二、生成的安装文件可以使用一下命令来执行控制服务:

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

或者

sc  create DectFacePythonServer（运行的服务程序） binPath= E:\python\pydev\src\dist\ProductCollectWin32ServiceSetup.exe 

注意上面“=”后面是带空格的

sc start DectFacePythonServer

sc delete DectFacePythonServer

详情请运行 sc --help。
