windows中使用node express 4.12创建的web应用，使用npm start启动报错？

Question

创建应用：

$ express -c stylus myapp

然后用

npm install && npm start

启动失败，报错：

npm ERR! Windows_NT 6.1.7601

但是使用

node bin/www

则成功运行，请问这是为什么？是不是因为windows cmd没有ls命令？

//package.json
{
  "name": "myapp",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "node ./bin/www"
  },
  "dependencies": {
    "body-parser": "~1.12.0",
    "cookie-parser": "~1.3.4",
    "debug": "~2.1.1",
    "express": "~4.12.2",
    "jade": "~1.9.2",
    "morgan": "~1.5.1",
    "serve-favicon": "~2.2.0",
    "stylus": "0.42.3"
  }
}

Answer 1

你看看package.json里面有没有 start命令先

Answer 2

从报错看:不能执行.node ./bin/www. 但是可以执行 node bin/www 显然./ 是bash风格

两个建议:
1.升级NPM

 npm -v
 npm update 

2.npm 只是包管理器,可以拆解 npm install && npm start 运行,正如你正确的做法.
By the way,
一般运行nodejs的项目,都是通过node ***.js来运行的,所谓的
npm start grunt serve grunt server都是接管了这类指令

Answer 3

同样的错误，楼主解决了么？
