python - 在 Mac OS Mojave 上使用 py2app 部署 Kivy 应用程序

Question

我一直试图在 Mac OS 上分发我简单的 Kivy 应用程序，但我仍然失败了。我的环境：macOS Mojave 版本。10.14.6 与 Homebrew 一起安装的 Python 3.7.3 以及 pyenv 可以维护几个 python 版本 Kivy 1.11.1 以及一系列 Homebrew 库，例如 pig-config sdl2 sdl2_image、Gstreamer 等。

该应用程序在本地环境中运行时运行良好，但是我无法创建用于分发的版本。

我在 pyinstaller 上花了一些时间，但它不断给我丢失路径和库的错误，所以我开始寻找另一个工具，我发现了 py2app。

我可以使用以下命令轻松地以别名模式运行应用程序：

    python setup.py py2app -A

接着

    ./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.
