因为工作中需要给交付团队开发桌面工具，考虑到交付团队多使用Mac，调研了一下发现PyQt5可以实现跨平台，满足工具开发需要，就用其开发了桌面工具。现以ubuntu开发环境为例总结一下开发过程。
目录
1.安装python3.7
2.安装PyQt5版本5.15.2
3.protobuf库使用
4.编写pyqt5程序
4.1设计界面并产生py代码
4.2封装mainwindow.py成MainWidget.py
4.3调用MainWidget.py
5.打包
i. 安装pyinstaller
ii. 打包
sudo apt-get install python3.7
sudo pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple/ pyqt5==5.15.2
另外一种安装方法：
sudo pip3 install PyQt5==5.15.2
i. 查看版本
sudo pip3 index versions protobuf
ii. 卸载
sudo pip3 uninstall protobuf
iii. 安装指定版本
sudo pip3 install protobuf==3.19.0
i. 安装Qt Designer并使用其设计界面
例如得到界面文件mainwindow.ui
ii. .ui文件转.py文件
python3 -m PyQt5.uic.pyuic -o mainwindow.py mainwindow.ui
