的 init .py文件中删除了这部分，但现在我收到以下错误：
# Cwd /home/USER/python/ZugGit/ZugAppFahrt/.buildozer
Directory '/home/USER/python/ZugGit/ZugAppFahrt/.buildozer/applibs' is not installable. File 'setup.py' not found.
# Command failed: pip install --target=/home/USER/.buildozer/cach/home/USER/python/ZugGit/ZugAppFahrt/.buildozer/applibs
我对此完全陌生，无法弄清问题是什么。我可以做什么，我的应用程序正确构建。如果我构建应用程序而不仅仅是以kivy为要求，那么应用程序已经构建，但由于缺少请求而在开始时崩溃。
非常感谢任何帮助。
编辑：问题是我通过删除“--download-cache”部分引入了一个空格。
但是我遇到了一个新问题。现在我收到以下错误：
BUILD FAILED

有趣的是，我在buildozer中引入了一个新的错误，因为我也无法在没有要求的情况下构建应用程序。
