我正在尝试使用这个project.json文件安装项目的依赖项：

{
  "name": "Pizza",
  "version": "1.0.0",
  "description": "NIT Project",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "TheSmokingGnu",
  "license": "ISC",
  "dependencies": {
    "basil.js": "^0.4.3",
    "brfs": "^1.4.3",
    "ejs": "^2.4.1",
    "grunt": "^0.4.5",
    "grunt-browserify": "^4.0.1",
    "grunt-contrib-watch": "^0.6.1"
  }
}

我只是cd到目录（或使用webshtorm的控制台），并运行npm install：

npm install
npm ERR! code ENOTFOUND
npm ERR! errno ENOTFOUND
npm ERR! network request to http://registry.npmjs.org/ejs failed, reason: getaddrinfo ENOTFOUND ip ip:80
npm ERR! network This is a problem related to network connectivity.
npm ERR! network In most cases you are behind a proxy or have bad network settings.
npm ERR! network
npm ERR! network If you are behind a proxy, please make sure that the
npm ERR! network 'proxy' config is set properly.  See: 'npm help

我正在使用Windows 10（昨天刚刚安装），系统防火墙关闭。我没有任何使用proxys的意图，我的配置列表看起来像这样：

>npm config list
; cli configs
metrics-registry = "http://registry.npmjs.org/"
scope = ""
user-agent = "npm/5.5.1 node/v8.9.1 win32 x64"

; userconfig C:\Users\taras\.npmrc
http-proxy = "http://username:password@ip:port"
https-proxy = "http://username:password@ip/:port"
registry = "http://registry.npmjs.org/"
strict-ssl = false

; builtin config undefined
prefix = "C:\\Users\\taras\\AppData\\Roaming\\npm"

; node bin location = C:\Program Files\nodejs\node.exe
; cwd = D:\Downloads\JS-Pizza-master\JS-Pizza-master
; HOME = C:\Users\taras
; "npm config ls -l" to show all defaults.

最后，我的错误日志：
