git-hours doesn't install

Same error as #14 is reported when attempting to run git-hours.

First was using node 8.10.0, but I tried switching to the latest 5 and latest 4 using nvm and I still couldn’t get it working.

Addition: I also tried installing the latest version of nodegit which doesn’t produce an error when I install it (sudo npm install -g nodegit@0.20.0) and that didn’t work either

docker run --rm -v $(pwd):/code khor/git-hours

Also doesn’t install for me. I installed nodegit before. Not sure whether it is the same issue.
