I need to learn Ruby on Rails for my new job. I’m a little thrilled about this chance to learn a new language, and I’m trying to get started with it on my Macbook which runs OS X El Capitan 10.11.5. I already have Ruby here, I don’t remember if pre-installed though. It’s out of date and I wanted to upgrade, as this resource Getting Started with Rails recommends version 2.2.2 or higher.
First step I took was to get RVM (Ruby Version Manager):
curl -sSL https://get.rvm.io | bash -s stable --ruby
Then I received this message:
” * To start using RVM you need to run
source /Users/catzie/.rvm/scripts/rvm
in all your open shell windows, in rare cases you need to reopen all shell windows.”
And so I ran:
source /Users/catzie/.rvm/scripts/rvm
Then:
rvm install 2.4
Which returned this message:
Already installed ruby-2.4.0.
To reinstall use:rvm reinstall ruby-2.4.0
Finally, I ran this:
rvm use 2.4 --default
My next step was to install SQLite3 on my OS X as per instructions found here on SQLite – Installation.
I got this message after following the instructions:
SQLite version 3.17.0 2017-02-13 16:02:40
Enter “.help” for usage hints.
Connected to a transient in-memory database.
Use “.open FILENAME” to reopen on a persistent database.

More on this in the future.
Reference: Can I upgrade to the current version of Ruby (2.2.3) on OS X v10.6.8?
