执行打包好的程序，程序闪退，但是闪退没法跟踪问题，于是在命令行窗口执行exe，显示如下：
D:\>"D:\python project\demo\dist\demo.exe" Traceback (most recent call last): File "demo.py", line 3, in <module> File "d:\python project\demo\venv\lib\site-packages\PyInstaller\loader\pyimod03_importers.py", line 627, in exec_module exec(bytecode, module.__dict__) File "lib\site-packages\PyQt5\__init__.py", line 41, in <module> File "lib\site-packages\PyQt5\__init__.py", line 33, in find_qt ImportError: unable to find Qt5Core.dll on PATH [11632] Failed to execute script demo
这种问题主要原因，Qt5Core.dll不在程序执行的路劲里，解决办法：在压缩好的包文件夹下搜索Qt5Core.dll文件，将该文件放置到PyQt5\QT\bin 下面就OK了！
