node.js - 节点窗口不卸载节点服务

Question

我正在使用 node-windows 安装和卸载节点后端 RESTAPI windows 服务。安装时它工作得很好。但是当我尝试卸载该服务时，它会导致问题。下面是卸载windows节点服务的代码，我还附上了错误的截图

var Service = require('node-windows').Service;
var config = require('./config.json');

// pre-Installation 
/**
* npm install - g node- windows
* npm link node-windows
*/

// Create a new service object
var svc = new Service({
    name: 'GRIT Node Server',
    description: 'The new Node.js based GRIT Server',
    script: config.absoluteProgramDirectory,
    nodeOptions: [
        '--harmony'
    ]
});

// Listen for the "install" event, which indicates the
// process is available as a service.
svc.on('install', () => {
    svc.start();
});

console.log('program sucessfully uninstalled');

svc.uninstall();
