我使用 qgis 编写 python 脚本来显示谷歌地图基础层，并设置环境变量如下：
PYTHONHOME=C:\Program Files\QGIS 3.16\apps\Python37
PYTHONPATH=C:\Program Files\QGIS 3.16\apps\Python37; C:\Program Files\QGIS
3.16\apps\Python37\Scripts\; C:\Program Files\QGIS 3.16\apps\Python37\Lib\; C:\Program
Files\QGIS 3.16\apps\Python37\Lib\site-packages\; C:\Program Files\QGIS
3.16\apps\Python37\DLLs\; C:\Program Files\QGIS 3.16\apps\qgis-ltr\python\
Path= %PATH%; C:\Program Files\QGIS 3.16\bin\; C:\Program Files\QGIS 3.16\apps\qgis-ltr\bin\;
C:\Program Files\QGIS 3.16\apps\Qt5\bin\; C:\Program Files\QGIS 3.16\apps\Python37\;
C:\Program Files\QGIS 3.16\apps\Python37\Lib\; C:\Program Files\QGIS
3.16\apps\Python37\Scripts\; C:\Program Files\QGIS 3.16\apps\Python37\Lib\site-packages\
使用 vs 2019 运行脚本时，它成功显示了地图，但是当我使用 pyinstaller 转换为 exe 文件时，它显示错误：找不到现有的 PyQt5 插件目录这是 pyinstaller 跟踪：
