npm将所有依赖项和子依赖放在同一个文件夹中。

Question

我有一个package.json文件，在我的项目中有大约20个依赖项。当我这么做

npm install

它将所有依赖项和子依赖项放在最上面的node_modules目录中。它包含数百个模块，而它只应该是我的20个模块。子依赖项应该在我的主要依赖项下的node_module目录中，但是它已经创建了一个扁平的结构。

我在Ubuntu 14.04上使用npm 3.5.4和节点0.10.41

有谁能帮助我像正确的树结构那样安装模块吗？

编辑-添加我的packages.json文件：

这是故意的行为。由于版本3，npm尝试去复制依赖项，并尽可能使用平坦的树。
