ungit: Ungit doesn't work inside a alpine container in versions after 1.4.26

Hi guys.

I don’t know what changed in ungit after version 1.4.26 but it stopped working in my node:8-alpine container. I’m currently only using version 1.4.26.

Below are the container logs:

Here’s my old dockerfile. New one installs only version 1.4.26 of ungit with: npm install -g ungit@1.4.26
