install nijs using only npm

[dckc]

I started a fresh docker container, cloned this project, and ran the nijs-build pkgs.js -A hello example, and blammo:

$ docker run -ti node bash
root@13faaf1261d9:/# npm install -f nijs

root@13faaf1261d9:/# git clone https://github.com/svanderburg/nijs.git
root@13faaf1261d9:/# cd nijs/
root@13faaf1261d9:/nijs# cd tests/

Hmm weird. I must admit that I haven't tried docker, but when I install nijs with the release.nix expression, via Nixpkgs, or directly with npm on my local machine, it just seems to work fine for me.

I think docker is less relevant than installing nijs from npm vs from git sources and nix-env.

I just tested installing the current git version 2003ee7fa9d032e7803664414506224b86d16a9d with nix-env -f release.nix -iA nodePackages.nijs outside docker, in this Ubuntu 16.04 machine, and that works fine.

I just tried using the git sources and nix-env within the docker image (which is based on alpine, btw) and lost in a different way:

bash-4.3# apk update
bash-4.3# apk add git curl
bash-4.3# curl https://nixos.org/nix/install | sh

@dckc To install nijs from the release expression included in this repo, use:

$ nix-env -f release.nix -iA package.x86_64-linux

[dckc]

Ah right... well, I lose doing that too (details below).

I think I'm getting lost in a maze of twisty docker containers. And that's really beside the point. I should revise the issue to show my real goal...

$ docker run --rm -ti nixos/nix bash

bash-4.3# git clone https://github.com/svanderburg/nijs.git
bash-4.3# cd nijs
bash-4.3# nix-env -f release.nix -iA package.x86_64-linux

bash-4.3# cd tests
bash-4.3# nijs-build pkgs.js -A hello

My real goal is for people to just check out my project and npm install... or perhaps a short list of npm commands.

In particular, I'd like nix to get installed automatically. I suppose that's a pretty tall order, but npm install electron would seem to involve a similar feat. But I don't suppose it needs to write to /.

[trusktr]

Yep, npm install electron is contained in the project's node_modules, not /.
