npm start Microsoft JScript 运行时错误 800A138F 预期对象 [英] npm start Microsoft JScript runtime error 800A138F object expected

问题描述

开始使用 NPM...

我可以运行以下命令来启动我的应用程序.

节点应用

但是当我运行以下命令时，出现以下错误:

npm 开始

<块引用>

Windows 脚本宿主预期对象

Microsoft JScript 运行时错误

App.js:

var 端口 = 5000;var express = require('express');

包.json:

<代码>{名称":2"，版本":1.0.0"，描述": ""，主":app.js"，脚本":{开始":app.js"},作者": ""，许可证":ISC"，依赖":{快递":^4.13.3"}}

我当然已经运行了这个命令:

npm install express --save

好像NPM找不到快递包?为什么不?

解决方案

我知道现在回答为时已晚，但万一像我这样的流浪者将来也面临同样的问题..

解决方案:

需要在脚本中的 app.js 之前添加 node 关键字.所以，启动脚本应该

<代码>脚本":{开始":节点 app.js"},

这为我解决了.

Getting started with NPM...

I can run the following command to start my app.

node app

But when I run the following command, I get the following error:

npm start

Windows Script Host Object expected

Microsoft JScript runtime error

App.js:

var port = 5000;
var express = require('express');

Package.json:

{
  "name": "2",
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "scripts": {
    "start": "app.js"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "express": "^4.13.3"
  }
}

And I've run this command of course:

npm install express --save

Seems like NPM can't find the express package? Why not?

解决方案

I know its too late to answer, but in case any wanderer like me faces the same problem in future..

Solution:

need to add node keyword ahead of app.js in script. So, start script should

"scripts": { "start": "node app.js" },

That solved for me.
