scsynth not found on Linux

[nhthn]

I'm on Ubuntu 16.04. supercolliderjs doesn't seem to find scsynth even if it's in my PATH:

$ which scsynth
/home/nathan/usr/local/bin/scsynth

var sc = require("supercolliderjs");
sc.server.boot();

Promise {
  _bitField: 0,
  _fulfillmentHandler0: undefined,
  _rejectionHandler0: undefined,
  _promise0: undefined,
  _receiver0: undefined }
> error  : Failed to boot /usr/local/bin/scsynth

Of course, I can fix this by manually setting the correct path in the options with sc.server.boot({ scsynth: ... }), so it's not a huge issue.

It needs an explicit path. Only linux has scsynth installed on your PATH. OS X and windows do not do this.

supercollider.js is also intended to be used with an included portable version of scsynth.

You can use a config file ~/.supercollider.yaml so you don't have to set it in your code.
