json – 在执行“npm安装”后安装的npm模块太多

我的package.json:
{
  "name": "thumbnaillist-gulp","version": "1.0.0","description": "","main": "index.js","scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },"author": "","license": "ISC","dependencies": {
    "browserify": "^12.0.1","gulp": "^3.9.0","gulp-concat": "^2.6.0","gulp-react": "^3.1.0","gulp-util": "^3.0.7","react": "^0.13.3","react-script-loader": "0.0.1","reactify": "^1.1.1","vinyl-source-stream": "^1.1.0","watchify": "^3.6.1"
  }
}

奇怪的是,在执行“npm安装”之后,除了依赖关系字段中列出的模块之外,还安装了其他模块,例如

有什么提示吗?我的NPM坏了吗或者我没有以正确的方式写一个package.json.

解决方法

没有没有任何问题,NPM现在将安装所有依赖关系到根模块文件夹,除非有版本冲突.您看到的所有其他模块都是您安装的模块的依赖关系.

NPM 3.0.0 release notes

Your dependencies will now be installed maximally flat. Insofar as is possible,all of your dependencies,and their dependencies,and THEIR dependencies will be installed in your project’s node_modules folder with no nesting. You’ll only see modules nested underneath one another when two (or more) modules have conflicting dependencies.
