@hunterloftis other issues people have seem to point at dependencies issues. I was able to replicate your issue with 2.0.0 but was able to install 1.1.0 so I went to go see what was different between the two dependency wise, but could not find a tag for 2.0.0 in the github repo, could you push it up?

I believe this was an issue with an invalid main property in package.json
