打包环境：
Windows10 64位
笔者就拿在《快速掌握PyQt5》第二十三章 主窗口QMainWindow中写的记事本应用来打包。

运行截图如下：
打包分析如下：
- 既然有PyQt5，那么我们肯定要用到--enable-plugin=pyqt5来启用插件。
- 程序用到资源文件，而资源文件全部都放在images文件夹下，也就是说我们可以用--include-data-dir命令来打包images文件夹。
打包命令如下：
nuitka --standalone --enable-plugin=pyqt5 --include-data-dir=./images=./images hello.py打包结束后，运行hello.exe文件，显示如下：
确认运行没有任何报错之后，加上--windows-disable-console去掉黑框再次打包。
nuitka --standalone --windows-disable-console --enable-plugin=pyqt5 --include-data-dir=./images=./images hello.py
