Not using it as an example of a 'stellar' package manager. Just one where the dependencies can be defined with version. I was under the impression that apt-get will just use the most recent version.
apt-get/dpkg do have the ability to specify package versions, including specifying versions equal to, greater than, or less than. It also has the ability to specify build time and run time dependencies separately.
You can specify a version. The real trouble is that you generally cannot have multiple versions of the same package installed on the same system. Thus, if multiple packages specify different versions as dependencies, you're hooped.
So that is something npm does, AFAIK.
Isn't it even possible to have multiple different versions of a sub package in the dependency tree of one project?
