node.js - 为什么npm安装失败: Error Etarget?

Question

我是 Node 新手。我尝试运行我的第一个meanjs 项目。我有一个包 json 文件:

{
  "name": "notetest1",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "node ./bin/www"
  },
  "dependencies": {
    "body-parser": "~1.13.2",
    "cookie-parser": "~1.3.5",
    "debug": "~2.2.0",
    "express": "~4.13.1",
    "jade": "~1.11.0",
    "morgan": "~1.6.1",
    "serve-favicon": "~2.3.0",
    "mongodb": "~3.0.0",
    "monk": "~1.0.1"
  }
}

NodeJS

node -v
v4.1.1

NPM

 npm -version
 2.7.5

MongoDB

mongod -version
db version v3.0.2
git version: nogitversion

我想通过运行 npm install 命令来安装依赖项，但出现一些错误:

问题是什么？

Answer 1

您有一个实际上不可用的 mongodb 版本。将版本更改为 x.x.x´ 或运行 npm install mongodb --save` 将其更新为您的 package.json
