install ruby when you don't do much ruby but want to download a gem

when gem install trello_cli yields permission errors:

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.

you should download another ruby and use that as the default.

brew install ruby

find the version:

cd /usr/local/Cellar/ruby
ls

get the bin folder path:

cd /usr/local/Cellar/ruby/2.2.3/bin
pwd | pbcopy

and attach it to your PATH in your .bash_profile:

export PATH="/usr/local/Cellar/ruby/2.2.3/bin:$PATH"

then source that shit:

source ~/.bash_profile

and get on with life:

gem install trello_cli
