I went through this wonderful experience a few weeks ago. You're not allowed to access the network in src_prepare, so that might be contributing to your weirdness. I came up with two options: 1) Run `npm install` on your dev machine, and then package up the result as a tarball. Generate the manifest from the tarball, and then in your src_install, just copy stuff over. src_install(){ local npm_module_dir="/usr/$(get_libdir)/node/${PN}" insinto "${npm_module_dir}" doins -r whatever ... } This is the lazy way, but avoids you having to package 1,000 other things all written by people who just "learned to code" by googling HOW DO I HTML5. 2) The right way to do it is to use an eclass and install all of the dependencies using separate packages. As you can imagine, this is a nightmare if you have more than a few dependencies (looks like you do). I started an eclass for npm packages. I left the overlay here: https://github.com/orlitzky/npm but no one else seemed interested in having it in-tree, and the whole ecosystem is kind of scary to me anyway. So, for the large package I need, I'm doing it the lazy way: npm install on my machine, and make an ebuild for the resulting huge tarball.
