Can't use package from Github

[msikma]

I'm trying out Lyp right now for the first time, but some things are a little confusing. I made a package on Github with some of my code, but I can't seem to make it work.

$ lyp resolve sonata-op106-iii.ly
Installing github.com/msikma/ly-ms@0.1.2
$ lyp compile sonata-op106-iii.ly --verbose
Lyp 1.3.5
Missing package dependency github.com/msikma/ly-ms>=0.1.2 in sonata-op106-iii.ly:11: 

  \require "github.com/msikma/ly-ms>=0.1.2"

You can install any missing packages by running:

  lyp resolve sonata-op106-iii.ly

I'm not sure how to fix this. The package is definitely installed though:

pwd
/Users/msikma/.lyp/packages/github.com/msikma/ly-ms@0.1.2

As far as I know I'm using it exactly as described in the readme...
