I'm opening this issue because:

• npm is crashing.
• npm is producing an incorrect install.
• npm is doing something I don't understand.
• Other (see below for feature requests):

What's going wrong?

I have monorepo project. In this repo I have two folders: one with actual application and another one with component. Application depends on the component. After npm install I saw that not all dependencies were installed. In particular dependencies for the component. My Component has postinstall hook which runs tsc (typescript to be compiled) and it fails, because some packages weren't installed

How can the CLI team reproduce the problem?

1. Create package folder
2. npm init in it
3. add some dependencies in it, also devDependencies just to check
4. Create another package
5. add first folder as a dependency
6. run npm install

supporting information:

• npm -v prints:
  3.10.3
• node -v prints:
  v6.4.0
  v6.3.1
• npm config get registry prints:
  https://registry.npmjs.org/
• Windows, OS X, or Linux?:
  MacOS X El Capitan 10.11.6 (15G31)

Extra note:

if I'll add npm install && tsc to postinstall it will toggle, somehow, packages installation in application - it means that all component dependencies will also appear in application node_modules
