实战打包PySide2

打包示例源码下载:

请看文章末尾
 

版本信息:

PySide2==5.15.2

Nuitka==0.6.19.1

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。因为PySide2和PyQt5两个库所使用的API绝大部分是一样的。所以针对这个记事本应用,我们只需要把导入地方的PyQt5改成PySide2即可

 项目目录如下:

hello.py修改代码如下(就是把导入的PyQt5改成了PySide2):

import sys
from PySide2.QtGui import QIcon
from PySide2.QtCore import QMimeData
from PySide2.QtWidgets import QApplication, QMainWindow, QTextEdit, QAction, QFileDialog, QMessageBox, \\

    demo.show()
    sys.exit(app.exec_())

运行截图如下:

打包分析如下:

  1. 既然有PySide2,那么我们肯定要用到--enable-plugin=pyside2来启用插件。 
  2. 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=pyside2 --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=pyside2 --include-data-dir=./images=./images hello.py

注:Nuitka目前并不是完全支持打包PySide2,部分程序可能会出现问题,详情可以去官方文档了解。
