Kivy Buildozer“ImportError：没有名为 docopt 的模块”

Question

我完成了 Kivy 应用程序的开发，现在我想将其打包以在 Mac OS X 上运行。我正在关注 Kivy 文档中的 these instructions。不幸的是，我遇到了一些麻烦：

环境

• Mac OS X 10.10.5
• Kivy 1.9.1 @ /Applications/kivy.app（Python3 版本 基维）
• 通过 Homebrew 的 Python 3.5.1

安装 Buildozer

sudo pip3.5 install buildozer

为 Mac OS X 构建 Kivy 应用

cd /my/app
buildozer init
buildozer osx debug

结果

# Check configuration tokens
# Ensure build layout
# Create directory .buildozer
# Create directory bin
# Create directory /my/app/.buildozer/applibs
# Create directory .buildozer/osx/platform
# Create directory .buildozer/osx/app
# Check configuration tokens
# Preparing build
# Check requirements for osx
# Check if kivy-sdk-packager exists
# kivy-sdk-packager does not exist, clone it

据我所知，我的 Kivy 应用不需要 docopt，所以我不确定 Buildozer 为何抱怨它。这个问题的解决方法是什么？

Answer 1

你可以：

1. 删除该行

   从文档导入文档

2. 只需将 docopt.py 放在你的 package_app.py 旁边

Answer 2

我找到了解决问题的方法。所以，package_app.py 是用 Python2 编写的。因此，它需要在系统 Python2 中安装这些模块：

pip2 install docopt sh

现在 Buildozer 很高兴，我也很高兴。

顺便说一句，为了减小我的应用程序的大小，我在打包前剪掉了脂肪。具体来说，我从myapp/.buildozer/osx/platform/kivy-sdk-packager-master/osx/Kivy.app/Contents/Frameworks 中删除了gstreamer。这消除了约 190 MB 的脂肪。百胜:)
