Fix error due to Ruby version being < 2.0.0. #11

Closed ErikGartner closed 6 years ago

When installing building my Jekyll page on Ubuntu 16.04 it crashes due to:

-----> Building Jekyll site
       Fetching gem metadata from http://rubygems.org/...........
       RubyGems 1.8.23 is not threadsafe, so your gems will be installed one at a time. Upgrade to RubyGems 2.1.0 or higher to enable parallel gem installation.
       Fetching rake 12.3.0
       Installing rake 12.3.0
       Gem::InstallError: rake requires Ruby version >= 2.0.0.
       An error occurred while installing rake (12.3.0), and Bundler cannot continue.
       Make sure that `gem install rake -v '12.3.0'` succeeds before bundling.

       In Gemfile:
       rake

To me this seems to be because the system version of Ruby is used and not the rbenv version.

As a fix I just added rbenv global <version> and that fixes the issue for me.

Makes sense! Thanks!
