"docker exec -it photon jekyll serve --watch --host=0.0.0.0" fails on install

[ghost]

Followed the instructions, forked the repo and cloned it, installed npm, and got an error. It said to tell you what I told you in the subject line and to attach npm-debug.log. I don't know how to attach files to issues and the file is short so I'm just copy pasting it here:
