Do you have Jekyll installed? (gem install jekyll)

[husnimubarok]

yes but it return:

`root@vultr:~/OpenMapKitServer# npm start

That looks to me like a screwed up RVM or Jekyll installation. I'd have a look at the jekyll paths it's complaining about to see if anything looks weird.

I just tried installing jekyll-3.6.2 on ruby-2.3.1 (I use rbenv, but it shouldn't matter) and it worked for me.
