当我执行 npm start 时出现此错误

Question

我对此完全陌生node.js！！如何克服以下错误。尝试了网上给出的所有可能的解决方案。而且这个错误发生在环境变量改变之后。请帮我解决这个问题。提前致谢。

C:\project\nodetest1>npm start

> nodetest1@0.0.0 start C:\project\nodetest1
> node ./bin/www

package.json 是

 {
  "name": "nodetest1",
  "version": "0.0.0",
  "private": true,
  "scripts": {
  "start": "node ./bin/www"
 },
  "dependencies": {
  "body-parser": "~1.8.1",
  "cookie-parser": "~1.3.3",
  "debug": "~2.0.0",
  "express": "~4.9.0",

  "morgan": "~1.3.0",
  "nodemon": "*",
  "passport": "*",
  "passport-local": "*",

 }

}

我也遇到过这个错误 also.This 是由于环境中的路径变量引起的。因此只需更改 unistall node.js 并从系统中删除路径变量，并从中删除 Npm 和 npm-cache AppData\Roaming\npm。然后安装节点它肯定会工作
