This post is a little memory aid for myself, as I repeatedly had the problem of having to re-set up my ruby/gems/bundler environment. I need this mainly to run jekyll.
The key is to get the shell environment set up correctly and to install bundler. Bundler then takes care of setting up jekyll and its dependencies based on an appropriate Gemfile that resides in the root directory for my homepage. In that directory I only have to say
bundle and everything happens automatically from there, at least as long as the above mentioned prerequisites are met.
