Why isn't the gem installed?

Question

Redmine

I want to install plugins on bitnami redmine and faced the following problem, I can't install redcarpet. When installing I get the following log

[email protected]:/home/drem1lin# gem install redcarpet -v '3.3.4'

This is my first experience and I couldn't find anything that can fix it, installed ruby-dev, ruby-all-dev
did gem update --system

Answer 1

it's not ruby, it can't execute some redcarper shell script.
Try installing
it should help
