Windows下用node-windows部署Node.js后台服务遇.vbs脚本引擎错误

尝试用node-windows将Node.js脚本部署为Windows后台服务，已全局安装并关联node-windows，但执行service.js时出现错误：

Windows Script Host: There is no script engine for file extension ".vbs"

已尝试在CMD中执行assoc .vbs=VBSFile命令，问题仍未解决。

相关代码 #

service.js #

var Service = require("node-windows").Service;

console.log("entered");

// Create a new service object
var svc = new Service({
  name: "myService",
  description: "my service",
  script:
    "C:\\path-to-my-script\\example.js",
});

// Listen for the "install" event, which indicates the
// process is available as a service.
svc.on("install", function () {
  console.log(" entered install ");
  svc.start();
});

// Listen for the "start" event and let us know when the
// process has actually started working.
svc.on("start", function () {
  console.log(
    svc.name + " started!\nVisit http://127.0.0.1:3000 to see it in action."
  );
});

svc.on("error", function () {
  console.log(svc.name + " error occured");
});

svc.install();

console.log(" completed");

example.js #

var http = require("http");

const hostname = "127.0.0.1";
const port = 3000;

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader("Content-Type", "text/plain");
  res.end("Hello World");
});

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});

解决方法 #

• 修复VBScript脚本引擎关联
  打开管理员CMD，执行两条命令：

  assoc .vbs=VBSFile
  ftype VBSFile=%SystemRoot%\System32\WScript.exe "%1" %*
  

  第一条关联扩展名与文件类型，第二条指定该类型的执行程序。

• 重新注册VBScript引擎
  管理员CMD中执行：

  regsvr32 vbscript.dll
  

  确认弹出注册成功提示。

• 以管理员身份运行安装命令
  右键CMD/PowerShell选择“以管理员身份运行”，再执行node service.js，node-windows安装服务需要管理员权限。

• 重装node-windows
  卸载并重新全局安装：

  npm uninstall -g node-windows
  npm install -g node-windows
  

• 检查WScript.exe完整性
  确认C:\Windows\System32\WScript.exe存在，若缺失需修复系统组件或从同版本正常系统复制该文件。
