Trying to run Rammmerhead on Linux

[Lavadude82]

I recently threw away my Windows License to my Microsoft and decided, Linux is better for server side. I installed Debian with KDE, and installed Node, VS-Code, and Firefox, but it doesn't work. I get this error when trying to run it on default and configured settings using "npm install && npm run build && node src/server.js", "npm WARN deprecated source-map-url@0.4.1: See https://github.com/lydell/source-map-url#deprecated
npm WARN deprecated urix@0.1.0: Please see https://github.com/lydell/urix#deprecated
npm WARN deprecated resolve-url@0.2.1: https://github.com/lydell/resolve-url#deprecated
npm WARN deprecated source-map-resolve@0.5.3: See https://github.com/lydell/source-map-resolve#deprecated
npm WARN deprecated babel-eslint@10.1.0: babel-eslint is now @babel/eslint-parser. This package will no longer receive updates.
