在执行“npm安装”之后安装了太多的npm模块

My package.json:

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",

    "reactify": "^1.1.1",
    "vinyl-source-stream": "^1.1.0",
    "watchify": "^3.6.1"
  }
}

The weird thing is that after I execute "npm install", besides the modules listed in the dependencies field, other modules are also installed, such as

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

Any hint on this? Is my NPM broken? Or I did not write a package.json in a correct way.

任何提示吗?是我NPM坏了?或者我没有写一个包裹。json是正确的。

No there's nothing wrong, NPM now installs all dependencies to the root modules folder unless there is a version conflict. All those other modules you are seeing are dependencies of the modules you installed.

没有问题，NPM现在将所有依赖项安装到根模块文件夹，除非存在版本冲突。您看到的所有其他模块都是您安装的模块的依赖关系。

From the NPM 3.0.0 release notes:

从NPM 3.0.0发行说明:

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.

您的依赖项现在将被安装到最大平面上。在尽可能的情况下，您的所有依赖项、它们的依赖项和它们的依赖项都将安装在项目的node_modules文件夹中，没有嵌套。只有当两个(或多个)模块具有相互冲突的依赖关系时，才会看到模块相互嵌套。

I hope Alexander O'Mara answer is helpful for you If you still want or for those who want to use dependencies like older version

我希望Alexander O'Mara的回答对您有帮助，如果您仍然需要，或者对于那些想要使用依赖关系的人，比如旧版本

you can use

您可以使用

npm install --legacy-bundling

npm安装——legacy-bundling

If you always want use

如果你一直想用。

npm set legacy-bundling=true

npm legacy-bundling = true

and use can run as usual

使用也可以正常运行

npm install

npm安装
