Missing theme file on Jekyll installed with RVM

Question

I've error when i install Jekyll on MacOS 10.13.2 with 'gem install jekyll' command:

ERROR: While executing gem ... (Gem::FilePermissionError) 

To solve this problem i am installed RVM and install Jekyll with RVM. Jekyll runs perfectly. But i've some critical problem here. Jekyll comes with default theme named 'Minima'. I want to customize theme, but i check site file, includes file is not here. So can't customize theme.

To find the includes file i use that command on the terminal:

which gem minima

Output:

/Users/bekircem/.rvm/rubies/ruby-2.4.1/bin/gem

So i can't access to includes and other similiar files.

How can i fix that problem? Any suggestions?

Ok. I found a solution . Detailed description on the Jekyll.org about theme defaults.
