Package discovery was annoying. With Ruby, gems, and bundler I can define my project gems and install them with 'bundle install'. Any machine I move to it does that. It's fantastic. With node and npm you can do more or less the same thing. Maybe with easy_install you can now, but I remember having to manually download packages and easy_install them. No package management, no easy discovery, no project dependency management.
