Ruby gems home on Windows - ruby

I installed ruby for windows and then rubygems but am getting the following error when trying to use rubygems to install bundler.

For some reason I was unable to install rubyzip. I needed to
download the gem into my system
navigate to the folder
execute gem install --force --local *.gem
When I did the above steps the gem was installed.

How to install Jekyll on Mac 10.11.6

Hello and thanks for your help in advance.
I'm having trouble installing Jekyll because I receive the following error:

This is slightly different than the question already posted, here I've also followed all of those recommendations but nothing is working.

I'm able to successfully install jekyll on my Mac but I'm not using system Ruby. I'd highly recommend using RBEnv to manage your Ruby installation on OSX. You'll find it much easier to work with than trying to deal with the system version or the Brew version. With it you can swap out Ruby versions easily and gem management is simpler.
Thanks for all the responses.
I ended up uninstalling ruby and re-installing it.
Then I started getting other issues, but new issues are good!
And this finally fixed it.
sudo gem install -n /usr/local/bin/ jekyll
Now I'm running ruby 2.0. Hope this helps, let me know if anyone has any questions!

ruby gem not found although it is installed (Ubuntu 14)

I installed the my gem:
gem list --local | grep active
activesupport (4.1.7)
activesupport-inflector (0.1.0)
But when I run ruby, it can't find it:
/usr/bin/ruby1.9.1 -e 'require "active_support/inflector"'
-e:1:in `require': cannot load such file -- active_support/inflector (LoadError)
from -e:1:in `<main>'
I am at a loss as to why this setup isn't working.
I found a workaround. I'm not sure what the cause of my issue is, but apparently there is some change with Ruby 1.9.2+. The following works fine:
/usr/bin/ruby1.9.1 --disable-gems -e 'require "rubygems"; require "active_support/inflector"'

I'd suggest trying http://rubygems.org and seeing if that works. https should work, but at least then you'd know more precisely what the problem is. You'll probably find this config information in your ~/.gemrc file.

after I've installed jekyll on Ubuntu 12.04 with
sudo apt-get install ruby1.9.1-dev && sudo gem install jekyll
This is my gem env:

How can i solve it?
Running gem install json should fix the LoadError.
Commander throws that program version required error whenever there is a problem loading in the executable (in this case, bin/jekyll). As 1.8.7 can't load an internal json library (introduced in 1.9), you'll need to install the gem.
