在Mac OS Mojave上使用py2app进行Kivy应用程序部署

如何解决在Mac OS Mojave上使用py2app进行Kivy应用程序部署

我一直试图在Mac OS上篡改我的简单Kivy应用程序，但仍然失败。 我的环境： macOS Mojave版本10.14.6 与Homebrew和pyenv一起安装的Python 3.7.3，可维护多个python版本 已安装Kivy 1.11.1以及一堆Homebrew库，例如pig-config sdl2 sdl2_image，Gstreamer等。

从本地环境运行时，该应用程序运行正常，但是我无法创建要分发的版本。

我花了一些时间在pyinstaller上，但是它不断给我带来缺少路径和库的错误，因此我开始寻找另一种工具，然后发现了py2app。

我可以使用以下方式轻松地以别名模式运行该应用程序：

    python setup.py py2app -A

然后

    ./dist/app.app/Contents/MacOS/app

但是当我使用普通模式创建部署版本时：

    python setup.py py2app

然后启动应用程序

    ./dist/app.app/Contents/MacOS/app

我收到以下错误：

I did a google search on 
**SystemError: <method 'load_module' of 'zipimport.zipimporter' objects> returned NULL without setting an error**
but I didn't get any responses related to this issue.

I am not sure what I should do to troubleshoot.
Any insights would be appreciated.
