python pyinstaller 打包exe报错

今天用python 使用pyinstaller打包exe出现错误

环境pyqt5 + python3.6 32位

在导入pyqt5包之前加上如下代码

import sys
import os
if hasattr(sys, 'frozen'):
    os.environ['PATH'] = sys._MEIPASS + ";" + os.environ['PATH']

from PyQt5.QtWidgets import QApplication, QMainWindow
from pyqt_ui.MainWindow import MainWin

if __name__ == '__main__':
    app = QApplication(sys.argv)
    mainWindow = QMainWindow()
    main_dialog = MainWin(mainWindow)
    mainWindow.show()
    sys.exit(app.exec_())

运行

pyinstaller -F main2.py

打包成功

运行出现正常界面

注：为避免重复将main.py 更改为main2.py了
