npm不仅加载我在package.json中清除的软件包

Question

I'm working on a small project using npm, bower and grunt. When I do an "npm install" on my PC, its loading a lot wired stuff (see screenshot). But when I do the same on my MBA its loading only my declared packages:

{
  "private": true,
  "devDependencies": {
    "grunt": "^0.4.5",
    "grunt-grunticon": "^2.2.2"
  }
}

Answer 1

npm3 (which is used by default since Nodev5) flattens the dependency tree. You may still be using npm2 (which doesn't do that) on the other system.

From the changelog :

Flat, flat, flat!

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.
