Issues installing in an Ubuntu Docker container

[Joshfindit]

Quick note for anyone coming across this later:

I was having a lot of issues getting svg2png to install (see Below), but all it took was switching to yarn:

1. Install Node 8 according to https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions
2. yarn global add svg2png
3. Use it

Below

$ npm install svg2png -g # Running as root since the Docker container is designed that way. sudo is not even installed
/root/.npm-global/bin/svg2png -> /root/.npm-global/lib/node_modules/svg2png/bin/svg2png-cli.js

> phantomjs-prebuilt@2.1.15 install /root/.npm-global/lib/node_modules/svg2png/node_modules/phantomjs-prebuilt
> node install.js

module.js:473
      throw err;
      ^

Yes, I'm aware that this is a very likely a general npm issue, but svg2png was all I was concerned about and the next searcher may be in a similar situation
