二、生成的安裝檔案可以使用一下命令來執行控制服務:

DectFacePythonServer.exe install
DectFacePythonServer.exe start
DectFacePythonServer.exe stop
DectFacePythonServer.exe remove。

或者

sc create DectFacePythonServer（執行的服務程式） binPath=E:\python\pydev\src\dist\ProductCollectWin32ServiceSetup.exe

注意上面“=”後面是帶空格的

sc startDectFacePythonServer

sc deleteDectFacePythonServer

詳情請執行 sc --help。
