1.简介

一个使用python PYQT5制作的关于pyinstaller打包工具,代替传统的cmd黑窗口模式打包页面,实现更快捷方便的python打包体验。资源已打包,大家可自行下载。

相关功能:

  • 识别是否安装了pyinstaller,如果没有的话,打开在左上角会提示,并在右上角增加“安装”按钮。
  • 打包过程设置为隐式。并且加入“显示处理”选项。
  • 支持一键拖拽文件以及自动选择文件。
  • 支持导出到桌面以及设置打包好的软件图标。

pyinstaller 相关参数:

-F    制作独立的可执行程序

-D    制作出的档案存放在同一个文件夹下(默认值)

-K    包含TCL/TK(对于使用了TK的,最好加上这个选项,否则在未安装TK的电脑上无法运行)

-w    制作窗口程序

-c    制作命令行程序(默认)

-X    制作使用UPX压缩过的可执行程序(推荐使用这个选项,需要下载UPX包,解压后upx.exe放在Python(非PyInstaller)安装目录下,下载upx308w.zip)

-o DIR  指定输出SPEC文件路径(这也决定了最后输出的exe文件路径)

–icon=[ICO文件路径] 指定程序图标

-v [指定文件] 指定程序版本信息

-n [指定程序名] 指定程序名称

–distpath=D:/dist 输出到指定位置
