I'm running Node 6.3.0 on a MackBook I just set up running OS X 10.11
我正在运行OS X 10.11的MackBook上运行Node 6.3.0
I installed Node using Homebrew and I noticed that when I run npm install it installs what amounts to dozens and dozens of extra packages.
我使用Homebrew安装了Node，我注意到当我运行npm install时，它会安装数十个额外的软件包。
For instance when I run npm install gulp --save it installs gulp but when I look in the node_modules directory I see what looks like 30 or 40 extra folders. This is different then when I run npm at home on my Linux box. When I do that I only see the one directory.
例如，当我运行npm install gulp --save时，它会安装gulp但是当我查看node_modules目录时，我会看到30或40个额外文件夹。这与我在Linux机上运行npm时不同。当我这样做时，我只看到一个目录。
Am I doing something incorrectly?
我做错了什么吗？

You are probably using an older version of npm (< 3) on your Linux box. With npm 3 they changed the way they store dependencies and try to flatten the dependencies tree. e.g. If you had a project A that depends on B and B depends on C it would look like this:
您可能在Linux机器上使用旧版本的npm（<3）。使用npm 3，他们改变了存储依赖关系的方式，并尝试压缩依赖关系树。例如如果你有一个依赖于B和B依赖于C的项目A，它将如下所示：
npm 2:
npm 2：
A/node_modules/B/node_modules/C
npm 3:
npm 3：
A/node_modules/B
A/node_modules/C
Hope this helps.
