Keep symlinks when running `npm install`

问题

If we do:

npm link x

and then we run npm install, it will overwrite the symlinked package.

Is there a way to run npm install without overwriting a symlinked package? something like:

npm install --preserve-symlinks

or

npm install --keep-symlinks

here is the issue in the NPM issue tracker:
